Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with annual export value exceeding US$5 million. Our railway spring clip for sleepers in high-speed rail turnouts is engineered with precision, featuring a 14mm diameter, 8kN clamping force, and made from high-quality 60Si2Mn steel. This product ensures reliable rail fastening in demanding turnout environments, delivering consistent performance and long service life. Backed by over two decades of manufacturing experience, we offer a solution that combines strength, durability, and cost-effectiveness.
Key Features & Technical Specifications
- Material Excellence: Manufactured from 60Si2Mn spring steel, known for its high fatigue resistance and elastic recovery. This material ensures the clip maintains its clamping force over millions of cycles.
- Precise Diameter: 14mm rod diameter offers an optimal balance between flexibility and rigidity, suitable for standard sleeper fastening systems.
- Clamping Force: 8 kN (approximately 800 kgf) per clip provides secure rail fixation, preventing lateral displacement and reducing track maintenance.
- High-Speed Rail Compatibility: Designed specifically for turnouts on high-speed lines where dynamic loads are severe. The geometry and heat treatment are optimized for vibration resistance.
- Corrosion Protection: Standard surface treatment with black oxide or oil coating; other options (e.g., zinc plating, Dacromet) are customizable upon request.
- Easy Installation: Compatible with common rail fastening systems, allowing quick assembly and replacement without special tools.

Frequently Asked Questions (FAQ)
-
Q: What is the exact material grade of your spring clip?
A: We use 60Si2Mn according to Chinese standard GB/T 1222, which is equivalent to similar spring steel grades like SUP7 or 51CrV4, but with slightly different composition. Please check your local standards for equivalency. -
Q: Can you provide samples for testing before bulk order?
A: Yes, we offer samples at cost price. Sample lead time is typically 5–7 working days. Shipping cost is on the buyer's side, but we can help arrange. -
Q: What is the minimum order quantity (MOQ)?
A: For standard clips, MOQ is 500 pieces. For customized versions, MOQ may be higher. Please discuss with our sales team. -
Q: How do you ensure the clamping force is 8 kN?
A: Each clip is tested on a calibrated force gauge during production. We also provide a test certificate upon request. -
Q: Is this clip suitable for concrete sleepers?
A: Yes, it is designed for use with standard rail fastening systems on concrete sleepers in high-speed turnouts. However, please confirm the specific rail profile and insulator dimensions. -
Q: What surface treatments are available?
A: Standard is black oxide or oiled. Alternatives like zinc plating, Dacromet, or hot-dip galvanizing are available as customization. Note that some coatings may affect fatigue performance. -
Q: Do you export to my country? (e.g., Brazil, Germany, etc.)
A: We ship globally. Our main markets include North America, South America, Europe, Africa, Asia, and Oceania. Please provide the destination port for a shipping quote. -
Q: Can you make clips with a different diameter or clamping force?
A: Yes, we can customize the diameter (e.g., 13mm, 16mm) and adjust the clamping force by changing the geometry or material. However, tooling modification may be required. Contact us with your requirements.
