Application

SA-47® ROF Bearing pads have been widely used in construction applications since 1947. Typical applications include:

  • Structural Bearings
  • Precast/prestressed Concrete Structures
  • Bridges
  • Masonry Pads
  • Railway Tie Pads
  • Lamp Post Pads
  • Railcars

Description

The random orientated fibres (ROF) within the SA-47® bearing pad provide enhanced compressive strength, stiffness, and tensile strength when compared to unreinforced or virgin bearing pad materials.


These pads provide compensation for surface irregularities and non-parallel load bearing surfaces. They can also be provided with a Teflon® surface for use in expansion bearings and pipe slides.


SA-47® is impervious to most oils and resistant to the effects of steam, water, mildew, and brine. Other features and benefits of SA-47® bearing pads are as follows:

  • Distributes load between to structural elements evenly
  • 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 specifications
  • The product does not have a sliding surface, accounts for rotation and uneven surfaces, and potentially even a small amount of horizontal movement through material deformation
