  • Free Float Type – Provides both rotational capacity as well as multi directional sliding.

  • Guided / Sliding Type – Provides rotational capacity, free sliding in one direction only, and is laterally restrained.






Installation details of Fixed Spherical Bearings:
1. Fixed Spherical Bearings shall not be used on bridges where the concrete for the beam, pier and platform is
lower than C35, unless specially approved by the designer.
2. Install Fixed Spherical Bearings: To adjust bearing level putting wedges under bearing base plate, and to
make sure (real factory) QZ Spherical Bearing for Bridge base plate above the pier and platform top
20 ~ 50mm.Center the QZ Spherical bridge bearing to the right place. Filling in bolt holes and bearing bottom cushion withepoxy mortar.
3. The Fixed Spherical Bearings shall connect with the beam, pier and platform with the embedded bolts. If
necessary, welding to the embedded steel plate is allowed, but cautions shall be taken to bearing and
concrete being damaged by the high heat from the steel bearing being welded.
