Company Profile

Precision Equipment Cross Roller Bearings High Load Capacity CRBH Series

CRBH Series Cross Roller Bearings

The CRBH series (inner and outer rings as a whole, ultra-thin) requires installation due to its ultra-thin design and the absence of mounting holes on the outer and inner rings for fixing the flange and support seat. In addition, since both the outer and inner rings are integral structures, the installation does not affect the performance, so it is possible to achieve stable rotational accuracy and torque, which is suitable for situations in which the outer and inner rings rotate but require miniaturization in size.

Crossed roller bearings are high-precision, high-rigidity rolling bearings, and their structural design is particularly suitable for bearing complex loads, including radial, axial and overturning moments. Crossed roller bearings are widely used in high-demand fields such as mechanical arm joints, industrial robots, machine tool rotary tables, and precision rotating devices.
