As a leading manufacturer with over 25 years of experience in railway hardware, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Elastic Rail Clip designed specifically for high-speed rail turnout systems rated for 350 km/h operation. Our factory, established in 1998, has exported millions of rail fastening components to global markets including North America, Europe, Southeast Asia, and Oceania, with annual export value exceeding US$5 million. This rail clip is engineered to deliver superior clamping force, exceptional fatigue life, and long-term reliability under the demanding conditions of high-speed railway turnouts.
The elastic rail clip is a critical component in modern railway track infrastructure. It securely fastens the rail to the baseplate while maintaining the necessary elasticity to absorb dynamic loads from passing trains. Our clips are manufactured from premium spring steel, heat-treated to achieve optimal hardness and toughness, ensuring consistent performance even at extreme speeds of 350 km/h. With precise dimensional tolerances and a robust anti-corrosion finish, these clips offer easy installation and minimal maintenance, making them the preferred choice for high-speed rail projects worldwide.
Key Features & Technical Specifications
- Advanced Material: Made from high-quality spring steel (60Si2Mn or equivalent), with uniform microstructure for consistent elastic properties.
- Heat Treatment: Quenched and tempered to achieve a hardness of 40-48 HRC, balancing strength and ductility.
- Elastic Clamping Force: Designed to provide a clamping force of 8-12 kN per clip, ensuring stable gauge retention under high-speed dynamic loads.
- Fatigue Life: Tested to withstand over 5 million cycles without failure, meeting the demanding requirements of 350 km/h operational environments.
- Corrosion Protection: Surface treated with black oxide or optional zinc-plating to resist rust in humid or coastal conditions.
- Dimensional Precision: Manufactured to ±0.5 mm tolerance, ensuring compatibility with standard UIC / TB rail fastening systems.
- Easy Installation: Designed for use with standard insertion tools and automated tamping machines, reducing labor time.
- Low Maintenance: Self-locking design prevents loosening; no need for frequent re-tightening.

Our elastic rail clips offer distinct advantages for high-speed rail turnout systems. The optimized geometry ensures uniform stress distribution across the rail base, reducing the risk of rail rollover and improving ride comfort. The high fatigue resistance minimizes replacement frequency, lowering total lifecycle costs for railway operators. Additionally, the clips are compatible with various baseplate designs (e.g., standard UIC60, 54E1 profiles) and can be customized to meet specific project requirements.

Frequently Asked Questions (FAQ)
-
What material is the elastic rail clip made of?
Our clips are manufactured from high-grade spring steel (60Si2Mn or equivalent), which provides excellent elasticity and fatigue resistance. -
Can these clips be used for speeds above 350 km/h?
While designed for 350 km/h, they have been tested for dynamic loads corresponding to higher speeds. Please consult our engineering team for specific project requirements. -
How long is the service life of the clip?
Under normal operating conditions and proper maintenance, the clip can last more than 10 years, with a fatigue life of over 5 million cycles. -
What surface treatment options are available?
Standard is black oxide. We also offer zinc plating, Dacromet coating, or other anti-corrosion treatments upon request. -
Do you provide custom dimensions or shapes?
Yes, we can customize the clip dimensions, clamping force, and geometry according to your baseplate design or specific turnout system. -
What is the minimum order quantity (MOQ)?
Our MOQ is 1000 pieces for standard sizes. For custom designs, it may vary; please contact us for details. -
How do you ensure quality consistency?
We have a comprehensive quality control system including raw material inspection, dimensional measurement during production, hardness testing, and final visual inspection. Each batch is accompanied by a test report. -
