RADIAL LOAD<br />
MILITARY SPECIFICATIONS<br />
Spherical Bearing Technical Data<br />
The maximum static radial load is calculated using the following<br />
formula:<br />
R = E x H x X<br />
STATIC AXIAL LOAD<br />
The maximum static axial load is calculated using the following<br />
formulae:<br />
• Axial Strength (A)<br />
Where:<br />
1. For four piece insert construction bearings<br />
A = .78 [(E + .176H) 2 – E 2 ] x X<br />
2. For two piece (cartridge type) bearings<br />
A = .65(H 2 ) x X<br />
E = Ball Diameter<br />
H = Housing Width<br />
X = Allowable Stress (see table below)<br />
