Both. We produce everything from a single prototype to a repeating production run on the same equipment. Tell us the quantity you need and we’ll quote the job accordingly.
What we make to order and what we supply from stock.
We’re a custom gear manufacturer producing spur, helical, bevel and miter, and worm gears, plus sprockets, splines, racks and timing pulleys, all cut to your print. See the full range on our Products page.
Yes. We distribute U.S. Tsubaki stock sprockets and chain, and we can re-machine stock sprockets to suit your application. See Stock Sprockets & Chains.
Cutting capacity, materials and working from samples.
Our cutting capacity is hobbing from 1/4″ to 60″, shaping from 1/8″ to 36″ diameter, and bevel gearing from 1/4″ to 24″ diameter. If your part is near those limits, send the print and we’ll confirm the fit.
We cut gears to your print across a wide range of materials, and we offer many sources for heat treating and metal finishes. Tell us the material and specification on your drawing and we’ll confirm it.
Often, yes. We reverse-engineer parts from a sample regularly. Send us the worn or broken part and we’ll work back to the correct tooth form and dimensions. A clear sketch with the mating dimensions can also be enough to get started.

How every part is inspected and verified against your drawing.
Our Quality Control Department bases its inspection on the AGMA Inspection Manual 2000-A88. We measure profile, lead and composite error on calibrated ITW, Fellows, Gleason and Brown & Sharpe instruments, verifying the tooth form against your drawing. Read more in our Quality Policy.
Yes. Commercial Gear & Sprocket is a member company of the AGMA (American Gear Manufacturers Association), and our inspection is based on the AGMA Inspection Manual 2000-A88.
Troubleshooting, replacement parts and reaching our team.
Yes. Troubleshooting difficult gear problems is part of what we do, including parts made elsewhere. With over 120 years of combined industry experience, our people can evaluate the data and offer a corrective plan of action rather than just cutting another one.
Yes. Send us the drawing, or the worn or broken part itself, and we’ll reverse-engineer it to the correct tooth form and dimensions, whoever made the original.
