Product Details



Rubber buffer springs are very heavy duty composite blocks which undergo very heavy compressive & shear loads during operation.

The spring rate ,compression ratio, etcof the springs are decided with respect to the type of vehicle (i.e. Locomotive/Passenger/Freight)


The typical construction consists of 4 or more metal elements interleafed with rubber bonded between them.The buffers springs form part of the secondary suspension of the bogies, and are vital safety components essential for a smooth ride quality & efficient operation.
