The raid pad prevents rail-sleeper abrasion and the crushing of the sleeper under the rail foot. Rubber rail pads are normally designed to a specified load-deflection characteristic. The initial stiffness of the rail pad is designed to be low, their deformations under the springs toe loads is quite substantial. This special design keeps the rail pad remains in intimate contact with the rail despite any vertical movements of the latter.
When the wheel is over the pad, the latter's stiffness must prevent large movements, so as to prevent metal spring becoming loose. Such a load-deflection characteristic can be obtained by introducing grooves in the rubber rail pads.

Our railway pads have a wide range of materials and types, such as rubber rail pad, HDPE rail pad, EVA rail pad, crane rail pad, etc. And there are two patterns for your selection- grooved or studded. They are suitable for various models of high-speed rails, regular rail, and crane rail.
Application of Railway Pads in SKL Fastener Systems
A rail pad in a SKL rail fastening system is a small but crucial fastener part, working together with SKL clips, screw spikes, plastic dowels, guide plates and so on. The elastic rail pads we produce possess a defined stiffness and demonstrably increase the elasticity of the track superstructure. With a higher level of elasticity, it contributes towards quiet running of the rolling stock, to meet today's acoustic requirements on railway lines.
