All values are based on 72oroom 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.

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 (plane) 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 (plane) 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.
