Product Description

Product Description

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.

Application

Pot bearing is mainly used in such fields

• Bridge which the structure with rotations in various directions.
• Large curved or skewed bridge.
• Highway.
• Other fields which also need to meet the need of large load and rotation.
• 

Feature

• Providing longer service life compared to elastomeric bearing pad.
• Large horizontal displacement and large bearing capacity.
• Accommodate rotations at any axis and the appropriate movements of the bridge.
• Totally detachable, and easy to dismantle if any element has to be replaced.
• Saving steel and reduce costs.
