RA Series Description:

THB Crossed roller bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads. 


THB RA Thin Type(separable Outer Ring for Inner Ring Rotation) 


THB RA thin type is a small and light weight bearing with a very thin wall thickness. It carries heavy loads. Therefore, the bearing housing and pressure flange can be light weight. It is being used in rotary locations such as in robot hands. The outer rings of the RA thin type are separable and fixed by special rivets.


UU means with seals at both sides;

CC0/C0: radial clearance group

Precision: P2, P4, P5, P6
