Gates Belts, Hoses, and Applications: Not All Sprockets Have Flanges

Did you know that not all sprockets have flanges? In belt drive systems Gates typically only recommends the smaller sprocket to have flanges on both sides. This is to account for any belt tracking issues that may occur if alignment between the sprockets is slightly off. When misalignment becomes worse, the belt tends to track in one direction rather than remain neutral on the sprocket.
