Overview
Pearson Manufacturing provides access to precision gear cutting, shaping, hobbing, and grinding — delivering AGMA-quality gears that meet demanding fit and finish requirements. We support prototypes and production through a hybrid model: some work is done at our Ontario facility, while specialized or high-capacity gear work is fulfilled via certified Canadian partners under Pearson QA.
⚠️ Hybrid fulfillment: We route in-house or via partner based on envelope, quality, and schedule — all under a single PO.
Quick Specs
| Process | Best For | Throughput | Notes |
|---|---|---|---|
| Hobbing | Most spur/helical, medium–high volume | Very High | Cost-effective; consistent lead time |
| Shaping | Internal gears & splines | High | Great for internal profiles/keyways |
| Broaching | Internal splines/keyways (repeat work) | Very High | Fast cycle; requires broach tooling |
| Gear Grinding | High precision & finish | Medium | Tight AGMA after heat treat; low runout |
| 5-Axis Milling (review) | Prototypes & specials | Medium | Flexible routing for unique geometry |
Capabilities We Provide Access To
- Spur, helical, bevel, worm gear machining (internal & external)
- Internal/external involute splines (and straight-sided), keyseating & hub features
- Blank turning/milling, hub/bore machining, keyways prior to tooth cutting
- Hobbing, shaping, broaching; profile & face grinding for precision finish
- Tooth chamfering/deburring, run-in, and lapping per specification
- Heat treatment coordination (carburize, nitride, induction) and post-grind sizing
- Dimensional, involute, lead & runout inspection — FAIR/FAI and reports on request
Design for Manufacturability (DFM)
- Provide complete tooth data: tooth count, module/DP, pressure angle, helix angle, face width, center distance (if known).
- Call out AGMA quality only as required — tighter classes increase cycle time and cost.
- If heat treat is required, specify method (carburize/nitride/induction) and case/core targets; allow post-grind stock.
- Define backlash or fit (e.g., class of fit for splines) and any match-gear or master-gear requirements.
- Add chamfers/deburr notes for tooth edges; specify cosmetic faces and marking locations.
- When reverse-engineering, supply OD, face width, bore/keyway, approximate module/DP, photos with scale, and mating parts if available.
We’ll review your drawing/CAD and confirm achievable specs and routing (in-house or partner) before kickoff.

Gear Machining FAQs
What information do you need to quote a gear quickly?
Upload STEP/IGES + PDF with tooth count, module/DP, pressure angle, helix angle (if any), face width, bore/hub details, keyway/spline data, material, quantities, and any AGMA quality + heat-treat spec.
Do you cut both internal and external gears?
Yes — internal/external spur and helical, plus internal/external splines. We choose shaping, broaching, hobbing, or milling based on geometry and volume.
Can you meet AGMA gear tolerances?
AGMA 8–12 is commonly achievable depending on size, material, and process (e.g., grind after heat treat). We’ll align routing to your quality requirement.
Do you provide heat treatment or coatings?
Yes. We coordinate carburizing, nitriding, induction hardening, black oxide, phosphate, and passivation. When required, we finish-grind teeth after heat treat for final size & finish.
Can you reverse-engineer a gear if I only have a sample?
Often yes. Share photos with a ruler for scale and basic measurements (OD, face width, bore/keyway). We can measure tooth data and produce drawings for approval.
Is the work done in-house or through partners?
Both. We machine blanks and some gears internally; specialized or high-capacity gear work runs through certified Canadian partners — all under Pearson QA and a single PO.
