This 1Pcs 04C chain gear is designed for industrial sprocket wheels and motor chain drive sprockets. It is manufactured from 45# steel for strength and durability. The gear features an adjustable bore from 6 mm to 16 mm, enabling straightforward mounting on common shafts. It has 1023 teeth, providing flexibility for different gear ratios within the 04C chain family. The size is 10 mm and the color is listed as 13 Teeth. Key attributes Model/type: 04C chain gear Teeth: 1023 teeth Bore: 6 mm to 16 mm Size: 10 mm Material: 45# steel Applications: industrial sprocket wheel, motor chain drive sprocket Quantity: 1 piece Color: 13 Teeth Benefits and suitability Versatile bore design supports multiple shaft diameters without custom machining, reducing setup time. Robust 45# steel construction provides reliable performance in industrial environments. Wide tooth range (1023) offers flexibility to achieve desired gear ratios with standard 04C chain drives. Compact 10 mm size makes it suitable for small to midsize drive systems. Use cases Replacing a worn or damaged sprocket on a motordriven conveyor or small production line that utilizes 04C chain drives. Upgrading a CNC router, robotic arm, or hobbyist machine that runs on an 04C chain system, where bore compatibility is needed between 6 mm and 16 mm. Serving as a spare or upgrade part for maintenance kits in industrial machinery that uses chaindriven sprockets with variable bore requirements. Notes Ensure proper alignment and mounting tolerance when installing to maintain chain tension and system efficiency. Verify compatibility with the target 04C chain pitch and the shaft bore to select the correct combination of teeth and bore range.
