xiros® plastic ball bearings

xiros® plastic ball bearings require no external lubrication, are corrosion resistant (when used with glass or plastic balls) and operate quietly, making them a cost-effective alternative to steel ball bearings.  Comprised of a tribopolymer blend, the all-plastic components are lightweight, chemical resistant and non-magnetic and can safely be used in medical  or food processing environments.  While the xiros® plastic material consists of a blend of base plastics, solid lubricants, fibers and filaments, the balls are typically made of glass, plastic or stainless steel.  All bearings are also rigorously tested in our state-of-the-art test lab.



  • 100% self-lubricating and maintenance-free
  • Highly corrosion-resistant (washable)
  • Non-magnetic (when using glass or polymer balls)
  • Can be used from -148˚F to +302˚F
  • FDA-compliant
  • Lightweight – 60% lighter than metal
  • Shipping within 24-48 hours
  • No minimum order quantity
Use the xiros® service life calculator to quickly determine a ball bearing suitable for your application, and then calculate its expected service life.
