3 EUROPE ASIA NORTH & SOUTH AMERICA Our stock spring product listing continues to grow. In this catalogue you ll find hundreds of new springs including high performance beryllium copper battery springs, REDUX wave springs, constant force springs and more sizes of 316 stainless steel Lite Pressure compression springs. In total over different types of spring. Beryllium copper, one of the hardest, strongest and most hard wearing copper alloys, improves the physical properties of our latest battery springs while a silver coating enhances electrical and thermal conductivity performance and makes soldering easier. These high performance battery springs will appeal to engineers who are developing devices where exceptional endurance and ruggedness are key requirements. Both our standard and beryllium copper spring types are designed to adjust to varying battery lengths and provide secure, low contact resistance and dependable connections. All provide fast, efficient and reliable contacts in most situations where portable power is required, for example, in self contained moulded battery compartments or tailored applications. Our standard range is produced in nickel coated music wire to harmonize with the nickel plated containers commonly used in the manufacture of alkaline batteries. The use of similar materials prevents galvanic corrosion and enhances wear resistance. The nickel also adds corrosion protection and superior electrical conductivity. Four mounting configurations are offered interior, exterior, adjustable and double - all of which have been developed to work with the most popular battery sizes. restraining force. Usually they are tightly coiled on a drum and either the free end or the drum is attached to the load. Four life cycle ranges are offered covering loads from 1.02 to 73.42N (0.23 to 16.50Ib). Typical applications include counterbalance springs, car seat belt and cable retractor mechanisms. Two hundred additional sizes of Lite Pressure compression springs in Type 316 stainless steel have been added. Designed to meet demands for compression springs combining low spring rates with large diameters these high index springs deliver from 7 to 38kPa 80% deflection. Typical applications include valves, pistons, syringes, motor brushes, dispensers, contacts and toys. Lee Spring s custom spring design and manufacturing service has also been strengthened with a dedicated and technical team in place to handle the provision of tailored solutions. Full details are included along with a suite of reproducible specification forms for spring variants covering compression, extension, torsion, conical, swivel hook, drawbar, battery, wave, constant force and Belleville spring washers. As previously we feature compression, die, extension, continuous length, torsion springs and Belleville washers. Sensibly our stock spring choice covers the most commonly requested sizes but we also offer specials based on our stock range as well as tailored conical springs, swivel hook springs, drawbar springs constant force and wave springs. Completing the catalogue are several data pages which include a specifications and tolerance guide, glossary, geometric solutions, conversion data and mathematical symbols. The breadth of choice in this new catalogue confirms Lee Spring s position as the leading global supplier of springs. REDUX wave springs perform a similar function to compression springs except they take up to approximately 50% less compressed height. Manufactured in stainless steel type 17-7 PH our wave springs offer optimum performance in static or slightly dynamic applications where space is critical or where radial and axial tolerances are tight. Also new in this catalogue are constant force springs. Produced in high yield 301 stainless steel strip these springs exert a near constant Custom spring design and manufacture Springs can be designed to an almost unlimited variety of configurations and over the years Lee Spring have manufactured literally millions of custom designed springs. Custom designs are normally considered when either the performance characteristics required (e.g. environmental conditions, product life cycle, and load capabilities) or physical size and configuration requirements exceed the scope of what is available from our comprehensive stock range. 2

4 On page 164 you will find a glossary which will help explain the terminology used in specifying custom springs. Between pages 153 and 162 you will find specification forms for several types of springs along with guidelines to assist selection. We also have the capability to produce many other types of springs, washers, wire forms and stampings as well as assemblies of these products. Please contact us to discuss your particular application. As you most probably know, round wire die springs perform as well as rectangular wire form die springs. The only difference is they generally cost less! This is because it is more efficient to produce springs from round wire rather than from the rectangular wire form traditionally used. Moreover, you will enjoy the increased durability of chrome silicon steel or music wire which has always been the material of choice for steel springs. Spring kits Developed with research and development engineers, technicians and maintenance specialists in mind, our spring kits comprise a selection of different sizes and are available for standard compression, extension and torsion springs as well as instrument springs. See page 4 report the IST stated: Independent tests, undertaken at the Institute of Spring Technology (IST), have proven that Lee Spring s round wire springs have a life expectancy equal to that of rectangular wire die springs. In its Quality Our quality system is assessed by and registered with ISO 9001 BUREAU VERITAS Certification Nº 5692 Bureau Veritas to the requirements of BS EN ISO 9001:2000 certificate number This approval is the cornerstone of our service and commitment to total quality management.

