xiros® plastic ball bearings can reduce costs by 40% compared to metal balls

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. Use the xiros® service life calculator to quickly determine a ball bearing suitable for your application, and then calculate its expected service life. Have a unique design or need for a custom component?  Click here to request a free custom design with the ability to upload a CAD file and describe your unique application requirements.
