PV Factor

IntroductionSelection Guide Engineering DataBrochure

For plain, dry-running bearings, it is often helpful to reference a pressure-velocity (PV) factor as a guide in determining bearing capability. It should be understood that this factor is actually a variable which reflects the point where surface temperatures are at a maximum, but are still stable. The maximum PV established for FIBERGLIDE is:

PV continuous-60,000
PV intermittent-150,000