Once a spring is chosen full technical details, including dimensions and loads can be accessed along with price information. Users can view and manipulate images of stock springs and download 3D or 2D CAD models in all major platforms or view and save images as jpg. or tiff. files. In terms of fatigue life, all springs completed the required 3,000,000 cycles without failure and as such no fatigue ranking of the batches A, B, C, and D (supplied) is possible. Spring materials Our stock spring range is manufactured from materials to military, aerospace and/or equivalent British or DIN standards, with design and manufacturing tolerances in accordance with British and International standards. Standard music wire and oil tempered MW springs are zinc plated, passivated and fully de-embrittled while our stainless steel springs are passivated to optimise their corrosion resistance. Springs manufactured in type 316 stainless steel offer several advantages over type type stainless. Corrosion resistance is greater, especially in chloride environments, purity levels are higher and therefore colour is more consistent. All our type 316 springs are ultrasonically cleaned as well as passivated to offer medical and food grade levels of cleanliness. Engineers Guide Our 28 page Engineers Guide to Designing & Specifying Compression, Extension and Torsion Springs has been around for so long it is considered to be a benchmark publication in the spring industry. The guide lists key design factors and provides calculations in line with the most recent British Standards applicable to spring design and materials specifications. Copies are still available free.

Price Group reference to price list. Load is the force applied to a spring that causes a deflection. DRUM is the outside diameter of a drum/shaft over which a spring fits firmly. Working Deflection is the deflection to which a spring can be safely subjected to without permanently changing its properties. Initial Deflection is the minimum deflection of a spring needed to attain the specified load. ADDITIONAL INFORMATION Manufactured from high yield 301 stainless steel strip our constant force springs exert a near constant restraining force to resist uncoiling. This natural inbuilt stress resists load at an even rate and so makes the springs suitable for use in retractor mechanisms. Common applications include counterbalance springs, car seat belt and cable retractors. Four life cycle ranges are offered: 2,500, 4,000, 13,000 and 25,000 covering loads from 1.02 to 73.42N (0.23 to 16.50lb). Mounting 11 Constant force springs are generally tightly coiled on a drum with either the free end or the drum attached to the load. This relationship can also be reversed. Important points to note: The drum diameter should be 10 to 20% larger than the inside diameter of the spring A minimum of one and one-half coils should remain on the drum at maximum extension The strip from which these springs are manufactured becomes unstable at long extensions and so should be guided to prevent twisting or kinking on recoil Idler pulleys must be larger in diameter than the natural diameter and should never be used to cause back-bending against the natural radius of curvature 10

Spring Rate change in load or force per unit of deflection. Free Length the overall length of the spring in the unloaded position ADDITIONAL INFORMATION Load at Solid Height, Solid Height and Number of Coils are all given as approximate figures because during the manufacturing process all material and engineering tolerances may result in the number of coils being adjusted, to maintain the correct spring rate. To find the load at any working length, when free length and spring rate are given, use the formula F = S x ΔL (where F is the load; S is the spring rate; ΔL is the deflection from free length). The surface area over the nominal hole diameter would be π times the diameter squared divided by 4. The resultant pressure would then be determined by dividing the calculated load by the surface area. It is general practice to avoid compressing springs to their solid height in order to achieve longer life. Therefore we recommend that compression springs should not be compressed greater than 80% of their deflective capability - except on an occasional basis. Material specifications, finishes and tolerances are detailed on page

