Product Features

Since the mounting holes are provided, this model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure. This model can be used for both inner-ring rotation and outer-ring rotation.

Series Introduction

XSU special type is a bearing with integrated inner and outer ring. It is used in cases where high rotational accuracy of both the inner- and outer rings is required.

Applications

Industrial Robotic arm, Reducer drive
Precision Turntable, CNC rotary table
Rotation part of Machine tools
Inspection instrument, Medical equipment
Aviation equipment, Military radar etc

Product Features

The structure of SX series crossed roller bearings is similar to RB series, the outer ring is separable and connected with three locating rings. While the inner ring is integrated with the main body. This model is used for occasions where the rotation accuracy of the outer ring is required.

Series Introduction

SX standard type is a bearing similar to RB standard type. The two separable outer rings are connected by locking ring.

Applications

Industrial Robotic arm, Reducer drive
Precision Turntable, CNC rotary table
Rotation part of Machine tools
Inspection instrument, Medical equipment
Aviation equipment, Military radar etc

Product Features

LYSYM 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

RU special type is a bearing with integrated inner- and outer ring. It is used in cases where high rotational accuracy of both the inner- and outer rings is required.

Applications

Industrial Robotic arm, Reducer drive
Precision Turntable, CNC rotary table
Rotation part of Machine tools
Inspection instrument, Medical equipment
Aviation equipment, Military radar etc

Product Features

LYSYM 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

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.

Applications

Industrial Robotic arm, Reducer drive
Precision Turntable, CNC rotary table
Rotation part of machine tools
Inspection instrument, Medical equipment
Aviation equipment, Military radar, etc

Product Features

RA Cross roller bearings are designed to offer an more compact type of RB series crossed roller bearings. The bearing features all attributes of RB series crossed roller bearings while conserving space with thin inner and outer ring. Because of its vertical arrangement of rollers in a 90°V, the bearing is capable to carry loads in all directions at the same time: radial,axial and moment loads. Thus, the bearing housing and presser flange can be lightweight. It is optional for areas where the swiveling units need to be lightweight. Combined with its high rigidity, it can be applied to the joints and rotating parts of industrial robots, rotary tables of machining centers, medical equipment, measuring instruments, rotating parts of manipulators, precision rotary tables, etc.

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

Product Features

The inner ring and outer ring of the CRBH series crossed roller bearings are all integrated structure, their overall sizes are completely same with RB and RE series crossed roller bearings, but its outer ring have hole type structure for installing bearing rollers, so both the inner ring and outer ring can achieve high rotation accuracy, thus both the bearing inner ring and outer ring is available to rotating.

CRBH series crossed cylindrical roller bearings is mainly used for: rotation part of the machine tools, CNC rotary table, medical equipment, aviation equipment, precision turntable, etc.
