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.
