Description

Structural Bridge Pot Bearings for Bridge

We manufacture many types of pot bearings - including fixed pot bearings, sliding guided pot bearings and free sliding pot bearing

The basic elements of a Pot Bearing consists of a shallow cylinder, known as pot, an elastomeric pad known as disc,a single or set of sealing rings, piston and sliding surfaces. Masonry plates and base plates are common for the installation of pot bearings, as they allow attachment of the bearings and increase the support area on the pier and abutment. Pot bearings are fixed against all translation unless they are used with a PTFE sliding surface.

Advantages of Pot bearings:
Pot bearings are usually recommended when bearing rotations are large, compact designs and long term servesability are required.

Pot bearings provides longer service life compared to elastomeric bearings.
Smaller in size compared to elastomeric bearings.
Longer maintenance time.

Pot bearings can sustain many cycles of very small and large rotations.
Economical repair as replacement of elastomer disc only.
Does not get effected by external atmospheric correction.

Additional fixtures for Pot Bearings:
We also offer additional fixtures for installation of pot bearings like temporary bearings, PTFE sliding bearings, studs, base plates, masonry plates with welded studs etc and will be happy to receive your complete requirements.
