Allen-Bradley 25B22-1/2 Roller Chain Sprocket

Description:

The Unkeyed Sprocket 25B22-1/2 is a single-strand roller chain sprocket designed to transmit rotary motion and power in industrial chain drive systems. Commonly installed in conveyors, packaging machinery, agricultural equipment, food processing systems, and material handling equipment requiring a #25 chain sprocket with 22 teeth and a 1/2 in. finished bore. Maintenance teams and system integrators use this sprocket for replacement of worn drive components, equipment repairs, and restoration of efficient power transmission. 

Applications:

The Unkeyed Sprocket 25B22-1/2 is commonly used in industrial automation, conveyor systems, packaging equipment, robotics, and light-duty power transmission applications where precise chain engagement and reliable torque transfer are required. Its steel construction provides durability and long service life in continuous-duty industrial environments.
