Circles are divided into 24 categories:
D350， D400， D450，D500，D550，D600，D650，D700，D750，D800，D850，D900，D950，D1000，D1050，D1100，D1150，D1200，D1250，D1300，D1350，D1400，D1450，D1500；
According to the actual situation of the project, this series of bearings can also be specially designed according to the technical requirements.
2 Design angle θ (rad)
The design angle of this series of bearings is 0.006rad
When the design angle exceeds 0.006rad or the customer has special needs, special design can be carried out according to the actual situation.
3 Design displacement of bearing
The normal design shear strain of the bearing is 1.0, and 2.0 in case of earthquake; When customers have special needs, special design can be carried out according to the actual situation.
2、 Product advantages:
It has strong resetting ability, alleviates aging, is convenient for installation and construction, does not affect the bridge body and pier when replacing, and has low maintenance and management costs.
3、 Scope of application:
It is applicable to all kinds of roads and municipal bridges in areas with seismic intensity of 8 degrees and below.
