Abstract

The self-lubricating effect of polymer composite cage fabricated by pure PTFE (Teflon), composites PTFE + MoS2 + glass fibers, PTFE + bronze particles were verified by friction coefficient and wear rate. Cage center-of-mass orbits for cryogenic ball bearing with different solid lubricant are demonstrated. In the case of MoS2 containing composite cage, circular orbit is observed. Among the tested materials, the composites PTFE with additive MoS2 have shown good friction coefficient.
