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.
RA thin type is a small and light weight bearing with a very thin wall thickness. The miniaturized design of thin-walled size is helpful for the light and thin design of related structures. The overall structure of the inner ring is more suitable for occasions with high rotation accuracy of the inner ring, and the stable rotation accuracy reaches microns; it is suitable for precision testing instruments, robot joints, and direct drive torque. Motors, high-precision turntables and other applications requiring high precision and high rigidity.

RA series Cross roller bearing


(Separable Outer Ring Type for Inner Ring Rotation)


Product Features

HGB 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.


Series Introduction

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.


Applications

  • Industrial Robotic arm, Reducer drive

  • Precision Turntable, NC rotary table

  • Rotation part of Machine tools

  • Inspection instrument, Medical equipment

  • Aviation equipment, Military radar, etc
