PV Data Chart
PV Calculation
PV is a means of measuring the performance capabilities of bearings.
P is expressed as pressure or pounds per square inch on the projected area of the bearing. V is velocity in feet per minute of the wear surface (surface feet per minute).
For sleeve (plain) bearings, the surface speed is .262 (pi ÷12) x RPM x shaft diameter in inches. P is equal to the load on the bearing in pounds divided by the projected area in square inches. For sleeve (plain)bearings, the projected area is the length x the inside diameter of the bearing.
PV is then obtained by multiplying P x V as shown in the following example:
3/4" shaft @ 341 RPM, 90 lb. total load, bearing length 1".
V = .262 x RPM x shaft diameter, or .262 x 341 x .750 = 67 sfpm.
P = total load ÷ projected area (area = .750 x 1.0 = .75 sq. in.), or 90 lbs. ÷ .75 = 120 psi.
PV = 120 psi x 67 sfpm = 8040 PV.

All values are based on 72° room temperature and the standard lubricant for the bearing in question. All of the V’s (and therefore the PV’s) can be raised by special lubricating techniques.
