Disc Bearing
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.
The bearing uses a high-strength polyurethane disc to carry vertical loads and accommodate rotational deformation, while a centrally arranged shear pin resists horizontal forces. The bearing offers high durability, and any damage to the disc can be visually inspected during maintenance.
