Product Description

Product Description

Pot Bearing with Large Load Capacity and Large Horizontal Displacement
Pot bearing is a kind of new type bearing which is composed of pot, elastomeric pad, stainless steel plate, sealing ring and other components. It is designed for bearing the combinations of vertical loads, horizontal loads, longitudinal and transverse displacements and rotations. Pot bearing is ideal bearing for large bridge with the features of large horizontal displacement, light weight, simple structure and easy operation.

Working Principle

There is an elastomeric pad in the pot of the pot bearing, it has fluid properties when it in the state of three-phase stressed, making use of this feature can achieve large rotation of the bearing. In addition, when a relative motion occurs between the PTFE plate which placed on the piston and the stainless steel plate, horizontal displacement can be achieved. Pot bearing can meet the requirements of large end reaction, large horizontal displacement and large rotation, it is suitable for the bridge with large span and large end reaction.

Categories

In addition, according to the displacement ability, pot bearing can be divided into three types: fixed pot bearing (GD), guided sliding pot bearing (DX) and free sliding pot bearing (SX). Fixed pot bearing and guided sliding pot bearing can also be divided into common pot bearing and damping pot bearing. The appearance of these pot bearings is similar, but the difference of internal structure directly determines whether the bridge can be displaced.
