  1. This screw drive consists of motor, gearbox, lead screw. Control system transmits instructions to mechanical system, transforming the rotary motion of motor into linear motion of the lead screw. Thus, it achieves pushing, pulling or lifting the load.
  2. All the specifications of the screw drive can be customized according to your needs.
  3. Multi-application. The 22MM screw drive can be used in various intelligent linear drive terminals, such as industrial/agricultural automation, patient lifter, automatic wheel chair, sit&stand lifting desk, traffic facilities etc.
