High-Quality Plastic Parts Suppliers in China - Angle Gauge Plates, EVA Rail Pads, and More from Our Factory
Basic Information
These standard-compliant rail pads are core elastic components installed between the rail foot and base plate, responsible for absorbing wheel-rail impact, reducing vibration transmission and avoiding metal wear between contact surfaces.
Customized Materials
- EPDM Rubber: Ideal for general heavy-haul and commuter lines.
- Thermoplastic Polyurethane (TPU): Designed for 300km/h+ high-speed rails.
- High-Hardness Nitrile Rubber: Engineered for North American 40t axle load heavy-haul freight lines (AREMA Chapter 5).
Core Performance
- Impact Absorption: 25%~70% adjustable rate.
- Durability: < 10% permanent compression deformation after 10 million load cycles.
- Temperature Range: Operating capability from -40℃ to 70℃.
- UV Resistance: 500+ hour UV aging resistance for open-air lines.
Compatibility & Options
- Fastening Systems: Fully compatible with Pandrol Fastclip, Vossloh SKL series, and AREMA tie plate systems.
- Customization: Adjustable thickness, hardness, and surface texture.
- Noise Reduction: Low-damping versions reduce vibration by up to 15dB for urban transit.
Frequently Asked Questions (FAQ)
Q: What materials are used to manufacture these rail pads?
They are made from three customized materials: EPDM rubber for general heavy-haul and commuter lines, thermoplastic polyurethane (TPU) for high-speed rails (300km/h+), and high-hardness nitrile rubber for North American 40t axle load heavy-haul freight lines.
Q: What is the operating temperature range and environmental resistance of the rail pads?
The rail pads operate reliably within a temperature range of -40℃ to 70℃ and feature 500+ hour UV aging resistance, making them highly durable for open-air lines.
Q: How do these rail pads perform under long-term load cycles?
They exhibit excellent fatigue resistance, showing less than 10% permanent compression deformation after 10 million load cycles, with an adjustable impact absorption rate of 25%~70%.
Q: Are these rail pads compatible with standard fastening systems?
Yes, they are fully compatible with mainstream standard fastening systems, including Pandrol Fastclip, Vossloh SKL series, and AREMA tie plate systems.
Q: Can the rail pads be customized for noise-sensitive areas?
Yes, low-damping customized versions are available for noise-sensitive urban transit lines, which can cut vibration transmission to surrounding areas by up to 15dB. Thickness, hardness, and surface texture are also customizable.
Q: Do you provide compliance documentation for railway operations?
Yes, each batch of rail pads is supplied with material test reports and compliance certificates to meet local railway operation approval requirements.
