Why are Rail Pads divided into two categories: Grooved Rail Pads and Studded Rail Pads?

 

Rail pads are divided into grooved and studded types to manage different design needs and performance characteristics for a track system. Grooved pads are designed to increase stability and prevent wear on the pad itself by keeping the rail in close contact with the pad, often incorporating a steel sheet for enhanced lateral stiffness. Studded pads, with their studded surface, focus on providing superior impact absorption, noise suppression, and passenger comfort, and are especially beneficial for higher-speed or high-load applications.

 

 

Grooved rail pads

 

• Function: The grooves on the top surface ensure the rail maintains constant contact, which reduces wear on the rubber pad itself.

 

• Construction: They are often made with a thin steel sheet in the middle to provide extra lateral stiffness, helping to stabilize the rail.

 

• Benefit: This design helps with durability and maintains a good contact interface between the rail and the pad, particularly for applications where the rail is consistently supported.

 

 

Studded rail pads

 

• Function: The studded design is engineered to be highly resilient and provides excellent shock and vibration absorption.

 

• Construction: They are made from a variety of natural and synthetic elastomers.

 

• Benefit: Studded pads are highly effective at reducing impact forces, suppressing noise, and improving passenger comfort, making them a common choice for high-speed and heavy-haul applications.

 

 

The rail pad laid under the rail is used to guarantee

 

• The load distribution covering a larger surface area

 

• Reducing load concentration and usage fatigue stress

 

• Even contact area between the rail and supporting components

 

• Reducing noise and structural vibrations

 

• Sealing function between the top support and rail bottom

 

• Reducing rail wearing and relevant supporting components

 

 

As a professional rail fastener manufacturer, GNEE RAIL can produce various types of rubber rail pads with different materials, such as natural rubber, EVA, HDPE and so on. Our EVA/HDPE/rubber rail pads are with high elasticity, applying to types for rails such as rail UIC54, UIC60, BS80lbs,BS100lbs, and sizes as ordered. The pads can be customized with or without grooves, in various possible designs, depending on customers' requirements.
