Overview
The Browning HN100B11 11 tooth sprocket is a single-strand idler sprocket engineered for #100 roller chain systems. Manufactured with hardened steel teeth and precision needle bearings, this sprocket delivers reliable tension take-up in conveyor drive, power transmission, and chain tightening applications. The HN100B11 replaces worn idlers and maintains consistent chain engagement across industrial equipment.
Key Features
- 11 teeth optimized for #100 ANSI chain pitch (1-1/4″)
