The so-called sleeve bearing refers to the self-lubricating bearing the external circle of which has no flange edge and with no axial positioning function.

Yulong plastic self-lubricating bearing is the ideal product under oil-free lubrication status. It enjoys the high temperature and wearing resistance performance better than general engineering plastics. Some models of bearings could work at 500℃ at maximum. They are applicable to different kinds of motion modes.
