Radial spherical plain bearings manufacturer

Radial spherical plain bearings can accommodate a certain amount of axial load F_a in addition to the simultaneously acting radial load F_r fig û ). When the resultant load is constant in magnitude, the equivalent dynamic bearing load can be obtained from

P = y Fr

where

P = equivalent dynamic bearing load, kN

F_r = radial component of the load, kN y = a factor that depends on the ratio of the axial to the radial load F_a/F_r

- for bearings requiring maintenance Diagram p )

- for maintenance-free bearings

P = y Fr

Spherical plain thrust bearings

Spherical plain thrust bearings can carry a radial load Fr in addition to the axial load F_a. However, the radial load must not exceed 50 % of the simultaneously acting axial load fig |jo). When the resultant load is constant in magnitude, then