Price Group reference to the price list Special in the S316 price group column means that springs are available but as special orders only. Solid Height Length when fully compressed. Spring Rate change in load or force per unit of deflection (See note 5). 28 Spring rates and maximum loads relate only to music wire. When using stainless steel multiply by ADDITIONAL INFORMATION Load at Solid Height, Solid Height and Number of Coils are all given as approximate figures because during the manufacturing process all material and engineering tolerances may result in the number of coils being adjusted, to maintain the correct spring rate. To find the load at any working length, when free length and spring rate are given, use the formula F = S x ΔL (where F is the load; S is the spring rate; ΔL is the deflection from free length). It is general practice to avoid compressing springs to their solid height in order to achieve longer life Therefore we recommend that compression springs should not be compressed greater than 80% of their deflective capability - except on an occasional basis. Material specifications, finishes and tolerances are detailed on page 163. Please note the spring rates at solid height and maximum load listed in the compression spring tables relate only to music wire. When choosing stainless steel multiply factors by

Ensure that the hole diameter and/or the rod diameter suitably match your application as faulty spring guidance will cause buckling and possible failure of the springs and risk damage to the die itself. Use as many springs in the die as space permits, with the least amount of deflection. Preventative maintenance of dies should be performed on a regular basis and die springs should be replaced at appropriate intervals to reduce downtime. Replace all springs in a die at the same time. This will ensure an even distribution of the applied load. Material specifications, finishes and tolerances are detailed on page

Price Group reference to the price list Maximum Extension the total overall length available before the spring will fail. Spring Rate change in load or force per unit of deflection (See note 5). 114 Spring rates and maximum loads relate only to music wire. When using stainless steel, multiply by ADDITIONAL INFORMATION To find the load at any working length, when free length, spring rate and initial tension are given, use the formula F = (S x L) + F o (where F is the load; S is the spring rate; L is the deflection from free length; F o is the initial tension). The free length of an extension spring is measured from inside the end loops. To obtain the overall length add two wire diameters to the given length. As with compression springs, in order to achieve long life and service, good design suggests that extension springs are not extended beyond 80% of their deflective capability. Material specifications, finishes and tolerances are detailed on page 163. Please note that the spring rates and maximum loads listed in the following extension spring tables relate only to music wire. When choosing stainless steel multiply the factors by

Continuous length extension springs are designed to be cut to the length required by the user. All continuous length springs are right hand wound. Number of Coils total coils in each spring. Price Group reference to the price list Stiffness change in load or force per inch of extension at the final cut length As with extension springs, in order to achieve long life and service, good design suggests that extension springs are not extended beyond 80% of their deflective capability. Material specification, finishes and tolerances are detailed on the specification page 163. Please note that the stiffness listed in the following extension spring tables relate only to music wire. When choosing stainless steel multiply the factors by To determine the spring rate per mm of extension at the final cut length use the following formula: Rate = K K = Stiffness N N = Number of coils per mm x length in mm To determine load at an extended length multiply deflection by the spring rate. VARIOUS LOOPS OR HOOKS CAN BE FORMED ON THE ENDS OF CONTINUOUS EXTENSION S. Step 1 Step 2 Step 3 Fold Spring 180 at desired length and cut. Cut shor ter than needed by onehalf the coil body diameter. Across from cut end, bend last coil up at 45 angle. To form double loop, bend last two coils up 45. Do not use heat! Twist cut end of loop into center of coil body. This may require pliers. You may have to twist past center to allow the loop to flex back. Step 4 Cut end of newly formed loop to obtain any gap needed for mounting. 138

The use of similar materials also removes the possibility of galvanic corrosion and enhances resistance to wear. Additionally, nickel helps to break down the oxide that can form on battery contact surfaces, it offers excellent corrosion resistance and is an excellent conductor of electricity. We can now offer our battery springs in silver coated beryllium copper. Beryllium copper is among the hardest, strongest, and most wear-resistant of copper alloys. Silver coating further enhances electrical and thermal conductivity. Electric conductivity is 65 to 70% that of copper while strength and fatigue resistance are comparable with higher beryllium alloys. The light silver-plating also facilitates easy soldering. Beryllium copper is corrosion resistance in many environments, and is both non-magnetic and non-sparking. PRICE Installed Height the length to which the spring will be compressed when assembled.

