Table rosse Bearing Type Features of Super Slim Type rosse Bearing RBT Slim Type rosse Bearings Type Rigiity Type rosse Bearings RBH Stanar Type rosse Bearings RB,RB Super Slim Type rosse Bearings RBT Mounting Hole Type Rigiity rosse Bearing RBF Rigiity Type rosse Bearings Both inner an outer rings have a soli one-piece construction. Therefore, high accuracy an high rigiity are achieve, an mounting errors can be minimize. As separators are incorporate between the cylinrical rollers for smooth rotation, these bearings are suitable for applications where rotational spee is comparatively high. Stanar Type rosse Bearings The outer ring is mae of two split pieces, which are bolte together to prevent separation uring transportation or mounting. So, hanling is easy.

Therefore, these bearings minimize power consumption an operating temperature rise of machinery an increase the overall efficiency of machines. The rotational torque is affecte by many factors, but the following formula can be use expeiently. D pw T = μp r where, T : Rotational torque, μ : Friction coefficient (Approx..) P r : Static equivalent raial loa, D pw : Pitch circle iameter, + D D pw Lubrication ( ) These bearings are generally lubricate with grease. Grease is supplie through the clearance between the inner ring an the outer ring. Grease specification is shown in Table, ALVAIA GREASE EP (SHOWA SHELL SEKIYU K.K) is prepacke as the lubricating grease. For bearings without prepacke grease, supply grease or oil for use. Operating without grease or oil will increase the wear of the rolling contact surfaces an cause a short bearing life. When using a special grease, carefully examine the grease properties an contents such as base oil viscosity an extreme pressure aitives. In this case, please contact.

When an oil hole is require on the outer ring, attach "-OH" before the clearance symbol in the ientification number. When an oil hole an an oil groove are require on the outer ring, attach "-OG" at the same place in the ientification number. For an oil hole on the inner ring, attach "/OH", an for an oil hole an an oil groove on the inner ring, attach "/OG", at the same place in the ientification number.

9 Example When the inner ring has oil holes RB / OH Operating Temperature Range The operating temperature range for rosse Bearings is +. However, the maximum allowable temperature for types with separator an with seal is +, an + when they are continuously operate. Mounting When the rigiity of the mounting parts is not sufficient, stress concentration will occur at the contact area between the rollers an raceways, an the bearing performance will be eteriorate significantly. Therefore, it is necessary to carefully examine the rigiity of housing an the strength of fixing bolts when a large moment will be applie. The shouler height iameters ( a an D a ) that are relate to mounting shoul certainly satisfy the values shown in the imension tables. When these imensions are incorrect, eformations of inner an outer rings will occur an the bearing performance will be eteriorate remarkably.. For other Mounting Hole Type Rigiity rosse Bearing Fig. Mounting example Oil holes In inner ring Example When the outer ring has a single oil hole RB - OH Oil hole In outer ring The inner an outer rings shoul be securely fixe in the axial irection by using fixing plates, etc. Recoene thickness of the fixing plate is / or more of the bearing with B. The imensions in the axial irection of the housing bore an the fixing plates shoul be etermine to get a secure fixing while consiering the imension of bearing with which is given a minus tolerance. (See Fig.) The epth of the housing bore is recoene to be equal to or larger than the bearing with. Separation prevention bolts for the outer ring of Stanar Type rosse Bearings are provie to prevent separation of two halves of the outer ring uring transportation or mounting. When mounting, they shoul be loosene slightly. Rigiity Type rosse Bearings, Super Slim Type rosse Bearings an Slim Type rosse Bearings have a plug for hole for inserting rollers. When mounting the bearings, locate the plug at a position that is not inclue in the maximum loaing zone. The plug location can be foun by the pin that is at the sie of the outer ring.. For Mounting Hole Type Rigiity rosse Bearing Fig. Example of irect mounting to the mating surface of Mounting Hole Type Rigiity rosse Bearing Mounting Hole Type Rigiity rosse Bearing can be mounte irectly to the mounting surface by fixing bolts. (See Fig.) Fig. Example of mounting to the housing of Mounting Hole Type Rigiity rosse Bearing If large number of raial loa an/or moment is expecte, it is recoene to prepare flange part. (See Fig.) Mounting Hole Type Rigiity rosse Bearing has a plug for hole for inserting cylinrical rollers. When mounting the bearings, locate the plug at a position that is not inclue in the maximum loaing zone. The plug location can be foun by the pin that is at the sie of the outer ring. Tightening torque of mounting bolts The stanar torque values for Mounting Hole Type Rigiity rosse Bearings mounting bolts are shown in Tables. When machines or equipment are subjecte to severe vibration, shock, large fluctuating loa, or moment loa, the bolts shoul be tightene with a torque. to. times higher than the stanar torque values shown. When the mating member material is cast iron or aluminum, tightening torque shoul be lowere in accorance with the strength characteristics of the material. Please o not tighten with too much torque as abnormal frictional torque or short life may occur. Table Tightening torque of mounting bolts Bolt size Tightening torque m M.. M.. M..9 M. Above values are for arbon steel bolt (Strength ivision.9) Double Row Angular ontact Bearing We provie Double Row Angular ontact Bearing inicate to the right to orer. If neee, please contact. Double Row Angular ontact Bearing has a large number of cylinrical rollers with a large contact area with a raceway an an excellent loa capability, between the inner an outer rings arrange in two rows of raceways. This unerpins further higher rigiity an lower torque than Rigiity Type rosse Bearings. The mounting holes in both inner an outer rings facilitate installation to your machines an equipment. Further, the integrate structure (non split) constructe in both inner an outer rings can avoi an installation error, which yiels extra-high-rigiity an highaccuracy guiing performance without being affecte by other peripheral structures such as a housing an a fixing plate.
