Martin Sprocket & Gear — 527 Configurations
Overview
Specifications
Applications
Martin sprockets are precision-machined power transmission components designed for roller chain drive systems. Every tooth profile is cut to ANSI standards, ensuring smooth chain engagement, even load distribution, and maximum service life. Martin manufactures sprockets from high-carbon steel or ductile iron depending on the application, with hardened teeth available for high-load or abrasive environments.
Proper sprocket selection directly impacts chain life, drive efficiency, and maintenance intervals. Martin’s bore-to-size (BS) sprockets come with a finished bore, keyway, and setscrew — ready to mount out of the box. For applications requiring a specific bore size, Martin also offers sprockets with QD (Quick Detachable) or taper bushing mounts for fast installation and removal.
This product includes 527 variants (35BS9HT 3/8, 40BS9HT 1/2, 40BS9HT 5/8, 50BS9HT 5/8, 60BS9HT 3/4 and 522 more) covering common tooth counts and bore sizes for professional applications.
