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

  • Shank strength (S)

male threaded rod end
S1 = [(root diameter of thread2 x .78) - (N2 x .78)] x X
 

female threaded rod end
S1 = [(J2 x .78) - (major diameter of thread2 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
