What is spherical bearings in bridge

Spherical bearings help absorb shock and support loads in bridges and buildings. They are one of the four main mechanical structural bearings. Their unique spherical contact surface design makes them ideal shock absorbers. Ball bearings come from rubber bearings. They are popular in cold places because they don’t harden or age like rubber does.

The structure of spherical bearings.

This new bridge bearing uses spherical features that enhance its functionality. The main part is a spherical PTFE sliding plate. It creates friction with the core spherical crown lining plate. This setup helps with smooth steering. Silicone grease fills oil storage pits made with special molds. It coats the PTFE plates to lower friction and cut down on sliding losses. The sliding plates for both upper and lower supports are like bowl-type supports. They handle movement in different directions well.

Advantages of spherical bearings

Spherical bearings provide flexible rotation, high load capacity, and a broad turning angle. Spherical bearings transfer force through their round surface. The reaction force on the base concrete is even, which leads to effective unloading. The support rotates by sliding along a spherical surface. This design allows for large rotation angles. Rubber aging is not affected by any factors. This makes it great for low-temperature areas.
