????If an adequate operating life is to be achieved, a basic requirement is that　the bearing contact pressure is compatible with the operating conditions. The bearing contact pressure identifies the surface pressure occurring in the bearing and is a decisive criterion for the assessment of a spherical plain bearing in each individual application.

p=contact pressure N/mm2

k=contact pressure parameter N/mm2

Cd=Dynamic load rating kN

P=Equivalent dynamic bearing load kN
