The thrust bearings manufactured by SLB include both ball bearings and cylindrical roller bearings with a single-direction or a double-direction design. Based on customer specification the SLB thrust bearings can be supplied with a massive brass or steel cage. The thrust bearings by SLB can be optionally delivered with a housing washer provided with a spherical surface and a retaining ring provided with a matching spherical surface. The bearings can then eliminate the non-perpendicularity of the seating surfaces.
