What are the advantages of using E Type Rail Elastic Clips?
E-type rail elastic clips demonstrate significant advantages in multiple aspects within railway track systems, with their core value lying in exceptional durability and reliable holding force.
Manufactured from high-quality spring steel 60Si2MnA and subjected to precise heat treatment, the clips maintain a stable hardness within the ideal range of 44-48 HRC. This characteristic ensures stable clamping force is maintained even under long-term dynamic loads.

The fatigue life performance is particularly outstanding, with 18mm diameter specifications enduring 3 million cycles without fracture, and 20mm diameter specifications achieving 5 million cycles. This exceptional durability directly translates to longer maintenance cycles and lower total lifecycle costs.

In terms of structural design, the unique shape of the E-type clip enables it to provide continuous and stable rail alignment force, effectively resisting longitudinal movement of the rail caused by temperature changes and train vibrations. Its compact design not only facilitates installation and maintenance but also adapts to various complex track structure conditions.
The systematic solution formed by the clip and its matching components, including the synergistic effect of insert shoulders, rail insulators, and rail pads, collectively ensures the long-term stability of track geometry, significantly reducing the risk of gauge variation and track deformation.
Another important advantage of E-type clips is their excellent environmental adaptability. By offering various surface treatment options, including plain (oiled), oxide black, and color painting, they can meet anti-corrosion requirements for all climatic conditions from humid coastal to arid inland areas.
