What type of Rail Pad is used for 60KG rails?

 

A rubber rail pad is used for 60kg rails, typically made of natural rubber with a hardness of 75-85 shores A. These pads are installed between the steel rail and the concrete sleeper to absorb shock, reduce noise, and prolong the life of the track infrastructure.

 

• Material: Natural rubber is the main material, often with a hardness of 75-85 shores A.

 

• Function: The pad's primary role is to protect the sleeper and the track bed from the high-speed vibrations and impacts of passing trains.

 

 

• Additional benefits: It provides electrical insulation, shock absorption, and low noise performance.

 

• Types: Specific models exist, often identified by a standard drawing number, such as RDSO Drawing No. T-3711 for 60KG UIC rail sections.

 

• Application: These pads are used in industrial applications, on concrete foundations, and on steel structure foundations.

 

The Following are Rubber Rail Pads Parameters：

 

 

Type	Diameter(mm)	Weight(kg)	Material

WJ8-6	175mm*160mm	0.24kg	Premium natural rubber or synthetic rubber
P50	185mm*131mm*10mm	0.29kg	Premium natural rubber or synthetic rubber
P60	185mm*151mm*10mm	0.34kg	Premium natural rubber or synthetic rubber
WJ8-6	175mm*160mm	0.24kg	Premium natural rubber or synthetic rubber

 

Manufacturing Process
 

 

•	Preparation of rubber compound
•	Mixing is carried out on a two-roll mill or in an internal mixer. In the case of an internal mixer, it can be done in a single-stage or double-stage mixing where the masterbatch, which was earlier prepared in the internal mixer, is finalized by adding curatives on a two roll mill.
•	Shaping and curing
•	Compression or Injection moulding
•	Trimming of finished products
•	Ready for use

 

Rail pad functions

 

A rail rubber pad is essential in reducing shock and vibration in a rail system. The pad laid under the rail to ensure:

 

• Load distribution over a larger surface

 

• Elimination of load concentration and the resultant fatigue stresses

 

• Centering of loads on the supporting element

 

• Absorption of uneven contact surfaces between rail and support

 

• Reduction of noise and vibration

 

• Sealing between the bottom of the rail and the top of the support

 

• Reduction of wear of the rail and its support

 

 

Rail pad materials

 

We have developed a range of high-performance elastic rail pads for stiffness requirements and various application areas-from trams through standard gauge railways to heavy haul lines, especially those for E-type rail fastening systems and SKL type rail fastening systems with material of HDPE/EVA/Rubber, with following properties respectively.
