Rail elastic clip is one of the popular fastening parts to keep rail track fixed on rail sleepers(wooden sleeper and concrete sleeper). Rail clamps are also used in some rail fastening systems.
E-type rail clip can provide durable alignment which can protect the steel rail and the fastenings from high pressure. The materials of e clip is spring steel which make e clip of high strength. There are many types of e clip: E1609, E1809, E1817, E2007, E2009, E2055, etc.
| Model | Diameter | Material | Under Pressure | HRC | Weight |
| E1609 | Ø 16mm | 60Si2MnA | ≥950kg | 44-48 | 0.43kg/pc |
| E1809 | Ø 20mm | 60Si2MnA | ≥950kg | 44-48 | 0.61kg/pc |
| E1813 | Ø 18mm | 60Si2MnA | ≥950kg | 44-48 | 0.62kg/pc |

How to restore elasticity of E rail elastic clip?
Generally cannot restore the elasticity of a worn-out E-rail clip; they lose their springiness due to repeated stress, fatigue, and corrosion, requiring replacement with new, properly manufactured clips, though proper maintenance like lubrication and corrosion protection can extend the life of new clips. If a clip is just stiff from being stuck, specialized tools help remove and reinstall them, but if the material itself is fatigued, it's time to swap it out.
Why Elasticity is Lost:
Fatigue: Repeated bending and twisting from passing trains causes microscopic cracks and weakens the steel.
Corrosion: Rust eats away at the metal, reducing its cross-section and strength.
Overstress: High impact loads or improper installation can permanently deform the clip.
What is the lifespan of an e-rail clip?
An e-rail clip's lifespan is typically designed for around 5 million load cycles, but real-world life varies greatly, ranging from a few years (e.g., 2.5 years for pads in high-speed) to potentially millions of cycles, depending heavily on factors like train speed, track condition (corrugation), rail pad quality, and applied loads, with failure usually due to fatigue cracks at high-stress points.
GNEE RAIL offer an extensive range of rail clips with optimum quality, these rail clips are designed with high precision and made up of premium grade spring steel. GNEE has been the largest and most competitive production base of rail clip in China after more than 18 years' rail clip producing experience, and have qualification to tender nationally large and medium scaled rail projects. What's more, our rail clip can be customized according to clients' requirements.
