Machined from steel, it features 17 teeth on a 5\/8 inch pitch, a finished bore diameter of 1-1\/4 inches, and an outside diameter of 3.72 inches. The hub diameter measures 2.703 inches. This sprocket ships ready to mount on a 1-1\/4 inch shaft without additional machining, making it a direct drop-in component for conveyor drives, industrial equipment, and mechanical power transmission assemblies. Installation is typically performed by millwrights, maintenance technicians, or mechanical contractors.\u003c\/p\u003e\u003cp\u003eThis sprocket is suited for light-to-medium duty industrial drive systems that use ANSI No. 50 roller chain. Common applications include conveyor systems, packaging equipment, agricultural machinery, and general industrial drive trains where a 5\/8 inch pitch chain and a 17-tooth count are specified. The finished bore design eliminates the need for on-site boring, making it practical for direct shaft mounting in field service or maintenance scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e17-tooth count on 5\/8 inch pitch for use with ANSI No. 50 roller chain\u003c\/li\u003e\n\u003cli\u003eFinished bore at 1-1\/4 inches — mounts directly to shaft without additional machining\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in industrial drive environments\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 3.72 inches and hub diameter of 2.703 inches for precise fitment\u003c\/li\u003e\n\u003cli\u003eMinimum and maximum bore diameter are both 1-1\/4 inches — no boring range, exact fit only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ANSI No. 50 roller chain at 5\/8 inch pitch.
