The thin precision crossed roller bearing
 The thin precision crossed roller bearing

The thin precision crossed roller bearing 

The thin precision crossed roller bearing is provided with three series, including the separable outer ring types and the single-split types. The separable outer ring types are compact with extremely thin inner rings and outer rings of RB type. It is applicable in the low weight and compact design, such as the rotating part of the robots and mechanical arms. The single-split types are designed with the same dimensions as RA types. Thanks to the notch in the outer ring, it achieves high rigidity. It is an ideal product in the outer ring rotating applications.

RA series Cross roller bearing .RE It is being used in cases where the high rotational accuracy of the outer ring 

is required.


RA series Cross roller bearing 


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


RB series:

RB standard type is a bearing with thinnest possible inner and outer rings because

 the outer ring is split while the inner ring is integrated into the main body.

 It is being used in cases where a high rotational accuracy of the inner ring 

is required.



RE Series:


RE standard type is an innovative bearing based on the design of the RB standard type

 bearing. The inner ring is separable while the outer ring is integrated into the main

 body. It is being used in cases where the high rotational accuracy of the outer ring 

is required.
