Railway elastic clip is a core component in track fastening systems. It firmly secures rails to sleepers while effectively absorbing vibrations and impacts from train operations, ensuring long-term track stability.
Made from high-strength spring steel with a hardness of 44-48HRC, the clip provides excellent elasticity, toughness, and fatigue resistance, maintaining rail stability under high-frequency train loads and preventing loosening and track wear. Its design ensures tight fit with sleepers and adapts to various climates and environments.
