PV (Pressure Velocity)

PV is the unit of measure determined by two factors; Pressure (PSI) and Velocity (SFM)

Formula: P = W/(dxb)

W = Static load on a single bearing

d = Bearing Inside diameter

b = Bearing length

Example: 225lb load applied to a 1-inch diameter bearing x 2-1/4 inches long.

Note: Determining PSI: ID x Length

P= 225/(1" x 2.25") or P= 100 PSI and the velocity is 50 feet per minute

PV= 100(PSI)x 50 feet per minute

Answer: PV= 5000
