Ratio Plates

When you need a ratio other than 1:1, Ratio Plates (Product Family Page) make it easy to position sprockets and pulleys at the perfect center-to-center distance for the given ratio and length of #25 chain or RT25 belt. Each ratio plate is designed for the indicated sprocket or pulley combination and a loop of chain or belt that is the indicated length. For example, 56PL equates to a 56 link loop of #25 chain or a 56 tooth RT25 belt.
