SA-47 Randon Oriented Fibre Bearing Pad Verified by manufacturer 6 months ago
Verified by manufacturer 6 months ago
Bearing pad.
Application
- SA-47 random oriented fibre bearing pads have been widely used in construction applications such as structural bearings, precast/prestressed concrete structures and bridges, masonry pads and railway tie pads.
- SA-47 material is also used for vibration isolation and shock reduction applications.
Description
SA-47 bearing pads are made from masticated rubber using a blend of recycled rubber compounds and synthetic fibre reinforcement. The ROF, or random oriented fibres, provide enhanced compressive strength, stiffness and tensile strength when compared to unreinforced or virgin bearing pad materials.
Features and benefits:
- Distributes load between two structural elements evenly.
- Accommodates non-parallel, load bearing surfaces.
- Allows for small rotations.
- Reduces electrolytic action between dissimilar metal elements.
- Twice the compressive load of plain neoprene/nitrile materials.
- Provides vibration and shock isolation in structural applications.
- Meets most state DOT specification.
- The product does not have a sliding surface, accounts for rotation and uneven surfaces and maybe a very small amount of horizontal movement through material deformation.
