#40 BTB sprockets are designed for #40 roller chains with a 1/2-inch pitch. Featuring a BTB hub (Bushings Taper Bushed), they utilize a tapered bore that accepts a tapered bushing. The bushing is tightened onto the shaft, establishing a secure connection between the sprocket and the shaft. This design streamlines installation and ensures reliable power transmission in industrial applications.
