WebFor 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. Webstress can be calculated as the applied force divided by the projected area of contact - Average bearing stress f p = P/(d b t), where P is the force applied to the fastener. - The …
