Forged Pinions & Pinion Shafts
A pinion is a shaft and a gear in one part, which means it must resist torsional fatigue along its length and contact fatigue at its teeth. Integrally forging the head and shank avoids the joint that a two-piece design would have to trust.

One-Piece Head and Shank
The gear head is upset from the shank in a controlled sequence, so grain flows from the shank into the tooth region without interruption. On differential pinions carrying full drive torque through a small tooth count, that continuity is decisive.
Case Hardening Response
20MnCr5, 16MnCr5 and EN353 blanks are forged with a controlled finish temperature so case depth after carburising stays consistent piece to piece — the property gear shops care about most when they receive blanks from a new supplier.
- Uniform hardenability
- Consistent case depth response
- Controlled finish temperature
- Traceable to heat number
Machining Allowance
Blanks are supplied with an allowance matched to your tooth cutting and grinding route, keeping stock removal light without risking under-size after distortion.

Questions Answered
Do you supply pinion blanks or finished pinions?
+
Blanks, proof machined to your allowance. Tooth cutting is generally done by the gear manufacturer.
Why forge the head integrally?
+
A welded or assembled head introduces a joint at the highest-torque location. Integral upsetting keeps grain continuous from shank to teeth.
What supply hardness do you provide?
+
Normalised or annealed to the band your machining process prefers, typically 180–220 BHN.
Can you meet a specific case depth after carburising?
+
We control forging and normalising so hardenability is uniform; the carburising cycle itself is set by your heat treatment specification.
