Cross Roller bearing CRB25040 used in heavy machinery

Structure and Features :

With the Cross-Roller Ring, cylindrical rollers are arranged 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 Cross-Roller Ring achieves high rigidity 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.

Installation Procedure: 

1.Thoroughly clean the housing and other parts to be installed, and check to determine if deburring is required. 

2.Since the Crossed Roller bearing is a thin-wall bearing type and therefore tends to misalign when it is installed, in case of this situation,gradually drive the product into the housing or onto the shaft by gently hitting it with a plastic hammer, while keeping the product horizontal. Taking care, continue to hammer until it fully contacts the reference surface. 

3.Place the presser flange onto the Crossed Roller bearing . Rock the flange several times to match the bolt holes. 

4.Insert the presser bolts into the holes.  Manually turn the bolts and make sure they do not display skewing caused by misalignment of the holes. 

5. As is shown in the pictures below:Tighten the presser bolts in three to four steps from light to full tightening byrepeatedly securing the bolts in diagonal order.When tightening the separable inner or outer ring, slightly turning the integral outer or inner ring will correct the dislocation between the ring and the body.      The main products of our company are crossed roller bearings, YRT rotary table bearings, crossed tapered roller bearings. The leading products include crossed roller bearing RB, RE, RU,RA,CRBC, CRBH, XSU, SX series, rotary table bearings YRT, YRTS,YRTM,ZKLDF series, crossed tapered roller bearing XR series, almost whole range of precision bearings. The accuracy grades are P5, P4, P2, and the size of inner ring are ranging from Φ50mm --- Φ1300mm. Our products are optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines,mainly to replace the imported bearings. Also, we can design,choose and manufacture  non-standard,large size precision bearings as customer requested.
