CRB Series Crossed Roller Bearings

CRB series crossed roller bearing series (Split outer ring, with inner ring rotating).CRB series crossed roller bearing series is the primary type of cross roller bearing. Its structure is two split outer rings (connected by bolt or unique rivet, integral design of inner ring), so the inner ring has high rotation accuracy. The integrity of the inner ring is more suitable for high precision of inner ring rotation, and stable rotation accuracy reaches micron level. For example, the rotating position of the machine tool indexing table, the internal rotor drive motor, and so on.
