China Efant Luoyang High Precision Bearing Rb3010 Cylindrical Cross Roller Bearing, Find details about China Cross Roller Bearing, Cross Roller Bearing Use for Industrial Robot from Efant Luoyang High Precision Bearing Rb3010 Cylindrical Cross Roller Bearing
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.
RB CROSS ROLLER BEARING SERIES FEATURE:
Being the basic model of the Cross-Roller Ring, despite the minimum possible dimensions of the inner and outer rings, its outer rings are 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.
