Bearing Life

The following PV curves are to be used only as a guide for bearing selection - they are based on laboratory condition testing at ambient temperature (20° C). Real user applications may have specifi c environmental conditions that will affect bearing performance. BNL’s design engineers can further advise on bearing design and selection for specifi c conditions - elevated temperatures, lubrication, fl uctuating loads or speeds, etc.
