RB series crossed roller bearing
RB 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.

Crossed roller bearings operate on the principle of linear contact between the rollers and raceways. The rollers roll between the raceways, transmitting loads in all directions, including axial, radial and moment loads. The linear contact between the rollers and raceways ensures high rigidity and precision.
We focus on high-precision Slewing bearings, cross roller bearings, and pinions with diameters from 50mm to 8000mm. Our team brings extensive technical experience to the bearing industry.
