With the cross roller bearing ,cylindrical roller are arranged crosswise ,with each roller perpendicular to the adjacent roller ,in a 90°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 and the precision can reach up P5 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 table of machining centers .precision rotary tables,medical equipment,measuring instruments and IC manufacturing machines.

Application of RB5013 Cross Roller Bearing on the rotary table of machine tools. With reference to similar foreign products and combined with its own characteristics, it has developed a series of cross roller bearings suitable for use on the rotary table of machine tools.

The low carbon steel material of RB5013 Cross Roller Bearing has too low hardness after annealing, which will cause sticking during cutting and poor cutting performance. Increased hardness by normalizing can improve cutting performance. Some medium carbon structural steel parts can be normalized. Instead of quenching and tempering, the heat treatment process is simplified.

The main parameters are as following:
