Elastic Rail Clip E2007 Railway Fasteners Supplier China

The Elastic Rail Clip E2007 (also known as the E2007 E-clip) is a high-strength fastener used in railway track systems to securely fix steel rails to wooden or concrete sleepers. It is a critical component of the E-type fastening system, designed to maintain rail gauge and prevent movement by exerting a constant clamping force.

Key Technical Specifications

• Material: Typically manufactured from hot-pressed spring steel, such as 60Si2MnA, 60Si2Cr, or 38Si7.

• Dimensions: Common diameter is 16mm with a weight of approximately 0.45kg per unit. 20mm can also be available.

• Hardness: Ranges from HRC 42-48.

• Performance: Capable of a toe load exceeding 600kgf and a fatigue life of 3 to 5 million cycles without cracking.

• Surface Treatment: Options include plain oiled, oxygen black, zinc plated, hot-dip galvanized, or dacromet coating for corrosion resistance. 

Functions and Applications

• Fastening: Clamps the rail to the sleeper to prevent vertical and horizontal displacement.

• Vibration Absorption: The elastic deformation of the spring steel helps alleviate shocks and vibrations from moving trains.

• Versatility: Used globally in various rail sections for freight, passengers, and heavy-haul tracks.

• System Components: Typically used as part of an assembly that includes the clip, a rail shoulder, a rail pad, and insulators. 

Standards and Compliance

• Sigunm is able to comply with international standards such as GB/T 1222, DIN 17221, and ISO 9001:2015. Specialized versions like anti-theft/vandal-resistant clips are also available to protect railway infrastructure from tampering.
