**Loads and Speeds

Load and speed limitations must be ascertained in order to insure proper bearing design. If design limits are exceeded, the bearing life will decrease and could result in premature failure. To determine the capacity of a bearing, use the following PV formula.

PV = The load per square inch of project area
P = Load
I.D. x Length

V = Shaft velocity in feet per minute
