 Pot rubber bearing
Introduction of the basin-typed rubber bearing:
The basin type rubber bearing can serve as a kind of new product with large support reaction, large horizontal displacement and large turning angle and other different kinds are available at the users’ requests.

The pot bearings gpz (ii) is designed as per standard jt391-1999 pot-type elastomeric pad bearing for high way bridge, which is a replacement of the previous pot bearing of jt3141-90. For a distinction, the new products is renamed gpz (ii).
The pot bearing, gpz (ii), is a new type of bridge bearing, made up of component and rubber. It features high loading capacity, great horizontal displacement, smooth rotation, etc.
Fengze Pot bearings are designed to carry combinations of vertical loads, horizontal loads, longitudinal and transversal movements, and rotations.This type of bearing can carry very high loads of over 50,000 kN.
Compared with other types of pot bearing and cast steel roller bearing, it is lighter, structurally more compact and simple, lower in construction height and easier for manufacture. As less steel is used, it is much cheaper. This bearing is desirable for large span bridges. The capacity of this series bearing is now up to 31 grades, from 0.8mn to 60mn, and can meet the demand from domestic construction of large bridges.
A completely encased natural rubber pad is positioned in a steel pot. Under high pressure the pad behaves like a liquid. The elasticity of the rubber allows tilting movement (rotation) of the piston in the horizontal axis.
Depending on whether the bearing is fixed, guided sliding or a free sliding, Fengze pot bearings accommodate vertical loads and corresponding horizontal forces, as well as movements in longitudinal or transversal directions.
At the same time, one series of railway bridge pot bearings are designed and manufactured in accordance with the requirements of international standards(European EN1337).
In order to define the correct bearing, our engineers take into account the designed load effects, rotations, displacements and type of fixings. Every single component is mechanically worked and assembled by fully qualified and trained workers at the Fengze factory under strict ISO 9001:2000 accredited quality control standards. |
