051015202530 PV LIMITS: Any material which carries a sliding load is limited byheat buildup.The factors that affect heat generation rate in an
application are the pressure on the nut in pounds per square inch
and the surface velocity in feet per minute.The product of thesefactors provides a measure of the severity of an application.P=ThrustxV=Speed< !
* Maximum thrust is the maximum continuousdynamic thrust subject to Thrust x Velocity limitation.
