9. Permissible load. For shaft velocities above 200 feet per minute, the permissible load is found from the following:
P = 50,000 v
Where: P = Safe load, psi of projected area ( X bearing ID X length). v = Shaft velocity in ft./min.
10. Static capacity: Specific static capacity is 75 percent of the maximum pure radial load, which will produce a permanent set of less than 0.1 percent in the bearing at any contact area between shaft and bearing at zero velocity. (Note: The specific static capacity given is intended as a guide in selecting the proper bearing and no tests are required to determine this factor for acceptance of bearing).
11. Static load: The maximum load should not exceed 8,500 psi of projected bearing area (length X inside diameter of bearing).
12. Radial crushing strength. The radial crushing strength of cylindrical parts shall be not less than the value determined from the following:
S = Lt2 X 22,500
D-t
Where: S = Radial crushing strength in pounds
D = OD of bearing in inches
t = Wall thickness in inches
L = Length of bearing in inches
