7 NIKOR 1. Recirculating Ball Bearing, rawn shell esign, compact type, series KH The inear Recirculating Ball Bearings KH are compose of a steel rawn shell, mae of case harene steel, a retainer mae from engineere resin an precision balls. The rawn shell has pockets esigne to allow the recirculation of the balls. This bearing type can only be use for linear movement an oes not allow rotational movements. 1.1 Seals The linear bearings of KH type are available in two ifferent variants. ithout seals: KH ith contact seals: KH..PP The seals have the ual function to prevent ingress of contaminants an the retention of lubricants in the bearings. 1.2 ubrication inear bearings type KH are supplie coate with rust inhibiting oil. inear bearings type KH..PP are supplie package with lithium soap grease. 1.3 Mounting tolerances The table below shows the tolerances to be use for a proper bearing installation. They insure a precise an smooth motion. 1. Assembly inear bearings type KH are assemble with a light press fit. This insures not only the retention of the bearing but also the proper rouning of the unit. A proper fitting shoul be performe with the help of a mounting arbor as shown in Fig. 1. Table 1.1 Recommene mounting tolerances Fig.1 Housing material General application Vertical operation Precision application Housing tolerance Shaft tolerance Housing tolerance Shaft tolerance Steel/cast iron H7 h H i Aluminium/alloy K7 h K i 2. inear Recirculating Ball Bearing precision series type ME MB NIKO inear Recirculating Bearing type ME an MB are compose by a cylinrical outer ring, by a cage that retains the balls, by two en rings to retain the cage an/or, when require, contact seals. All of the components are esigne an assemble to optimize the unit performance. The outer ring is suitably harene to provie the longest possible life expectancy. The cage mae of steel or engineere resin, epening upon the type of bearing selecte, provie the retention an allow the proper recirculation of the balls.

8 NIKOR 2.1 Characteristics of linear bearings type ME High rigiity inear bearings with steel outer ring offer high rigiity ue to the large number of balls in contact. The units can be supplie with a steel cage an, when low weight is require, with resin cage Ease of assembly The stanar units can carry loa in every irection. The large variety of housing units an shaft supports allow simple an easy mounting Ease of replacement These units follow internationally recognize bounary an are therefore imensionally inter changeable with competitive units. Replacement ue to wear or amage is quick an simple Complete range The NIKO range of proucts is quite broa. The characteristics can be summarize as follows: A) Close type stanar version B) Ajustable type These units have a longituinal slot tha allows the reuction of the operating clearance an the optimization of the unit rigiity. C) Open type These units have an opening that correspons to a single recirculating channel ( 0 to 100 eg ). These units are use in conjunction with long shafts that are typically supporte along the entire length to reuce the elastic eflection. hen mounte in a suitable housing, the units allow the ajustment of the operating clearance. D) Flange type These units have a flange on the outer ring to allow the mounting without conventional housings. 2.2 Seals inear bearings ME an MB can be supplie in the following versions: ithout seals ME/MB ith contact seals ME..UU/MB..UU The seals have the following functions: Prevent the ingress of contaminants Retain the lubricant in the bearing In some applications, it may be necessary to use aitional seals to prevent grease migration an thus prolong the maintenance interval. 3. inear Recirculating Ball Bearing precision series type ME MB 3.1 ubrication inear bearings type MEMB are supplie coate with rust inhibiting oil. inear bearings type ME..UU/MB..UU are supplie package with lithium soap grease. 3.2 Mounting tolerances The bearing assembly shoul be performe as to insure operation with aequate clearance. Unsuitable operating clearance coul lea to poor running performance or lower than expecte urability. The operating clearance of the ajustable or open version of the linear bearings can be ajuste by elastically eforming the outer ring. The suitable mounting tolerances for the mating components are shown in table 3.1. Note: The operating clearance is application epenent an coul be zero or negative (preloa). In the latter case the friction as well as the smooth running shoul be checke for suitability. 7

The installation of the units is not particularly ifficult, though precaution shoul be observe to avoi potential amages to the unit. Direct pressing onto the cage retaining rings shoul be avoie. A suitable tool shoul be use (Fig. 2) to provie pressure on the rim of the outer ring. Once the bearing is mounte in the housing, the assemble unit shoul be installe onto the shaft paying attention not to score the shaft or to pop the balls from the bearing. hen two shafts assemblies are assemble in a parallel assembly, the parallelism between the shafts shoul be checke to insure smooth running. The mounting examples shown in Fig. 3 through 7 shoul be use as guielines to esign an select the suitable bearings an support units.. oa ratings Dynamic loa rating C The ynamic loa rating C is a loa of constant magnitue uner which 90% of a statistically significant number of apparently ientical bearings woul reach a theoretical life of 0 km without the apparent appearance of metal fatigue. Static loa rating Co The static loa rating Co is efine as the loa that woul cause a permanent eformation equal to 1/10,000 of the ball iameter at the most stresse contact point..1 ife of a inear Recirculating Ball Bearing Repeate stresses onto the contact surfaces coul lea to material fatigue. This will lea to the appearance of surface pitting. The life of the unit is efine as the uration before the appearance of pitting.

The theoretical life of a linear bearing is affecte by the loa an by the operating conitions ( temperature, vibration, shocks, loa istribution, etc.). In such cases the theoretical life is calculate with the help of equation 2. = ( f H. f T. f C.

12 NIKOR. Friction inear Recirculating Ball Bearings have a very low static coefficient of friction, virtually ientical to the ynamic coefficient of friction. This results in low an uniform motion in any conition of loa an spee without sickslip. u F =. + f...() F = Friction force [N] U = Friction coefficient [] f = Seal rag [N] w = oa [N] The magnitue of the friction force is affecte by several factors. The type of bearing, the operating conitions, the type an quantity of the lubricant, the presence or lack of seals all impact the overall frictional behavior. Stanar seals can a between 2 an Ntothe overall friction force. The magnitue of the coefficient of friction epens upon the operating conitions such as loa, moments an/or preloa. Table.1 shows the ynamic coefficient of friction for each type of bearing uner normal operating conition (P/C =0.2) an proper assembly.
