Metro Chevron Spring - Part 3128 0458 15

The 3128 0458 15 chevron spring is dimensioned for metro and light rail vehicle bogies on urban transit networks. Optimized for the speed range and tight-radius track geometry typical of metro systems, providing balanced ride comfort and curving performance. The lower free height compared to mainline variants reflects reduced axle loads of metro vehicles. Used by US transit systems including MTA New York, WMATA Washington DC, CTA Chicago, BART San Francisco, and MBTA Boston. EN 45545-2 fire certified. HAMM Mount supports US Buy American Act compliant transit procurement programs.

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.
