A dual-layer railway washer is a specialized fastening component used in railway track fastening systems. Featuring a dual-layer design, it primarily serves to connect and interface various railway fastening elements, providing reliable support for bolted fastening structures.
Unlike conventional flat railway washers, this dual-layer variant is characterized by its distinct two-layer structure, which allows it to meet specific installation, interfacing, and fastening requirements tailored to the design of a given track fastening system.
Product Function
- Reliable Anti-Loosening and Self-Locking: Designed for environments characterized by high-frequency vibration and alternating impact—typical of railway tracks—this system prevents nuts from rotating loose, maintains stable bolt preload, and reduces the risk of fastener loosening.
- Cushioning and Vibration Absorption: The wedge-shaped structure provides controlled elastic compensation, offsetting any loss in preload caused by load fluctuations.
- Protection of Contact Surfaces: The design helps distribute pressure, minimizing surface damage (such as indentations or scoring) to base plates and rail components caused by the nut.
- Superior Fatigue Resistance: Compared to standard single-layer spring washers, the dual-layer wedge-shaped structure offers enhanced resistance to vibration-induced fatigue, making it well-suited for long-term service on heavy-haul, high-vibration railway lines.
Our company supplies dual-layer wedge-type anti-loosening washers that meet both Chinese national standards and international export standards. We offer OEM and ODM customization services, with the capability to develop products based on client drawings or specific requirements for overseas projects. We can also provide complete fastening system sets—including rail clips, screw spikes, nuts, and flat washers—suitable for conventional railways, heavy-haul railways, metro systems, and international railway projects.
