Product Details

RB13015 cross roller bearing RB13025 crossed bearing

Product Description

With the CrossRoller Ring, 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 CrossRoller 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.

High Rotation Accuracy

The spacer retainer keeps rollers in their proper position, thereby preventing them from skewing. This eliminates friction between rollers, and therefore secures 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.

Easy Handling

The inner and outer rings, which are separable, are secured to the Cross Roller Ring 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 the Cross-Roller Ring.

Skewing Prevention

The spacer retainer fitting among crossarrayed rollers prevents rollers from skewing and the rotation torque from increasing duefriction between rollers. Unlike conventional types using steel sheet retainers, the CrossRoller Ring does not cause displacement or locking of rollers and provides a stable rotation torque.
