The intersecting roller bearings are arranged at right angles between the inner and outer wheels. They can support loads from all directions at the same time (such as axial, thrust, or momentum loads). As the roller contacts with the track surface in a linear manner, the bearing under load has little possibility of elastic deformation. This type of bearing is widely used in industrial robots, working machines and medical facilities where high rigidity, tightness and high speed are required to ensure accuracy.
