Product Description

Roller Bearing for Steel Structure Bridge

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.
 

Details:
> Materials: quality steel plate in accordance with ASTM A709 grade 36, 50, 50W; cold-rolled or heat treated steel pin. Custom materials are also available. 
> Standards: AASHTO, ASTM or other custom standards. 
> Anti-corrosion coating: high-solid primers, zinc or zinc / aluminum thermal spray coatings and other custom coating. 

Note:
Rocker bearing is stiff without any compressibility under vertical load. In this circumstance, a thick elastomeric bearing pad or other pad with high elasticity is recommended to be placed between the bearing and piers.
