6DR17 Pilot Bore Chain Sprocket 12B2
The 6DR17 is a high-quality 12B2 British standard duplex roller chain sprocket manufactured by Medway. Designed with a pilot bore for versatile mounting options, this sprocket features 17 teeth and a 3/4 inch pitch, making it ideal for power transmission applications requiring increased load capacity and torque transmission.
This sprocket is suitable for use with 12B2 duplex roller chains and is an excellent choice for applications where higher power transmission is required. Duplex sprockets like the 6DR17 are engineered to handle greater loads and provide increased power transmission capacity compared to simplex alternatives, thanks to their dual-row design. The pilot bore allows for custom machining to achieve precise shaft fitting or the addition of a taper lock bush for secure mounting.
