These highly sophisticated axlebox designs are tailored to
customer specifications and applied in all kinds of railway
vehicles. The axleboxes are made mainly of high-grade SG
spheroidal graphite iron which combines both endurance
characteristics and cost effectiveness.
Finite element method (FEM) computer calculations are made
to optimise the design and to pre-validate the fatigue life. The
next validation step of new axleboxes is done by fatigue testing
before starting field-testing under real operating conditions.
