Grooved rubber sole plate
- Commodity name： Grooved rubber sole plate
- Description
-
A rail pad, also called rail sole plate, rail rubber plate, is designed between the rail tie plate and rail foot, made by an elastic polyurethane mat, which is interposed between steel rails and tie sleepers to protect the sleeper top from wearing and impacting. Its defined stiffness is used to increase the elasticity of the ballast superstructure and reduce vibration and shock in the railway system.
The rail rubber pad is always fastened within a fastening system by rail anchor bolts or screw spikes into the sleeper ties. The reason that rail pad made up of rubber or plastic is to dampen the vibration or shocks of a passing train. Usually the starting stiffness is designed a little low in order that the relative deformation under the spring clip toe loads is generous, which can guarantee the rail pad maintaining in close contact with the rail in spite of any vertical movements of the latter.
Kunshan Alex Railway Fastening Co.,Ltd are specialized in various types of railway elastic rubber products, such as rail pads and rail boots/shoes, as well as insulated plastic products(rail insulators, rail plastic dowel ). With our rubber vulcanizers and injection molding machines, as well as various advanced testing equipment, we have an annual production capacity of 8,000 tons. According to customer requirements, we can provide various rubber products as OEM or ODM.
