Do you need to make modifications to your bearings?
Running Clearance (Click photo to enlarge)
Greater than normal clearance must be allowed: (1) if exceptionally high speed is involved or (2) if higher than normal loading is encountered.
Press Fits (Click photo to enlarge)
Less than normal press fit proves satisfactory: (1) if the bearing is long and the wall is not exceptionally thin and (2) if the bearing is also carrying a moderate load exerted in one direction.
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 area of the bearing. V is velocity in feet per minute of the wear surface (surface feet per minute).
For sleeve 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 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 in.), or 90 lbs. ÷ .75 = 120 psi.
PV = 120 psi x 67 sfpm = 8040 PV
