XSU Series Crossed Roller Bearing

XSU series Cross roller bearing|CNC machine tool bearings|precision INA type bearing

(Integrated Inner/Outer Ring Type)
Product Features:
CXB 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 :
XSU special type is a bearing with integrated inner and outer ring. It is being used

in cases where high rotational accuracy of both the inner- and outer rings is required.
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
