RB Series Crossed Roller Bearings

RB series crossed roller bearing is the basic model of crossed roller bearing. It has a detachable outer ring and a united inner ring. So it is widely used for internal ring accuracy rotation. Model RB is the primary type of crossed roller bearings. The outer ring is divided into 2 pieces. The inner ring is an integral structure, which is most suitable for occasions requiring the inner circle’s rotation accuracy.

The outer ring of this type of bearing is divided into 2 parts in the axial direction and the inner ring as a whole; the cylindrical rollers are arranged in 2 90°V-shaped raceways at a 90° included angle of 1:1, and spaces separate the cylindrical rollers. In the future, this kind of bearing will have a compact structure so that a set of bearings can bear radial load, axial load, and overturning hurdle at the same time while ensuring structural rigidity, greatly simplifying the design of the shafting structure; Can be preloaded to facilitate installation and maintenance work further.

At the same time, this type of bearing has the characteristics of High precision, High load, and high rigidity, which is very suitable for robot rotating parts, manipulator joint parts, CNC indexing workbenches, medical equipment, and measuring instruments. It is especially ideal for features requiring the inner ring’s rotation accuracy.
