Spherical Bearings

KF Bearing – Fixed spherical bearing Kf – These bearings can transfer horizontal loads from all directions.

This is achieved by a stop ring that locks the bearing. The stop ring is part of the calotte receiver. A sliding surface between the calotte plane and the top bearing parts is used, to keep horizontal forces away from the calotte.

KGe Bearings – Unidirectionally sliding spherical bearing KGe – Bearings of this kind are movable in one direction and perpendicular fixed by guide gibs that transfer the horizontal loads in that direction. An inclination of the guiding gibs perpendicular to the movable direction caused by rotation is compensated by rollable designed tilting strips. Suitable sliding members are used between the guide gibs and tilting strips.

KGa Bearing – bidirectionally sliding spherical bearing KGa, This kind of bearing can transfer displacements in the longitudinal as well as in the transversal bridge direction. It is not able to transfer horizontal loads, though.
