Why are Rail Rubber Pads used in railways?
Rail rubber pads are used in railways to reduce vibration and impact, protect infrastructure, and provide electrical insulation between the rail and the sleepers. By absorbing shock, they minimize wear on the rails and sleepers, lower noise levels, and prevent stress concentration, ensuring a more stable and durable track structure.
| 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 |
Primary functions of rail rubber pads:
- Dampen vibration and impact: They absorb the shock from high-speed trains, which reduces the stress and fatigue on the rails and concrete sleepers.
- Protect infrastructure: By distributing the load from the train evenly across a larger surface, the pads protect the railway sleepers from concentrated forces and fatigue cracking.
- Reduce noise: The pads help to quiet the railway system by dampening the sound and vibrations generated by the train's movement.
- Provide electrical insulation: They prevent electrical currents from the signal system from flowing through the track, ensuring the safety and reliability of the signalling equipment.
- Mitigate wear and tear: They reduce wear on the bottom of the rail and the top of the sleeper, which extends the life of the track components.
- Seal against elements: The pads can also help seal the interface between the rail and the sleeper, protecting against moisture and debris.
GNEE RAIL is equipped with rail pad production lines for 130sets of machines, for the whole process of injection, refining rubber, sulfuration, moulding and inspection, etc. We own the most engineers for rail pad development, design, production and inspection, with annual production capacity reaching up to 2000, 000 pieces. What's more, rail pads for high speed rail lines are our featured products, including both the elastic rubber plates and height adjustment pads.
As a professional rail fastener manufacturer, GNEE RAIL can produce various types of rubber rail pads with different materials, such as natural rubber, EVA, HDPE and so on. Our EVA/HDPE/rubber rail pads are with high elasticity, applying to types for rails such as rail UIC54, UIC60, BS80lbs,BS100lbs, and sizes as ordered. The pads can be customized with or without grooves, in various possible designs, depending on customers' requirements.
