xiros® plastic ball bearings are an excellent cost-effective alternative to steel ball bearings. These ball bearings are comprised of a tribopolymer blend, making them maintenance-free due to not needing external lubrication. They are lightweight, non-magnetic, and chemical-resistant, making them ideal for the medical or food processing industries. Our ball bearings can be used from -148˚F to +302˚F, and many are FDA-compliant. They also have no minimum order quantity and typically ships within 24-48 hours!
