Screw with thrust angular contact ball bearings

Ball thrust angular contact ball wheel bearing with a contact angle of 60o, with a high axial stiffness, mainly withstand axial load, but also bear certain radial load.
In withstand axial load, the load should be based on the size and characteristics of paired configuration, the configuration to be applied to a certain load. Machine screw angular contact thrust ball bearings for precision spindle bearings basically the same requirements and the general use of 2,4-tolerance level. Because the system requires a flexible and precise movement of the axial displacement, thus requiring the bearing should have a low and uniform friction torque, in particular that has a low starting frictional torque,
