Bearing improper selection generally match the bevel ball screw bearing ball screw must purchase, especially in high-pressure bearing angle design for better choice; when the ball screw axial load, generally deep groove ball bearing will produce a certain amount of axial backlash, deep groove ball bearings and therefore does not apply here. 4. bearing improper installation (1) If the bearing is mounted on the ball screw and the two do not really fit in the case of axial load will result in the generation of backlash, this situation may be due to the shoulder screw is too long or short caused. Verticality (2) bearing lock nut bearing surface and the axis of the V-shaped teeth poor, or parallel to the surface of the locking nut poor will lead to tilt bearing two corresponding direction; therefore shoulder screw locking screw V-shaped teeth and bearing cap bearing surface to be processed simultaneously, in order to ensure vertical, if the grinding process better way. (3) with two lock nuts with spring washers to secure the bearing to prevent loosening operation. Self-locking ball screw, Korea and Taiwan transmission machinery (certified), ball screw is provided by Dongguan Transmission Machinery Co., Korea and Taiwan.
