Coil Springs
Amsted Rail spring manufacturing is differentiated by its excellent process control, which assures consistency of dimensional, metallurgical and functional properties in final products. Our engineers have extensive experience in custom designing springs for the most demanding requirements. All Amsted Rail spring manufacturing processes include shot-peening and heat-treating.
Increasing loads demand stronger springs
Over the past 75 years, the average freight car weight in North America has increased from approximately 70 tons to 110 tons. Axle loads globally reflect a similar trend and are rapidly approaching North American capacity levels. As heavy haul operators continue to increase carrying capacity to reduce freight transportation costs, no spring provider in the world can match Amsted Rail’s capabilities to manufacture the springs essential to optimize railcar performance.
Superior process. Superior productivity.
Amsted Rail’s innovative, cost-effective manufacturing process guarantees delivery of the highest quality springs in the shortest possible turnaround time. These advantages are significantly magnified when every railcar requires 50 to 60 springs to provide superior ride performance under today’s burgeoning axle loads.
