RE20025/20030/20035 crossed roller bearing (THK Outer ring rotation type)

详情

Model RE (Separable Inner Ring, Type for Outer Ring Rotation)

This new model is based on the design of principal of the RB, Having the same major dimensions as model RB, its inner ring is separable while the outer ring is integrated with the main body，this model is used in locations where the rotation accuracy of the outer ring is required.

Product Feature

High Rotation Accuracy The spacer retainer fitting among cross-arrayed rollers prevents rollers from skewing and the rotational torque from increasing due to friction between rollers. Unlike conventional types using steel sheet retainers, the Cross-Roller Ring does not cause unilateral contact of roller or seize. Thus, even under a preload, the Cross-Roller Ring provides stable rotation.

Application

it is optimal for applications such as joints and swiveling units of industrial Robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, Medical equipment, measuring instruments and IC manufacturing machines

E. Installation & Cautions
 

1. Inspect the parts before installing:Clean bearing bracket,main axle or other parts to remove dirt or grease.
2. Place the bearing into the bearing bracket and main axle:To match the design clearance ,keep the bearing horizontal and insert the bearing into the bearing bracket or axle.If it is hard to install,use a rubber hammer to slightly hit every part of the bearing,so that the bearing can be attention to the hitting force is too large.Afterwards,the matching status of bearing and basic face can be examined by checking the noise.For a interference fit,use heating or cooling to expand or shrink the parts for ease of installation. Be sure the bearing temperature does not exceed *0℃ . If the split inner or outer ring is acentric, please loosen the blots slightly and rotate the monolithic ring to adjust the concentricity of split ring, so that the bearing can be fit in the bracket.
3. Install the mounting disc:Place the mounting disc onto the bearing and align the screw holes, Screw all the bolts in the holes first and follow the orders show in below diagram when tightening bolts in diagonally opposite sequence,Do not tighten bolts randomly.

Cautions:
1.The normal operating temperature of Crossed roller bearing is ****0℃, If it is over this range,please contact BYC.
2.If a foreign substance enters inside the bearing structure, the rotation route of the roller may be damage, or the bearing may fail.Please clean the bearing by refill the lubricant grease.
3.Please do not remove or apply force to the bolt and nut of the split bearing.
