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

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

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

When the vertical bearing capacity is more than 50000KN, it can be designed separately.

Vertical bearing capacity range: 3000KN-70000KN.

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

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

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

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

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

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