Excellent fatigue durability! A strip-shaped rubber bearing made by integrally vulcanizing elastic rubber and hard rubber.
The "ST Pad" is a strip-type rubber bearing for bridges, reinforced with hard rubber in the middle of elastic rubber to suppress the bulging of rubber due to vertical forces. It possesses the basic functions required at the bearing section of a bridge (load transfer function and displacement following function) and is used in short-span concrete bridges with minimal expansion, such as pre-tensioned slab girders. It can absorb expansion and rotation in all directions, making it suitable for skewed and curved bridges. 【Features】 ■ Used without gaps when laid out perpendicular to the bridge axis ■ Corrosion-resistant due to its laminated structure of elastic rubber and hard rubber ■ Excellent fatigue durability, requiring minimal maintenance ■ Absorbs vibrations during vehicle passage ■ Can be used in conjunction with the ST-type anti-corrosion anchor device (displacement restraint structure) *For more details, please refer to the PDF document or feel free to contact us.
