Rack Gears Made to Your Print
Tracey Gear & Precision Shaft manufactures straight spur rack gears to customer blueprints, up to 72″ long and 3″ face width, from 3 to 48 diametral pitch. Every rack is made in our Pawtucket, Rhode Island facility under an ISO 9001:2015 certified quality system, in small to medium production runs, 100% in the USA.
We are a build-to-print shop. You supply a complete engineering drawing, and we develop the manufacturing method to hold the gear data, tolerances, and finishes it calls out.
