static Radial Load Calculation
The maximum static radial load permissible for a rod
end depends on three factors: race material compressive strength; rod
end head strength; and shank strength. The maximum static radial load
is determined by taking the lowest of the three following
values:

Race material compressive strengths (R)

Rod end head strength (T)
insert construction
cartridge type construction
male threaded rod end
S_{1} = [(root diameter of thread^{2} x .78)  (N^{2} x .78)] x X
female threaded rod end
S_{1} = [(J^{2} x .78)  (major diameter of thread^{2} x
.78)] x X
Where:
E = Ball Diameter
H = Housing Width
X = Allowable Stress (see table below)
D = Head Diameter
N = Diameter of Drilled Hole in Shank of Male Rod Ends
J = Shank Diameter of Female Rod End
