Crossed cylindrical roller bearings for robots have compact structures. The rollers are arranged in 90��crossing between inner and outer rings. They are able to carry radial, axial and moment loads at the same time .
As rollers and raceways are line contact, the elastic deformation is little when the bearings carry heavy loads. This type of bearings carry heavy loads. This type of bearings are widely used in applications required high stiffness, compact structures and high precision, such as industrial robots, construction machinery and armarium.
