20mm E Type Clips Fasteners System

E Type Clips Fasteners System is an important device for maintaining precise geometric shape of railway tracks. Through the reasonable configuration of various components, it ensures that the rails do not move under train loads. E-type spring clips are available in 18mm, 20mm and other specifications. After precision forging and strict testing, they form a stable buckle pressure. For example, E1609 is suitable for lightly loaded lines, and E2009 is used for heavy-loaded lines. The rail shoulder is made of QT450-10 ductile iron, and the internal stress is eliminated through aging treatment to ensure that it will not deform after long-term use; the surface of the HDPE rail pad is designed with anti-slip texture to increase the friction with the rails and sleepers and prevent the pad from shifting; the rail insulation is formed by a special injection molding process, with high insulation resistance, which can effectively prevent the corrosion of the track structure by stray current, and is widely used in railway construction and maintenance projects.

20mm spring clip is a specification of spring clip in E-type railway fastener system.

Spring clip: E-type spring clip, with a diameter of 20mm, is generally made of spring steel, such as 60Si2MnA, etc., and obtains good strength, toughness and fatigue resistance after heat treatment. Its shape is designed to be E-type, and it can buckle the rail by generating buckling pressure through elastic deformation.

Greater buckling pressure: Generally speaking, the toe load (toe load, which can reflect the buckling pressure-related performance) of 18mm spring clip is 750-900kgf, while the toe load of 20mm spring clip can reach 1100-1400kgf. Greater buckling pressure can more effectively fix the rail and prevent the rail from longitudinal and lateral displacement. It is more suitable for heavy-load railways or lines with high requirements for track stability, which can better ensure the stability of track gauge and improve driving safety performance.

Better structural stability: Spring bars with larger diameters are less likely to deform and be damaged when subjected to various forces (such as bending, torsion, impact, etc.) generated by train loads. They have higher structural stability and may have stronger fatigue resistance.

In railway infrastructure construction, a reliable fastening system is an important guarantee for ensuring the long-term stability of the track. GNEE RAIL focuses on this key area, and its product line covers core components such as high-performance spring clips, special connection bolts, and insulating gaskets. Through continuous optimization of production processes and strict quality control, our products have excellent performance in vibration resistance and wear resistance.
