Precision Rolled Ball Screws

Precision Rolled

Thomson Precision Rolled Ball Screws come in a full range of diameters, leads, and ball nut configurations, in either preloaded or non-preloaded types, all in industry-standard envelopes. They provide dependable accuracy and repeatability at an economical price.  Featuring Tangential Ball Returns, a Thomson design which minimizes recirculated bearing ball deflection, for smoother and quieter operation.   Standard flanges are offered for many of our ball nut models

Precision Rolled Ball Screw Highlights

  • When replacing conventional actuation systems (such as acme screws, hydraulics, or pneumatics), ball screws can use smaller, less-expensive drive motors reducing the need for auxiliary equipment
  • Over 90% efficiency with a constant low coefficient of friction
  • Dependable accuracy and repeatability at an economical price
  • Gothic arch ball groove geometry extends service life, reduces lash, and optimizes stiffness in preloaded assemblies
  • Optional wiper kits and end support blocks increase service life
  • Available in a full range of diameters, leads, and nut configurations, either preloaded or non-preloaded types
  • Non-standard lengths available
