These bearings can be supplied with corrosion protection and are characterized by high performance, a long operating life, and low friction. Axial/angular contact spherical plain bearings: If high axial forces occur, then axial and angular contact spherical plain bearings are the right solution. Particularly in the maintenance- free version with ELGOGLIDE , they feature a higher than average performance and long operating life. System solution for central joint bearing arrangements Maintenance-free radial spherical plain bearing for stabilizing Central joint system: An advantageous alternative is the railcar bodies and for the suspension of shock absorbers complete central joint in the form of a ready-to-install unit, which considerably simplifies the surrounding structure.
