Rubber Chevron Spring - Part 6129902

Part 6129902 is a heavy-duty rubber chevron spring engineered for mainline passenger train bogies. This component is widely used across European and North American rail networks where consistent ride quality and long service intervals are essential. The multi-layer chevron (V-spring) design distributes axle loads evenly while providing progressive spring characteristics that adapt to varying passenger loads. HAMM Mount manufactures the 6129902 using heat-resistant NR/SBR compounds that maintain their elastic properties from -45C to +85C across extreme continental climates. EN 45545-2 fire safety certified.

Manufactured by HAMM Mount in our ISO 9001:2015 certified facility using advanced vulcanization technology and premium rubber compounds. Every unit undergoes multi-stage quality control including dimensional inspection, hardness verification, and load-deflection testing. Fire safety compliance per EN 45545-2 is verified for all railway applications.
