Spur Pinion Shafts
A pinion gear is the smallest gear in a gear drive, and/or the drive gear in a gear reducer. A pinion shaft is a pinion gear machined directly onto a shaft. Ondrives.US designs, engineers, and manufactures pinion shafts in a range of sizes, pitches, and teeth counts. We have the right pinion shaft for nearly any application. Order precision pinion shafts for your application, request a quote, or contact Ondrives.US for more information.
