Gears We Manufacture
We cut gears for automotive powertrains, aerospace systems, industrial machinery, robotics, and medical devices. Every gear is custom-designed for your load and speed requirements.
Spur Gears
Straight-tooth design, highest efficiency, most common type. All module sizes.
Helical Gears
Angled teeth, smooth operation, lower noise. Better load distribution than spur.
Bevel Gears
Angled-shaft drive. Straight-tooth, spiral, and Zerol designs available.
Worm Gears
High-reduction right-angle drive. Self-locking capability for some designs.
Rack and Pinion Sets
Rotary-to-linear motion. Precision-ground racks with matching pinions.
Internal Gears
Ring gears for epicyclic or compound gearboxes. High torque density.
Cluster Gears
Multiple gears on one hub. Common in gearbox designs.
Custom Gear Profiles
Non-standard module, pressure angle, or tooth geometry. Design support included.
Materials Available for Gears
Gear materials are selected for strength, fatigue resistance, and wear characteristics.

Gear Machining FAQ
What gear types can you manufacture?
We manufacture spur gears (straight teeth, high efficiency), helical gears (angled teeth, smooth operation), bevel gears (angled shafts), worm gears (right-angle drive), and custom profiles. Rack and pinion sets and internal gears are also available. Gear cutting is performed on precision gear-cutting machines with hob and shaper capabilities.
What materials are best for high-load gears?
Steel 4140 and 4340 are standard for high-load applications — they provide maximum strength and fatigue resistance. Stainless steel 17-4 PH is used where corrosion resistance is required. Bronze and brass are preferred for low-friction, self-lubricating applications. Material choice depends on load, speed, and lubrication method.
What tolerances can you hold on gear teeth?
We cut gears to AGMA 10 and 11 tolerances (commercial and high-precision grades). Involute profiles are held to ±0.02mm. Tooth spacing is held to ±0.01mm on the bolt circle. Runout is controlled to ±0.01mm TIR for precision applications.
Can you manufacture gears to AGMA or DIN standards?
Yes. We design and cut gears to AGMA 2005 and 2101 standards and DIN 3962. Our gear design software verifies contact patterns, load capacity, and interference before cutting. Gears are cut with precision cutting tools and inspected with CMM measurement.
What is the typical lead time for custom gears?
Simple spur gears typically ship within 10–15 business days. Complex helical or bevel gears may require 15–25 business days. Lead time includes design review, cutting, heat treatment (if required), and final inspection. Lead time is confirmed in your formal quote.
Do you offer gear cutting for prototypes?
Yes. Prototype gears are cut and inspected the same way as production gears. Single-off gears are often more cost-effective than smaller production runs because setup time is spread across the part. We recommend prototype testing to verify performance before production commits.
