Crossed roller bearing is also called crosswise roller bearing.With each roller perpendicular to adjacent roller in a 90°Vgroove，cylindrical rollers or tapered rollers are arranged crosswise.

The crossed roller bearing can bear radial,axial load from all direction.Since the dimension of the inner and outer ring are minimumized，especially the thin type，this type of bearing can save space and weight very much.

RU series crossed roller bearings have an integrated inner and outer rings.Becuase there are mounting holes in the outer ring,the bearing does not need press flange or housing.The performance of the bearing is minimally affected by the mounting procedure,so it can ensure stable rotation and accuracy.This type can be used to the applications where outer ring and inner ring rotate.
