Features
Cross roller bearings are two columns of cylindrical rollers arranged vertically across each other through nylon isolation blocks on the 90-degree v-shaped raceway, so cross roller bearings can withstand radial load, axial load and torque load.
The dimensions of the inner and outer rings are miniaturized, the extremely thin form is close to the limit of the small size, and has high rigidity, the cross roller bearing precision can reach P2 level.

The cross roller bearing is suitable for precise applications requiring multi-directional bearing, such as robot arm, precision turntable, etc.
The bearing itself is designed with negative clearance, so the bearing is rigid enough to withstand large loads and has high precision (basically, it beats between 0.001mm and 0.01mm, and the bearing precision is above P5).
The selection of cross roller bearing is mainly to consider the mounting mode and size of the bearing, which can be divided into the following two types:
1. The cross roller bearing without installation hole has a thinner wall thickness, which is suitable for small installation space. The bearing needs to be pressed on the equipment with flange plate. The specific difference of RB/RE/CRBH/SX/RA type is as follows
2. The inner and outer rings of the cross roller bearing with mounting holes are designed with mounting holes for convenient installation and use. They are widely used in robots and turntables.
