Crossed Roller Bearing (CRB Series)

Product Description

The crossed roller bearing is one of our distinctive products for substituting the imported bearings. The every second roller is at right angles to its neighbouring rollers in the raceway between the outer ring and the inner ring, and that makes the bearing very compact. It can accomodate axial, radial and overturning moment loads acting either singly or in combination and has as 4 to 5 times rigidity as other bearings. The crossed roller bearing is highly precision in rotation and simple in Mounting.

SZY light-cylindrical roller bearings is the characteristic development product of our company to replace imported products. The bearing use in he flexible operation of the key components of military radar, to achieve high-precision, negative clearance, low friction torque activated technology related requirements.

It has also been used in Harmonic Drive, inside and outside of the bearings have positioning holes, double-thread linking the outer ring, the inner ring as a whole; Rollers are 90°, 1: 1 cross-arranged, the overall high-strength steel stamping maintain -. It has high capacity, high torque rigidity, a lower start friction torque characteristics.

It has also been used in the rotary stage of Yasukawa Robot base, size of 480 mm diameter, high precision bearings processing, and rolling of the Rotary flexible, which is up to positioning requirements of robot arm. Bearing also features a sealed, and played a good fat and prevent leakage into the external debris bearings.
