6DR11 Pilot Bore Chain Sprocket 12B2
The 6DR11 is a high-quality 12B2 British standard duplex roller chain sprocket manufactured by Medway. Designed with a pilot bore (or small bore hole) for versatile mounting options, this sprocket features 11 teeth and a 3/4 inch pitch, making it ideal for power transmission applications requiring compact duplex chain drive systems.
This sprocket is suitable for use with 12B2 duplex roller chains and is an excellent choice for applications where space is limited but increased torque transmission is required.
Duplex sprockets like the 6DR11 are engineered to handle higher 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.
