The E-type rail clip is a core component that provides continuous elastic clamping for the track system. It achieves self-tightening by engaging with a parallel lug structure on the sleeper. Its clamping force can be adjusted based on the model (e.g., 13–18 kN for the E2009 type, 10–15 kN for the E1809 type), effectively resisting lateral displacement and overturning of the rail. Additionally, it absorbs train vibrations through elastic deformation, reduces wear on track components, and ensures the smoothness and safety of continuously welded rail tracks.

The E 2055 rail clip is specifically designed to provide effective and reliable fastening for various types of rail sections. It is commonly used in heavy-haul railway applications, where the track undergoes significant loads and stresses. The clip is manufactured using high-quality materials, such as spring steel, which offer excellent strength and durability.
What is the hardness compliance value of the e2055 rail clip?
The hardness compliance value for an E2055 rail clip typically falls within the range of 42-48 HRC (Rockwell Hardness C scale), with common specifications citing 44-48 HRC or 42-47 HRC, depending on the specific material grade (like 60Si2MnA or 55SiMn) and manufacturer, balancing high strength with necessary elasticity for rail fastening.
Key Hardness Ranges:
44-48 HRC: A frequently cited range for E2055 clips.
42-47 HRC: Another common specification, often linked to materials like 60Si2MnA.
| Item | Diameter | Material | Weight | HRC Under pressure | Fatigue test |
|---|---|---|---|---|---|
| E2055 | ø20 | 60Si2MnA, 60Si2Cr, 55Si2Mn, 38Si7 | 0.80 kg | 44-48 | ≥950kg 5000000 times without breaking |
Why This Range?
Material Properties: These clips are made from spring steel alloys (e.g., 60Si2MnA, 60Si2CrA) that require specific heat treatment to achieve the desired hardness for performance.
Application: The hardness ensures the clip has sufficient clamping force (toe load) and fatigue life (millions of cycles) to securely hold rails under heavy train traffic.
What is the function of the e2055 rail elastic clip?
- Secures Rails: Provides constant clamping pressure to hold the rail base firmly to the sleeper/tie plate.
- Maintains Stability: Stops rails from moving horizontally (creep) and vertically, crucial for track integrity.
- Absorbs Forces: Its spring steel construction absorbs dynamic forces and vibrations from passing trains.
- Reliability: Offers a "fit-and-forget" solution with a long service life, reducing maintenance needs.
- Versatile: Used in various applications, from heavy-haul to metro and high-speed lines.
