Crossed roller surface profile measurement are roller between the inner and outer wheel intervals intersecting at right angles to each other arranged. They can withstand the load from all directions (such as an axial thrust or momentum load, etc.). Due to the roller surface into line contact with the rail, therefore, the possibility of bearing a load and elastic deformation is small. This type of bearings are widely used in industrial automation, such as robots, machine tools and medical facilities, etc., need high rigidity, compact and high-speed still ensuring accurate of occasions.
In cross roller bearings, cylindrical roller in was due to a 90 ° V-shaped groove raceway is vertically aligned with each other through a spacer retainer, so a cross roller bearings can bear radial load, axial load and load torque loads in all directions and so on. Minimum size of the inner and outer rings are miniaturized, in particular close to the limit of a very thin type of compact size, and has high rigidity, it is most suitable for the joint portion or a rotating portion of the industrial robot, the rotary table of the machining center, use the rotating portion of the manipulator, precision rotary tables, medical equipment, meters, IC manufacturing equipment, etc..
