08B1 23T Sprocket Comes With 28mm Bore & Keyway with 2 Grubscrews (4SR23 28BK&2GS)
The 08B1 23T Sprocket with 28mm Bore & Keyway is a precision-engineered power transmission component designed for reliable performance in high-capacity chain drive systems. This bored and keyed sprocket features a 23-tooth configuration with a 1/2" pitch, offering excellent torque delivery for heavy-duty industrial applications. It comes complete with dual grubscrews for secure shaft mounting, requiring no additional machining.
Key Features:
- 23 Teeth - Optimised for high-torque, lower-speed applications requiring maximum power transmission
- 1/2" Pitch (08B1) - Compatible with standard 1/2 inch pitch roller chains
- 28mm Pre-Machined Bore - Eliminates the need for additional machining and reduces installation time
- Integral Keyway - Ensures positive drive engagement and prevents shaft slippage
- 2 Grubscrews - Provides dual-point security for reliable and redundant shaft retention
Applications:
This high-tooth-count sprocket is ideal for use in:
- Heavy-duty conveyor systems and material handling equipment
- Industrial packaging machinery requiring consistent torque delivery
- Agricultural equipment and farm machinery
- General industrial power transmission systems with high load requirements
- Low-speed, high-torque chain drive applications
- Machine tool drives and manufacturing equipment
- Applications requiring compact, reliable power transmission
