At present, the rigid seismic method and flexible seismic method are adopted in the world.

Vertical bearing capacity range: 3000KN-70000KN.

When the vertical bearing capacity is more than 45000KN, it can be designed separately.

Qpz bridge pot bearing is a new type of innovative bearing with unique advantages. Its movable bearing adopts a middle oriented structure, which can ensure that the beam end rotates in the plane through the rotation of the middle steel lining plate

The vertical design bearing capacity of the bearing is 400-60000KN

This series of bearings adopt elastic damping elements, which have the characteristics of clear mechanism, stable structural parameters and excellent damping performance.

There are five levels of beam capacity: 1000KN, 1500KN, 2000KN, 2500KN, 3000KN.

There are 24 levels of vertical bearing capacity: The capacity range from 2500KN to 50000KN.

There are 6 levels of bearing capacity of simply supported T-beam: 1000KN, 1500KN, 2000KN, 2500KN, 3000KN, 3500KN.

There are four levels of vertical bearing capacity 1500KN, 2000KN, 2500KN, 3000KN.

The friction coefficient of bearing design, under the condition of PTFE plate with silicone grease lubrication, when the stress is about 30MPa, the values are as follows: normal temperature 0.03, low temperature 0.05

There are nine levels of vertical bearing capacity: 2500KN，3000KN, 3500KN, 4000KN, 4500KN, 5000KN, 5500KN, 6000KN, 7000KN.
