Convenient, printable .PDF file

This printable reference chart will help you identify and reverse engineer your unknown gears and gear racks. The PDF has true-to-scale templates for Diametral Pitch 8-48 and Module 0.40-3.00 in both 14.5º and 20º pressure angles, the most common for all modern gears.

Works with Diametral Pitch and Module gears

The reference chart is fully compatible with both Diametral Pitch and Module gears. Whether your gear was designed with metric (Module) or imperial (Diametral Pitch) units, the templates will align with all the common measures. Simply line your gear up to the template and find the best match!

Reference equations, links, and more

The reference sheet includes the most common equation for reverse engineering a gear, as well as links (QR Codes) to our guides both in YouTube video and blog post to help you through the process. We also supply over 1000 gear cutters to help you make a replacement gear for what you've just identified. Just a note, the preview image is not-to-scale, but the PDF download certainly is!
