Description

The spherical bearing transfers force reliably and rotates smoothly. It not only has great bearing capacity, large displacement, etc. as the pan rubber bearing, but it is more suitable for bearings of large turning angles.

Compared with the pan bearing, it has the following advantages:

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

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