Lightweight pinion: warm forged
Pinions with large heads are used as input shafts of rear-axle differential transmissions, e. g. in pick-up trucks and other applications with high torques. In these applications, a suitable lightweighting solution is to produce a pinion whose head is hollow forged in a single pass on a warm forging press. This leads to a lighter part and a more cost-efficient process.
