Usage
Concrete Sleepers
At Anping County Boli Hardware Wiremesh Products Factory, we are committed to delivering precision-engineered fastening components for the global railway industry. Our Nylon Sleeve for Concrete Sleepers is manufactured from 100% virgin nylon with a controlled density of 1.14 g/cm³, ensuring consistent performance under heavy-duty rail fastening conditions. With over two decades of manufacturing experience (since 1998) and annual export values of US$5–10 million, we offer reliable solutions trusted by markets across North America, South America, Europe, Asia, and Africa.
This sleeve is specifically designed to withstand the intense mechanical stresses and environmental challenges of modern railway systems. The use of virgin nylon guarantees superior mechanical properties, including high tensile strength, excellent impact resistance, and long-term dimensional stability. Whether you are maintaining existing tracks or constructing new high-speed lines, our nylon sleeve provides a cost-effective, durable fastening solution.
Key Features
- 100% Virgin Nylon Material – No recycled content, ensuring maximum purity and consistent mechanical properties. This eliminates the risk of premature failure caused by impurities or inconsistent polymer chains.
- Precise Density of 1.14 g/cm³ – Optimized for strength-to-weight ratio. This density provides excellent load-bearing capacity while keeping the sleeve lightweight for easy handling and installation.
- Heavy-Duty Performance – Designed to endure high clamping forces, vibrations, and dynamic loads common in heavy-haul and high-speed rail applications.
- Excellent Wear & Abrasion Resistance – Nylon’s natural low coefficient of friction reduces wear on both the sleeve and the rail clip, extending service intervals.
- UV & Chemical Resistance – Suitable for outdoor use in diverse climates, including exposure to sunlight, moisture, oil, and de-icing chemicals.
- Easy Installation – The sleeve features a smooth inner bore and precise outer diameter, compatible with standard concrete sleepers and rail fastening systems.
- Customizable Dimensions – Available in various lengths, inner diameters, and wall thicknesses to match specific rail profiles and fastening designs.
