Cross roller bearing RB 4510 for speed reducer - THB Bearings

Structure and Character

Cross Roller Bearing, because of its vertical arrangement of cylindrical roller with a 90°V groove through the

separate spacers in the deep groove rolling surface. This design allows just one bearing to receive loads in all

directions including radial, axial and moment loads.

At the same time, cross roller bearing is a lightweight, compact type with thinnest possible inner and outer rings,

especially for the thinnest, with high rigidity. It is optimal for application 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.

Excellent Rotation accuracy

The spacers fitting among cross arranged rollers prevents rollers from skewing and the rotation torque from

increasing due to friction between rollers. The spacers keeps rollers in their proper position, thereby preventing them

from skewing. It does not cause unilateral contact of roller or locked rollers. Since the inner and outer rings are

designed to be separable, the bearing clearance can be adjusted. In addition, a preload can be applied. These

feature enable accurate rotation.

Easy Handling

The inner and outer rings, which are separable, are secured to the body after being installed with rollers and spacers.

Therefore, it is easy to handle the rings when installing the Cross Roller Bearing.
