Product description:

(Integrated Inner/Outer Ring Type)

YOGIE Crossed roller bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads.

RU special type is a bearing with integrated inner- and outer ring. It is being used in

cases where high rotational accuracy of both the inner- and outer rings is required.
