Description

 With the Crossed roller bearing, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90°V groove, separated from each other by a spacer retainer.  This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the Crossed Roller bearingachieves high rigidity and the precision can reach up to P4.P2,despite the minimum possible dimensions of the inner and outer rings,it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines

Rotation accuracy

The spacer retainer fitting among cross-arrayed rollers prevents rollers from skewing and the rotation torque from increasing due to friction between rollers. Unlike conventional types using steel sheet retainers, the crossed roller bearingdoes not cause displacement or locking of rollers and provides a stable rotation torque. Since the inner and outer rings are designed to be separable, the bearing clearance can be adjusted. In addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.

 

RU178X bearing: The inner ring has through-holes, while the outer ring has couterbore holes.

 

RU178G bearing: The inner and outer rings’ counterbore holes are oriented in the opposite way.

 

Customized bearings

We can design the bearing according to your required types,sizes and application.
If you have drawing and datasheets, it is better. We will produce the bearing according to your drawing and datasheet totally.

Receiving

Customers suggested unpack, inspect and sign for the goods when you receive bearings. If you find any problem, please contact us.

Issues occurred during use

Bearing is not only related to its own quality, but also related to the installation method, load, speed, temperature and daily working hours.
If there is any problem in the use of bearing, please provide us with the above information in time so that our technicians can make an accurate and effective analysis.