Unlike compression springs Belleville Spring Washers provide exceptionally high loads in restricted spaces. 150 Load flexibility can be varied by stacking the washers in various configurations (see below). Calculated Load at Flat load when the spring washer is fully compressed To minimise friction and optimise load ensure stacks of springs are guided over a shaft or in a cylinder. Series Force is equal to that of a single spring washer. Deflection amounts to that of a single spring washer multiplied by the number used. Parallel Force is equal to that of a single spring washer multiplied by the number of stacked. Combination Force is equal to that of a single spring multiplied by the number in each parallel series. Deflection is equal to a single spring washer multiplied by the number of series. 149

164 SPECIFICATIONS & TOLERANCES All the 16,500 different types of Stock springs listed in this catalogue have been selected to reflect the most popular sizes ordered. Design and manufacturing tolerances generally follow the guideline requirements of: BS :2002 and BS EN :2002 for compression springs BS :2002 and BS EN :2002 for extension springs BS :2002 and BS EN :2002 for torsion springs Springs are manufactured from materials to military, aerospace and/ or equivalent British or DIN standards. Material data Subject to the availability of material, springs may be made from either standard: wire: ASTM A228, DIN 17223, BS 5216, EN or JIS-G-3522 steel: ASTM A313, DIN 17224, BS 2056, EN or JIS-G-4314 Oil tempered MB: ASTM A229, DIN 17223, BS 2803 or EN Chrome silicon: ASTM A401, DIN 17223, BS 2803 or EN Stress relief Standard compression, die, extension and torsion springs as well as Belleville spring washers are stress relieved to remove strains induced during manufacture. Die and heavy duty compression springs are shot peened and prestressed to enhance their performance. Springs (excluding die springs) are de-embrittled at no extra cost. Finishing Our Lite Pressure 316 stainless steel springs are ultrasonically cleaned as well as passivated to offer medical and food grade levels of cleanliness. Passivation is in accordance with specification BS EN 2516:1997 or ASTM A967.

MUSIC 120 C (250 F) STAINLESS STEEL 260 C (500 F) OIL TEMPERED MB 120 C (250 F) CHROME SILICON 245 C (475 F) Note: For operation in sub-zero temperatures stainless steel must be used. Tolerances Spring manufacturing, as in many other production processes, is not exact. It can be expected to produce variations in such spring characteristics as load, mean coil diameter, free length, and the relationship of ends or hooks. The very nature of spring forms, materials and standard manufacturing processes cause inherent variations. The overall quality level for a given spring design, however, can be expected to be superior with spring manufacturers who specialise in precision, high-quality components. Normal or average tolerances on performance and dimensional characteristics may be expected to be different for each spring design. Manufacturing variations in a particular spring depend largely on variations in spring characteristics, such as index, wire diameter, number of coils, free length, deflection and ratio of deflection to free length. End Information Lite Pressure and instrument series compression springs have ends closed but not ground. Standard compression, heavy duty and die springs have ends closed and ground square (tolerance 3 ). Extension springs have full loops, random position. Direction of Helix Lee Spring Lite Pressure, compression, die and extension springs maybe left or right-hand wound at the company's discretion. If direction of wind is critical, please specify at time of ordering. Continuous length springs are right-hand wound. Note: Other special finishes may be supplied on request at additional cost. 163

