What are the common dimensions of Rail Rubber Pads?
Common rail rubber pad dimensions vary, but typical thicknesses range from 7 mm to 10 mm, with standard lengths of 12 meters. Width is determined by the specific rail foot, with a tolerance of about 5 to 6 mm less than the rail's width.
| Rubber Rail Pad | ||
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
Common dimensions
- Thickness: 7 mm is a common nominal thickness, while others like 6.2 mm and 10 mm are also specified. The thickness can be specified with tolerances, such as +0.5 mm or -0.0 mm.
- Length: A standard length is 12 meters, though this can vary depending on the application and may be supplied with a tolerance of ± 50mm.
- Width: Pad width is customized to the specific rail. It is designed to be 5 to 6 mm less than the width of the rail foot.
Other considerations
- Material and reinforcement: Pads can be made from various materials like rubber, EVA, or a combination, and may include steel or nylon cord reinforcement for strength.
- Customization: While standard dimensions exist, pads can be manufactured to different sizes and specifications to meet special demands.
A rail pad plays an important role in reducing shock and vibration, the detailed functions lie in the following:
- Distribute the load that the trains pressed on the rails with a larger elastic surface.
- Reduce the noise that trains hitting on the rails and improve the comfort of the passengers.
- The use of rail pad can decrease the abrasion of rails and prolong the service life of rail track.
- The elasticity of rail pad can decrease the vibration
