As a specialized manufacturer with over 25 years of experience (established in 1998), Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Nylon 66 Rail Clip Insert with 304 Stainless Steel Core, designed to deliver a reliable 2000N clamping force for railway track fastening systems. This product combines the durability of high-grade Nylon 66 with the strength of a 304 stainless steel core, ensuring long-lasting performance in demanding rail environments. By integrating advanced materials and precision engineering, we provide a solution that enhances track stability, reduces maintenance, and supports safe and efficient rail operations.
Our rail clip insert is crafted to meet the rigorous requirements of modern railway infrastructure. The Nylon 66 outer body offers excellent wear resistance, electrical insulation, and vibration dampening, while the 304 stainless steel core provides exceptional corrosion resistance and mechanical strength. With a consistent clamping force of 2000N, this insert ensures secure rail fastening even under heavy loads and dynamic conditions. It is suitable for use in various rail systems, including mainline tracks, metro lines, and industrial railways.
Key Features & Technical Specifications
- Material Composition: Outer body made of high-performance Nylon 66 (PA66) with glass fiber reinforcement (optional); inner core of 304 stainless steel for added strength.
- Clamping Force: Precisely calibrated at 2000N to ensure stable rail positioning and prevent loosening caused by vibration or thermal expansion.
- Corrosion Resistance: The 304 stainless steel core resists rust and chemical attack, making it ideal for outdoor use in humid, coastal, or industrial environments.
- Insulation Properties: Nylon 66 provides electrical insulation, reducing the risk of signal interference in electrified rail systems.
- Temperature Range: Operates effectively from -40°C to +120°C, maintaining mechanical properties in extreme climates.
- Customizable Dimensions: Available in standard sizes or tailored to fit specific rail profiles (e.g., 60kg/m, 50kg/m, etc.) upon request.
- Easy Installation: Designed for simple insertion into standard rail clip assemblies, reducing labor time and costs.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of using Nylon 66 instead of regular plastic?
A: Nylon 66 offers superior mechanical strength, wear resistance, and thermal stability compared to standard plastics. It also provides electrical insulation, which is critical for signaling systems in electrified railways. -
Q: Can this rail clip insert be used in high-speed rail applications?
A: Yes, the 2000N clamping force and robust materials make it suitable for high-speed lines where consistent rail fastening is essential. However, we recommend verifying compatibility with your specific rail profile and system. -
Q: Is the 304 stainless steel core resistant to saltwater corrosion?
A: 304 stainless steel has good resistance to saltwater and many chemicals, but for extremely aggressive environments (e.g., direct marine splash), we can discuss alternative materials like 316 stainless steel upon request. -
Q: What is the typical lifespan of this product?
A: Under normal operating conditions, the insert can last 5–10 years or more, depending on traffic load, climate, and maintenance. The Nylon 66 body is UV-stabilized for outdoor use. -
Q: Do you offer custom sizes or colors?
A: Yes, we can customize dimensions, clamping force, and color (e.g., for track identification) based on your drawings or samples. MOQ may apply for custom orders. -
Q: How is the product packaged for export?
A: Typically, we pack the inserts in sturdy cartons, then on pallets with shrink wrap. For large orders, bulk packaging in wooden crates is available. We can also customize packaging per your requirements. -
Q: Can you provide samples before mass production?
A: Absolutely. We offer free samples (shipping cost covered by buyer) for evaluation. Please contact our sales team to arrange sample delivery. -
Q: What is the lead time for a standard order?
A: Standard lead time is 15–25 days after confirmation of order and payment. For urgent orders, we can expedite with prior arrangement.
