*The numbers in the parentheses ( ) in the SFF-080 row at the top of the table are the values for when d1 is φ38mm.

*For the coupling on the flange side, please check the manufacturer specifications and mounting method for the other part before mounting it to the flange.

*We can also support mounting hole dimensions for the mounting pitch, size, and number other than those shown in the table, so please contact us if you have any questions.
