28B1-35 Pilot Bore Sprocket
28B1-35 Simplex Chain Sprocket
This 28B1-35 pilot bore sprocket is a British standard roller chain sprocket engineered for reliable power transmission in industrial machinery applications. With 35 teeth and a 1.3/4 inch pitch, this sprocket delivers smooth engagement and consistent performance in demanding systems, making it ideal for high-torque, lower-speed applications.
Key Specifications:
- 28B1 British standard roller chain sprocket
- 1.3/4 inch pitch x 35 teeth
- Outside diameter: 514mm
- Boss diameter: 180mm
- Pilot bore size: 30mm
- Overall length: 75mm
- Manufactured by Medway to exacting standards
Design Features:
The pilot bore design allows for precise machining to your exact shaft requirements, making this sprocket ideal for custom installations and replacement applications. This feature eliminates the need for additional modifications and ensures a perfect fit for your specific power transmission system. The 35-tooth configuration provides maximum torque multiplication, making it suitable for applications requiring lower output speeds with increased power delivery.
Applications:
This 35-tooth configuration is ideal for heavy-duty industrial applications including conveyor systems, manufacturing equipment, packaging machinery, and demanding industrial drives where reliable chain transmission and high torque characteristics are essential. The larger tooth count makes it particularly suitable for applications requiring slower speeds with increased torque output.
