Single direction cylindrical roller thrust bearings are composed of a housing washer (GS), a shaft washer (WS) and a cage-roller assembly. They are characterized by a very low axial section, and high load carrying capacity and stiffness. They can support only axial loads in one direction, and cannot withstand radial forces and tilting moments.
