Need a durable sprocket for a chain drive system? This TRITAN B-Hub sprocket is built tough. It's an ANSI #60 size, which means it's made for 3/4-inch pitch roller chain. It has 13 teeth and a 1-inch finished bore (the hole in the center), so it'll fit a 1-inch shaft. The 'B-Hub' means it has a built-in hub on one side for extra strength. It's made from high-quality carbon steel and has a black oxide finish that helps resist rust. It comes with a keyway and TWO set screws – one over the keyway and another 90 degrees around – to really lock it onto your shaft and prevent slipping. This is a industrial-grade component, perfect for machinery, conveyors, agricultural equipment, or any project where you need a reliable power transmission link. The heat treatment adds to its durability. If you're replacing a worn sprocket or building a system from scratch and need the #60 size with these specs, this is a solid, professionally-made option.
