What types of gears do you make?

We're a custom gear manufacturer producing spur, helical, bevel and mitre, and worm gears, plus sprockets, splines, racks and timing pulleys — all cut to your print. We also distribute and re-machine U.S. Tsubaki stock sprockets and chain.

How large a gear can you cut?

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.

Can you make a part if I don't have a drawing?

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.

What materials do you work with?

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.

How do you inspect quality?

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. Commercial Gear is a member company of the AGMA.

Do you handle prototype and low-volume work, or only production runs?

Both. We produce everything from a single prototype to a repeating production run on the same equipment. Tell us the quantity and we'll quote the job you actually have.

Can you troubleshoot a gear that keeps failing?

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.

How do I get a quote?

Send us your print, CAD file or a sample, along with the material, quantity and when you need it, and we'll price it. Use the quote form, email info@commercialgear.com, or for an urgent requirement call 800.491.1073.
