Aohong is a professional manufacturer of Laminated Rubber Bearings, offering high-quality Rubber Bearings designed for reliable performance in bridges, buildings, and structural applications. These bearings consist of multiple layers of natural or neoprene rubber reinforced with steel plates, bonded through vulcanization, providing excellent vertical stiffness to transfer loads and outstanding horizontal flexibility to absorb displacement and rotation. Rubber Bearings effectively reduce vibration and dynamic load impact, improving structural stability and service life. With strong corrosion resistance, high durability, and minimal maintenance, they are widely used in highway bridges, railway bridges, precast concrete slabs, steel structures, and stadium constructions.
Material Composition
- Rubber Options: Natural rubber (NR) or Chloroprene rubber (CR)
- Steel Reinforcement: High-strength steel plates embedded between rubber layers
- Optional Sliding Surface: PTFE (Teflon) plate for sliding laminated bearings
- Durability: Designed to resist aging, corrosion, and extreme weather conditions
