Radial spherical plain bearing - made of chromium steel - hardened and phosphated. In addition the sliding surfaces are refined with MoS2. The spherical plain bearings have an anti-corrosion protection, they are low wear as well as self-aligning.
Furthermore, the spherical plain bearings have a circumferential lubrication groove and lubrication holes, consequently the spherical plain bearings can be relubricated on both rings. The spherical plain bearings are suitable for high radial and low axial loads.
