W3 W12 W14 Clip Fasteners System

The railway fastener system is a collection of technical equipment to achieve reliable connection between rails and sleepers. It consists of fastening elements, anti-loosening devices, and buffer components. It can be divided into high elasticity type, high insulation type, and high wear resistance type according to the performance optimization direction.

The high wear resistance SKL heavy-duty fastener uses surface hardened alloy steel spring bars. When subjected to the rolling of trains with an axle load of more than 30 tons, the component wear rate is reduced by 40%. From the manufacturing process, the spring bars are precisely forged and heat treated to enhance the mechanical properties, the bolts use rolled threads to improve fatigue resistance, and the pads are vulcanized to achieve a firm combination of rubber and metal. Through targeted performance optimization, the system effectively solves the problems of vibration, electrical safety, and component loss in track connections, and significantly improves the reliability and economy of railway transportation.

The SKL fastener system is a standardized connection solution developed based on the needs of railway engineering practice. It generates a continuous and stable buckle pressure through the elastic deformation of the spring bar, and cooperates with the insulation and buffering performance of the rail pad to ensure the reliable connection between the rail and the sleeper.

The system spring bar adopts 60Si2CrA spring steel, which has excellent fatigue resistance after isothermal quenching treatment. The rail pad is reinforced with wear-resistant particles, which extends the service life by 2 times.

In actual application, W3 adopts a wavy pad design, which can reduce noise by 12dB when the subway passes through residential areas; W12 fine-tunes the spring bar parameters to meet the strict requirements of high-speed rail for track smoothness; W14's modular design can quickly combine different components to meet diverse construction needs;
