Self-Lubricating Rod-End Bearings

Threaded-stem or tapped-type self-lubricating rod-end bearings, used in controlling and linking mechanisms in machines

, are suitable for high-load, low-speed applications with hanging angles or that require linear, rotational, or oscillatory motion. The rodend body is constructed of zinc-plated steel; the ball socket is made of bearing steel 100 Cr6, hardened and ground; and the external ring is a special bronze material that makes the rod ends self-lubricating and maintenance-free. The bearings operate in temperature from 30 to 150°C.
