6DR13 Pilot Bore Chain Sprocket 12B2
The 6DR13 is a high-quality 12B2 British standard duplex roller chain sprocket manufactured by Medway. Designed with a pilot bore (or small bore hole) for flexible shaft fitting, this compact sprocket features 13 teeth and a 3/4 inch pitch, making it ideal for power transmission applications requiring reliable duplex chain systems with higher load capacity.
Duplex sprockets are engineered to handle higher loads and provide increased power transmission capacity compared to simplex alternatives, making them suitable for demanding industrial environments where durability and performance are essential. This smaller tooth count variant is particularly useful for applications requiring higher speed ratios and tighter spacing.
Key Specifications:
- Pitch: 3/4 inch (12B2 standard)
- Number of Teeth: 13
- Outside Diameter: 87.5mm
- Boss Diameter: 59mm
- Overall Length: 50mm
- Pilot Bore Size: 16mm
- Type: Duplex (double row)
