SKF and ContiTech Air Spring Systems have developed a unique axlebox suspension system for railway bogies that substantially reduces maintenance needs and costs. The solution is an integration of rubber springs and hydraulic dampers into the axlebox.

The new system, designed for freight cars with 25-tonne axle loads, is dimensioned for a maintenance interval of 1 million kilometres, which corresponds to 10 years of use.

ContiTech manufactures components and complete systems for self-regulating air springs in commercial vehicles, buses and rail vehicles as well as stationary machines and foundations.
