What Are Self-Lubricating Bushes ?

Self-lubricating bushes (also called bearings or sleeves) are mechanical components designed to reduce friction between moving parts without the need for external lubrication.

Materials Used

Sintered bronze or iron impregnated with lubricating oil
PTFE (Teflon) composites
