W14 SKL14 Rail Elastic Clip For Railway Fastening
As one of the common railway fasteners in rail fastening system, elastic railway clips are made of forged spring steel and have many applications in railroad.
No matter as a part of railway fastening system or as a railway fastener, elastic railway clips are used together with other railway components, such as rail spike, rail tie plate, rail pad and rail plastic dowel.
W14 SKL14 Rail Elastic Clip
The W14 Rail Elastic Clip is an indispensable high-performance rail clip in railway fastening systems, specifically designed to maintain a secure connection between the rail and the sleeper, ensuring smooth and safe train operation under high-speed and heavy-load conditions.
The SKL14 Tension Clamp, with its unique design and high-quality materials, offers significant advantages in railway operations. Its high fatigue resistance allows it to withstand the dynamic vertical vibrations from passing trains, while the constant tension ensures that the clip and bolts remain secure. The central curved section prevents plastic deformation of the arms, achieving truly maintenance-free performance.
This system not only effectively prevents rail creep but also enhances the safety and durability of the track, making it particularly suitable for high-speed railways, urban transit lines, port crane rails, and industrial railway applications under heavy-load conditions.
W14 Rail Elastic Clip Technical Parameters
SKL14 Rail Elastic Clip can be manufactured from multiple high-performance spring steels, including 60Si2MnA, 60Si2CrA, 55Si2Mn, and 38Si7.

60Si2MnA offers excellent hardness and rebound performance due to its high carbon and silicon content, making it suitable for heavy-load and high-fatigue environments.
60Si2CrA, with higher chromium content, provides superior corrosion and wear resistance, ideal for coastal or high-humidity environments.
55Si2Mn balances strength and toughness, making it suitable for general railway and industrial lines.
38Si7 has moderate hardness, good elasticity, and plasticity, fitting for light-load or low-frequency railway applications.
These materials undergo precise heat treatment, achieving a hardness of HRC42–47, and can withstand ≥5 million fatigue cycles without cracking or plastic deformation, ensuring long-term stability and high reliability.
