Sprockets Made to Your Print
Tracey Gear & Precision Shaft manufactures roller chain, silent chain, and ladder chain sprockets to customer blueprints, in single, double, and multiple strand, up to 36″ in diameter for 1/2″ to 2″ chain pitch. Every sprocket 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 tooth form, tolerances, and finishes it calls out.
