Rocker bearing features its pin to permit stable rotations and movements in response to different loads and forces from its superstructure including living load, constant load and earthquake-generated forces, etc.

Features:

Capable to withstand high tensile, compression and shear forces.

Excellent seismic isolation property makes it perfect to resist seismic intensity up to 9 degrees.

Strong structure coming with high durability.

With high impact load-carrying capabilities.

Types:

There are two main types including expansion rocker bearing and fixed rocker bearing as shown in the following pictures.
