IB-21 bearing uses high strength glass fiber with epoxy resin as its supporting layer, and special lubricating fiber or FTFE wound fiber as its lubricating layer, performing an outstanding anti-wear feature and low friction coefficient under high load and low speed condition. And it can even play a good self-lubricating properties and high bearing pressure in a long time without oiling.
