Many ball bearings are made of metal. But often an application calls for ball bearing that is a little more specialized. One common non-metal ball bearing is the nylon ball. Nylon Ball bearings can be used in the Food & Beverage, Industrial, and Medical Industries. Often used in knobs and toggle switches, for check valves, light load bearings, and other applications where low cost and resiliency are more important than hardness. By providing more toughness than most plastics even used without lubrication, Nylon Balls are often a more suitable choice. Choose from a variety of sizes to fit your needs.
