Tribology is the science & technology of interacting surfaces in relative motion. This involves analysis of friction, wear and lubrication, which exists in all machinery as these have parts that are subject to friction and wear.

As an attempt towards reducing friction and wear to the minimum, role of manufacturing of bimetal & trimetal plain bearings, together with proper surface treatment and precision machining is a challenge.

Today, PBW enjoys a remarkable position in the organized sector of engine bearing manufacturing, specializing in thick wall bearings.
