Цилиндрический роликовый подшипник миниатюрный для аппаратного подшипника RA15008

Cylinder roller bearing miniature roller bearing for hardware bearing RA15008 16013

1. Structure features 

 With the Cross Roller Bearing, cylindrical rollers arc 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 Cross-Roller Ring achieves high rigidity and the precision can reach up to 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 tables of machining centers, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.

2.Rotation accuracy

The spacer retainer fitting among 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 docs not cause displacement or locking of rollers and provides a stable rotation torque. Since the inner and outer rings arc 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.

3.Usage characteristics

Based on model RB,this model is a light and compact type with the thinnest possible inner and outer rings.It is optimal for location where weight reduction and downsizing are required,such as the hand sweiveling unit of robots and manipulators.