165 164 Active coils (effective coils, working coils). The coils of a spring that at any instant are contributing to the rate of the spring. Buckling. The unstable lateral distortion of the major axis of a spring when compressed. Closed end. The end of a helical spring in which the helix angle of the end coil has been progressively reduced until the end coil touches the adjacent coil. Compression spring. A spring whose dimension, in the direction of the applied force, reduces under the action of that force. Compression test. A test carried out by pressing a spring to a specified length a specified number of times. Creep. The change in length of a spring over time when subjected to a constant force. Deflection. The relative displacement of the ends of a spring under the application of a force. Elastic deformation. The deformation that takes place when a material is subjected to any stress up to its elastic limit. On removal of the force causing this deformation the material returns to its original size and shape. Elastic limit (limit of proportionality). The highest stress that can be applied to a material without producing permanent deformation. End fixation factor. A factor used in the calculation of buckling to take account of the method of locating the end of the spring. Extension spring. A spring whose length, in the direction of the applied force, increases under the application of that force. Fatigue. The phenomenon that gives rise to a type of failure which takes place under conditions involving repeated or fluctuating stresses below the elastic limit of the material. Fatigue limit. The value, which may be statistically determined, of the stress condition below which material may endure an infinite number of stress cycles. Fatigue strength (endurance limit). A stress condition under which a material will have a life of a given number of cycles. Fatigue test. A test to determine the number of cycles of stress that will produce failure of a component or test piece. Finish. A coating applied to protect or decorate springs. Free length. The length of a spring when it is not loaded. NOTE. In the case of extension springs this may include the anchor ends. Grinding. The removal of metal from the end faces of a spring by the use of abrasive wheels to obtain a flat surface which is square with the spring axis. Helical spring. A spring made by forming material into a helix. Helix angle. The angle of the helix of a helical coil spring. Hysteresis. The lagging of the effect behind the cause of the effect. A measure of hysteresis in a spring is represented by the area between the loading and unloading curves produced when the spring is stressed within the elastic range. Index. The ratio of the mean coil diameter of a spring to the material diameter for circular sections or radial width of cross section for rectangular or trapezoidal sections. Initial tension. The part of the force exerted, when a close coiled spring is axially extended, that is not attributable to the product of the theoretical rate and the measured deflection. Inside coil diameter of a spring. The diameter of the cylindrical envelope formed by the inside surface of the coils of a spring. Loop (eye, hook). The formed anchoring point of a helical spring or wire form. When applied to an extension spring, it is usually called a loop. If closed, it may be termed an eye and if partially open may be termed a hook. GLOSSARY Modulus of elasticity. The ratio of stress to strain within the elastic range. NOTE. The modulus of elasticity in tension or compression is also known as Young's modulus and that in shear as the modulus of rigidity. Open end. The end of an open coiled helical spring in which the helix angle of the end coil has not been progressively reduced. Outside coil diameter. The diameter of the cylindrical envelope formed by the outside surface of the coils of a spring. Permanent set (set). The permanent deformation of a spring after the application and removal of a force. Pitch. The distance from any point in the section of any one coil to the corresponding point in the next coil when measured parallel to the axis of the spring. Prestressing (scragging). A process during which internal stresses are induced into a spring. NOTE. It is achieved by subjecting the spring to a stress greater than that to which it is subjected under working conditions and higher than the elastic limit of the material. The plastically deformed areas resulting from this stress cause an advantageous redistribution of the stresses within the spring. Prestressing can only be performed in the direction of applied force. Rate (stiffness). The force that has to be applied in order to produce unit deflection. Relaxation. Loss of force of a spring with time when deflected to a fixed position. NOTE. The degree of relaxation is dependent upon, and increases with, the magnitude of stress, temperature and time. Safe deflection. The maximum deflection that can be applied to a spring without exceeding the elastic limit of the material. Screw insert. A plug screwed into the ends of a helical extension spring as a means of attaching a spring to another component. The plug has an external thread, the diameter, pitch and form of which match those of the spring. Shot peening. A cold working process in which shot is impacted on to the surfaces of springs thereby inducing residual stresses in the outside fibres of the material. NOTE. The effect of this is that the algebraic sum of the residual and applied stresses in the outside fibres of the material is lower than the applied stress, resulting in improved fatigue life of the component. Solid length. The overall length of a helical spring when each and every coil is in contact with the next. Solid force. The theoretical force of a spring when compressed to its solid length. Space (gap). The distance between one coil and the next coil in an open coiled helical spring measured parallel to the axis of the spring. Spring seat. The part of a mechanism that receives the ends of a spring and which may include a bore or spigot to centralise the spring. Stress (bonding stress, shear stress). The force divided by the area over which it acts. This is applied to the material of the spring, and for compression and extension springs is in torsion or shear, and for torsion springs is in tension or bending. Stress correction factor. A factor that is introduced to make allowance for the fact that the distribution of shear stress across the wire diameter is not symmetrical. NOTE. This stress is higher on the inside of the coil than it is on the outside. Stress relieving. A low temperature heat treatment carried out at temperatures where there is no apparent range in the metallurgical structure of the material. The purpose of the treatment is to relieve stresses induced during manufacturing processes. Variable pitch spring. A helical spring in which the pitch of the active coils is not constant.
