Thrust spherical plain bearings have a convex spherical surface on the shaft washer and a corresponding concave spherical surface in the housing washer. They are intended primarily for axial loads, but can also accommodate combined radial and axial loads. The radial load component of a combined load should not exceed 50% of the axial load component. When radial loads are higher, it is advisable to combine the thrust bearings with radial bearings in the GE dimension series. Thrust spherical plain bearings are separable, meaning the shaft and housing washers can be mounted separately.
