Extending Bearing Life in Off-Highway Equipment

A thin dense chromium coating has been developed that extends bearing life, particularly in problem environments. The coating possesses exceptional adhesion to the base metal, which allows it to withstand the extremely high unit loads present in bearing raceways.

In conventional bearings life typically ends due to wear or an ultimate material failure in the raceway or rolling element. The actual cause of the failure can stem from many factors. Corrosion, contamination, loss of or poor lubrication, and mechanical damage, all accelerate failure. The coating reduces the detrimental impact of these factors, thus extending bearing life.
