RB50040 Crossed Roller Bearing
The outer ring of the RB50040 crossed roller bearing is divided into two parts. After the rollers and cages are installed, they are fixed in place, so the installation operation is very simple. The inner ring is a one-piece design, suitable for parts that require high rotation accuracy of the inner ring.

How to improve the installation accuracy of crossed roller bearings?
According to the load direction of the RB cross roller bearing and which ring is the rotating part, the load borne by each ring can be divided into the rotating load, static load, or non-directional load. The ferrule bearing rotating load and non-directional load should adopt a static fit (interference fit), and the ferrule bearing static load should adopt a transition fit or dynamic fit (clearance fit). When the bearing is heavily loaded or subjected to vibration or shock load, its interference must be increased. When using hollow shafts, thin-walled bearing boxes, or light alloy or plastic bearing boxes, the amount of interference must also be increased. When it is required to maintain high rotation, high-precision bearings must be used, and the dimensional accuracy of the shaft and the bearing box must be improved to avoid excessive interference. If the interference is too large, the geometrical accuracy of the shaft or the bearing housing may affect the geometrical shape of the bearing ring, thereby impairing the rotation accuracy of the bearing.
