Tribology, a word coined in the 1960s from the Greek “tribos” for “rubbing,” is the science of interacting surfaces in moving contact involving multi-disciplines of friction, lubrication, and wear. Tribological issues are frequently the underlying cause of a majority of mechanical equipment failures and degradation. Kalsi Engineering personnel have been supporting the industry by providing fundamentally sound tribological solutions to dynamic seal, bearing, and mechanical contact problems by analysis, testing, research, and development.

Laboratory tests confirmed analytical predictions of lower friction coefficients obtained with a novel bearing designed for high load/high speed applications.
