Note: 1. Multiply the value given above by the multiple strand factor (page A-22, Table II) in order to obtain the transmission horsepower of multiple strand chain. 2. For lubrication systems A, B & C, refer to page A-77 for explanation. Please consult U.S. Tsubaki for use of horsepower ratings to the right of the boundary line. 3. Refer to page A-22, “Procedures for Selecting Roller Chain.”
