Ball Screw Assemblies

Introduction to Ball Screw Assemblies

Ball Screw Assemblies are a type of linear motion technology. They are a smooth functioning process, in which rotational movement is translated into linear motion using a ball screw shaft, ball nut and balls.

Benefits of using Ball Screw Assemblies

  • The principle of internal recirculation creates a smooth rotation
  • The large number of balls recirculating allows for a high load rating
  • Move heavy loads at fast speeds with accuracy
