JOJI PTFE composite straight (cylindrical) bushings are suitable for oscillating, rotating and axial reciprocating motions and can withstand radial loads. Despite the thin-walled design, they can withstand heavy loads. Also provides good heat dissipation, so relatively high sliding speeds can be achieved.
