Rubber Bearing (Elastomeric Bearing)
Steel-reinforced rubber bearings are widely used in bridge and road structures to transfer loads between the superstructure and substructure,
allowing safe rotation, horizontal movement, and thermal expansion/contraction. The product meets international standards, offers high durability, easy maintenance, and a long service life.
Technical Specifications
- Type: Steel-reinforced rubber bearing; laminated elastomeric bearing with steel plates.
- Standards: AASHTO – BS EN 1337 – TCVN.
- Materials: Natural rubber (NR) or neoprene (CR) + high-quality reinforcing steel plates.
- Rubber hardness: 55 ± 5 Shore A.
- Load capacity: 50 – 2500 kN (depending on product code/model).
- Excellent rotation and shear performance with stable elastic deformation.
- Ozone and UV resistant, weather durable, 50-year service life.
KAWAKIN BRAND (JAPAN)
Kawakin is one of the leading suppliers of bridge bearing solutions, delivering absolute reliability for infrastructure projects.
Choosing Kawakin rubber bearings is an optimal solution, ensuring stability and minimizing maintenance costs for road bridge structures.
Kcoat Coating Technology (Chlorosulfonated polyethylene)
Kawakin rubber bearings are manufactured with proprietary Kcoat coating technology, enhancing exceptional service life and resistance to harsh environments:
Function
Kcoat is a chlorosulfonated polyethylene-based coating layer that encapsulates the rubber externally.
Benefits
-
Enhanced durability & service life: Protects the rubber bearing against oxidation, ozone, and environmental factors (UV radiation, chemicals) over long-term exposure.
-
Improved degradation resistance: Helps prevent rubber deterioration and significantly extends the working life of bridge bearings compared to conventional products.
