More and more injection molding machines utilize ball screws with accurate servo motors to ensure the quality and shorten the manufacturing cycle. The ball screws for the injection molding machine are required to bear high load and rotary movement starting/stopping at high speed within a short distance, which places high demands on bearings and lock nuts as well. Applications such as injection molding machines, robots and machine tool spindles require precision rotary motion with a higher degree of stiffness and positional accuracy.
