Ball Screw Assemblies

Precision ball screw drives for converting rotary motion to controlled linear movement in machine tools, automation and process equipment.

Engineering overview

A ball screw assembly pairs a precision screw with a ball nut so rotary input produces accurate linear travel. The rolling elements reduce friction compared with acme screws, supporting higher efficiency, repeatability and duty cycles in CNC axes, presses, medical equipment and aerospace mechanisms.

System design must consider axial load, speed, stiffness, backlash control, lubrication and support bearing arrangement at both screw ends.

Typical applications

  • CNC machining centres and lathe axes
  • Industrial robotics and pick-and-place systems
  • Medical imaging and laboratory automation
  • Aerospace actuation and test rigs
  • Packaging, printing and semiconductor handling

Design considerations

Precision class

Lead accuracy, preload and manufacturing grade affect positioning repeatability in machine tools and measuring equipment.

Load and duty

Dynamic and static load ratings, acceleration profiles and shock must be evaluated for the full drive train, not the screw alone.

End support

Fixed and floating support bearings carry axial and moment loads. See ball screw support bearing guidance for angular-contact arrangements.

Lubrication

Grease or oil selection depends on speed, environment and maintenance interval. Match lubricant to bearing and nut suppliers where specified.
