About this part
What it is and why it is made that way
A gearbox housing is mostly volume and ribs, which is exactly what die casting is good at — it fills a complex cavity quickly and repeatably, at a unit cost that stays flat as the batch grows. The bearing seats and the mounting faces are machined afterwards, and they are what the gearbox is actually judged on.
- Complex cavity filled in a single shot, repeatable batch to batch
- Bearing seats and mounting faces machined after casting
- Ribs and bosses cast in, not welded on
- Leak tested and pressure tested options available
