As a precision transmission element, ball screw should not only adopt lead screw, nut and ball, but also select bearing with high axial stiffness, low friction torque and high running accuracy. Ball screw support commonly used two-way thrust angular contact ball bearings, tapered roller bearings, needle and thrust roller combination bearings, deep groove ball bearings and thrust ball bearings. Choose ball screw high lubrication machine tool, quality assurance. At present, ball screw support adopts single row thrust angular contact ball bearing with 60 ° contact angle. Compared with general angular contact ball bearing, the axial stiffness is increased by more than two times. Moreover, the thickness of inner and outer rings has been selected when the product is delivered from the factory. When assembling and debugging, the inner and outer rings can be adjusted as long as the inner and outer rings are pressed with nuts and end caps The whole preload is convenient to use. When purchasing, the end of the ball screw pair should be ordered from the manufacturer according to the design requirements, and the shoulder or thread can be processed.
