The ball screw assembly of precision mechanical parts, so when used with the following considerations:
  (1) because the friction of the ball screw is very small, if there will be no preload (micro-pre-pressure, too) screw placed vertically, the nut due t o weight and detached from the screw shaft down, vertical use, please do careful. If the nut off the screw, the ball will fall off. In addition, the loop catheter and ball circulation department is also the risk of damage. If the nut from the screw off, please contact the after-sales and technical staff.
  (2) Please note that due to the cycle part of the ball screw nut (loop catheter, end caps, etc.) to highlight the outside of the nut, not percussion and collision.ball bearing screw
  (3) Do radial load, torque load directly added to the ball screw. If the role of the radial load, torque load, will make the life of the screw is extremely reduced or lead screw operation is not smooth.
  (4) the screw combination with other mechanical parts to install, please do not remove the nut from the screw. In case to be separated than the low diameter of 1mm screw groove casing with the auxiliary system, remove the nut and the ball with the same time careful not to let the ball fall off.
(5) The ball screw thread groove is processed after quenching and grinding, the external parts forced into the edge of the screw shaft or nut rolling groove indentation, installation parts, be careful not impose excessive external force on the screw or nut.single ball bearing
(6) If the ball screw support at both ends of the center of the central axis and the nut when the different heart will be on the ball screw excessive frictional resistance, resulting in increased torque, fever and other phenomena. Ball screw to early wear and tear, greatly shorten its life. Therefore, the installation must be correct screw "3.1". In addition, after you install, please be sure to turn the screw and nut to move the effective stroke of the screw , to confirm whether there is interference and other anomalies.
(7) installation of bumpers, the best in the screw at both ends to avoid running over travel limit damage to ball screw.crossed roller bearing
