Elastic Rubber Pad

Elastic padding is mounted between the rail foot and the steel sole plate. We offer elastic material made of EVA and steel-reinforced rubber in various thicknesses.

Functions

Main functions of elastic underlay material:

  • Better distribution of the load, over a larger surface.
  • Preservation of the rail construction.
  • Cancels point loads and the resulting fatigue.
  • Absorption of contact irregularities between the rail and the supporting structure.
  • Reduction of noise and vibrations.
  • It minimises wear of the rail and sole plate.

EVA

  • Length: 12 metres on a roll.
  • Width: Any width.
  • Standard thickness: 6 mm. Other thicknesses are possible.
  • When installing separate sheets, it is possible to place lugs on both sides. This is possible in every desired dimension.

    • Steel Reinforced Rubber

    • MK6: 7mm steel reinforced rubber.

    Thanks to better pressure distribution, the use of an elastic underlay mat offers an economic advantage for the life of the rail construction. In addition, a reduction in the load on the supporting structure of at least 25% can be expected (DIN 4132 and CTICM recommendations).

    Because of the excellent quality and good experiences Bemo Rail uses the following types:

    • 14003: For standard applications.
    • 07002: For heavy rail constructions (for higher tensile strength: see specification table below).
