Plain Bearings & Rod Ends

Plain bearings and rod ends are sliding-contact supports for oscillation, tilting and low-speed movement. Spherical plain bearings accommodate angular displacement, rod ends add a threaded linkage body, and bushes, thrust washers or strips provide simple replaceable bearing surfaces between mating components.

Questions about plain bearings & rod ends

What should I send to identify plain bearings & rod ends?

Send bore or thread dimensions, bearing form, sliding material pair, tilt angle, load and lubrication. For rod ends, state male or female thread, pitch, hand and housing width; for bushes, include installed bore requirements. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select plain bearings & rod ends?

Choose greasable or maintenance-free contact surfaces from load, oscillation, contamination, available lubrication and required angular movement. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
