QZ Spherical Bearing for Bridge

QZ Spherical Bearing for Bridge
Product Detailed
1.spherical bearing for bridge. 2.QZ spherical bearing. 3.The spherical bearing QZ has the following advantages:

 1. spherical bearing for bridge (QZ spherical bearing)

 

2.The spherical bearing QZ has the following advantages:

1)The bearing transfers force through the spherical surface,so no contraction of force will occur,and the reaching force on concrete is relatively even.

2)The bearing rotates through the sliding of the spherical PTFE plate,with less turning moment,which is only related to the radius of the spherical surface and friction coefficient of the PTFE plate,not subject to the turning angle of the bearing,so it is especially suitable for large turning angles.The design tuning angle may be 0.05rad or more.

3)The turning of the bearing is consistent in all directions so it is suitable for wide and curve bridges.

4)No rubber is used in the bearing so there is no problem of rubber aging affecting the bearing rotation,and it is especially suitable for cold areas.
