Rail Rubber Pads

Product Description

What is rail rubber pad

Rail rubber pad (also called rail pad) is made of elastic polyurethane pad and is installed between steel rail and concrete sleeper. It is an important part of the supporting structure of heavy crane rail tracks and railway tracks.

The function of railway rubber pads is to protect the sleepers from impact and extrusion. At the same time, railway rubber pads can electrically isolate the signal system. As railway rubber mats are always exposed to the atmosphere, they are required to have good resistance to natural aging, cold resistance, and heat resistance. In addition, railway rubber pads should have good shock absorption and low noise performance.

Detailed Product Information

Function of Rail Rubber Pad

1. Load distribution on a larger surface
2. Eliminate load concentration and the resulting fatigue stress
3. Focus the load on the support element
4. Absorb uneven contact surface between rail and bracket
5. Reduce noise and vibration
6. The seal between the bottom of the rail and the top of the bracket
7. Reduce the wear of steel rail and its support

Types of rail rubber pads

1. Rail pads for E-type rail fastener system
The rail rubber pad used in the E-rail fastening system has a similar function to the rail insulator, which can isolate the rail above it from the sleeper below it, effectively preventing vibration and structural noise. The rail pad, e clips, rail insulator and rail shoulder form a complete set of E-type rail fastening system.

2. Rail pad for SKL rail fastening system
The rail pad in the SKL rail fastening system is a small but important fastener component that works with SKL clips, screw spikes, plastic dowels, rail tie plates, etc. Rail rubber pads have a certain rigidity and significantly increase the elasticity of the rail superstructure. It has higher elasticity and helps rolling stock to run quietly to meet the acoustic requirements of today's railway lines.
