Thrust spherical plain bearings

Thrust spherical plain bearings can accommodate a radial load Fr in addition to an axial load Fa (fig. 1). However, the radial load must not exceed 50% of the simultaneously acting axial load. When the resultant load is constant in magnitude, then use

P = y Fa

where
P=equivalent dynamic bearing load [kN]
Fa=axial component of the load [kN]
y=load factor depending on the ratio of the radial to the axial load Fr/Fa (diagram 1)
