Plain bearings do not have a dynamic load rating, but are rated by their limiting PV, which is a combination of load over a given surface area and the velocity.
P – pressure or load in pounds per square inc (psi) or kilograms per square centimeter (kg/cm2).
V – velocity or surface speed in feet per minute (fpm or sfm) or meters per minute (m/min).
PV – pressure velocity value, P x V
NOTE: All three parameters must be met by an application for the bearing to perform properly. Max P times Max V does NOT equal Max PV: if one increases, the other must decrease in order to not exceed Max PV.
