NSK QT Series

Gear unit bearings are used to facilitate the smooth transmission of rotating force to the axles under vibration during train operation. The bearings are usually operated under harsh conditions. The reaction forces from the mating gears as well as the inertia force of the pinion shaft and the gearbox are applied to the gear bearings.
