Roller bearings are applied in railway

The bearing is fixed in displacement by the design of a limiting ring located at the upper plate. This design allows to transmit the horizontal load acting on the bearing from the upper plate to the bottom plate. In order to prevent horizontal load from acting on the top of the guide spherical bearing, there is a sliding surface between the upper plate and the convex calotte.

Displacement in both lateral and longitudinal directions are allowed but not subject to horizontal load.

Elastomeric bearings are procedused follwing stardards : AASHTO, ASTM, BS, EN…
