At Anping County Boli Hardware Wiremesh Products Factory, we have been manufacturing high-quality industrial components since 1998. Our Nylon Sleeve for Concrete Sleepers is engineered to meet the demanding requirements of railway infrastructure. Made from PA6 material with an M30 thread, this sleeve delivers a 200kN compression capacity and complies with EN standards, ensuring reliable performance in track fastening systems. With annual exports exceeding US$5 million, our products are trusted by customers across North America, Europe, Asia, and more.
This product is specifically designed for use with concrete sleepers (railway ties) to provide secure anchorage and vibration damping. The PA6 nylon offers excellent tensile strength, wear resistance, and chemical stability, making it suitable for harsh outdoor environments. The M30 thread allows for easy integration with standard bolts and fasteners, while the 200kN compression rating guarantees durability under heavy loads.
Key Features & Benefits
- High Load Capacity: With a compression strength of 200kN, the sleeve withstands substantial axial forces in railway applications.
- PA6 Nylon Material: Offers excellent mechanical properties, including high impact resistance, low friction, and good fatigue endurance.
- M30 Thread Precision: Manufactured to tight tolerances, ensuring easy assembly and consistent clamping force.
- EN Standard Compliance: Manufactured in accordance with European Norms, providing confidence in quality and interoperability.
- Weather & UV Resistance: PA6 is inherently resistant to moisture, chemicals, and UV radiation, ideal for outdoor railway tracks.
- Customizable Options: Color, packaging, and specific dimensions can be tailored to customer requirements.
