RB Series

RB Series Crossed Roller Bearings

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.


1. Structure
RB Standard Type (separable Outer Ring for Inner Ring Rotation)
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.

2. Features
High precision: precision at P5,P4.
High rigidity: These ball bearings are with preload.
High load capacity: these kind of high precision bearings usually has the capability to support axial load, radial load, and tilting load.
Small volume: These cross roller bearings can save space for the machine.


3. Application
•Industrial Robotic arm,Reducer drive
•precision Turntable,NC rotary table
•Rotation part of Machine tools
•Inspection instrument,Medical equipment
•Aviation equipment,Military radar etc
