RB5013 crossed roller bearing |thin section bearing|50*80*13mm

(Separable Outer Ring, Type for Inner Ring Rotation)

RB5013 crossed roller bearing is the basic model of the Cross Roller bearing, despite the minimum possible dimensions of the inner and outer rings, its outer ring is separable while the inner ring is integrated with the main body.  This model is used in locations where the rotation accuracy of the inner ring is required. http://bycbearing.en.alibaba.com

Structure features of  RB5013 crossed roller bearing:

With the Cross 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:http://lyboying.goepe.com

The spacer retainer fitting among RB series crossed roller bearing 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 Cross roller bearing does 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.

Usage characteristics

Theouter rings, which are separable, are secured to RB5013 Cross Roller bearing body after the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other.  Thus, it is easy to handle the rings when installing this type.
