Precision Rolled 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
