These PV bearings use an Oiles bearing as a sliding material.
- The spherical projection absorbs rotation and follows the rotation of the girder in all directions.
- It can handle a large reaction force, so it is also used for large arch and truss bridges.
Note: PV sliding bearings are also available.
- A PV bearing is a fixed bearing that consists of a spherical protrusion on the lower shoe mated with a spherical indentation in the upper shoe.
- The bearing fixes forces in the axial and perpendicular directions while absorbing rotation.
