Note: 1. When using one pitch offset links (OL), HP ratings are 80% of the above. Two pitch offset links (2POL) can be used at 100% of the above values. 2. Multiply the value given above by the multiple strand factor (page 251 Table 2) in order to obtain the transmission horsepower of multiple strand chain. 3. For lubrication systems A, B & C, refer to pages 257 & 258 for explanation. Please consult Tsubaki for use of horsepower ratings to the right of the boundary line. 4. Refer to page 251, “Procedures for Selecting Roller Chain.”
