RB Crossed Roller Bearings

RB crossed roller bearing characteristics:

1. High precision: P4 precision, P2 precision.

2. High rigidity: This series bearing have preload.

3. High load: This series bearing can bear double-direction axial load, radial load and tilting moment.

4. Small size: This series bearing can save space for machine tools.

RB crossed roller bearing series (outer ring division type with inner rotating), this type is the basic type of crossed roller bearings. The outer rings have two parts, and the inner ring is one integer. The type is well applied to the situation which need high rotation accuracy on inner ring. For example, it is suitable for the rotary part of the indexing table of the tools machine.
