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

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

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

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

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

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

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

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

Vertical bearing capacity range: 3000KN-70000KN.

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

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

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