Hypoid Gears
Hypoid gear sets for offset right-angle drives, lapped and quiet under load.
Hypoid sets where the pinion axis is offset from the wheel, which lets a bigger pinion carry more load in the same space. They run on a sliding contact, so the oil matters as much as the geometry.

What drives the price of this part
Derived from the callouts on this page. Where a driver is not on the drawing, it is not on this list.
- Part size
- Module range at 2–10 module decides which machine the part lands on and how many setups it needs. Size is the driver buyers most often leave out of a first enquiry, and it is the one that changes the quote fastest.
- Material
- The first material listed, Carbon Steel 8620 (case hardening), rates 7/10 on our machinability scale at 149–200 HB (as-supplied) · 58–62 HRC case after carburising. On this shop's scale a harder alloy means slower passes and more tool changes, and that is cycle time the quote has to carry.
- Order size
- Minimum order is 5 pieces, so on a first order setup and programming are spread over very few parts and they are most of the price. Repeat orders at the same quantity are cheaper without anything on the drawing changing.
See how cycle time is calculated in the machining time calculator and what else moves a price in the cost driver reference.
How these parts are inspected
Matched to the callouts above and the instruments actually on the floor.
- Coordinate measuring machine (Zeiss CONTURA G2, two machines, GR&R 8.4% on the critical feature)
- Dimensional report against the drawing, with a 100% check on critical features rather than a sample
- Certificate of conformance and the mill certificate with every shipment
- First article inspection to AS9102, because this family carries an aerospace or automotive certificate
The full equipment list, with counts, is on the capability page; the inspection sequence is on quality and inspection.
Questions buyers ask
- Why does a hypoid drive need a special oil?
- Because the teeth slide as well as roll, which puts extreme pressure on the film. A standard gear oil breaks down and the flanks scuff - that is what the EP additive is for.
