Axle suspension roller bearings

Axle suspension roller bearing supports are integrated in electric freight train locomotives in order to support the traction motor that is arranged transverse to the direction of travel. The motor rests directly on the wheel set shaft in two bearing units.

So that the axle suspension roller bearings achieve long operating life (nominal operating life of over 2 million kilometers), roller bearings with high load carrying capacity are used. High loads caused by vibrations and shocks are supported by special tapered roller bearings with reinforced sheet metal cages. Other designs with collars on the outer rings or with current isolation for example, are also available on request.
