About this part
What it is and why it is made that way
Die casting is how a complex gear shape is made economically — the cavity forms the teeth, the shoulders and the web in a single shot. The teeth are then cut or shaved to get the accuracy a transmission needs, and the bore is machined to the shaft fit. The result keeps the casting economics without giving up the running accuracy.
- Complex tooth form formed directly in the die
- Tooth flanks cut or shaved after casting for running accuracy
- Bore machined to the shaft fit
- Aluminium and zinc alloy options with material certificate
