NOTE 1: Due to the thin face width, if you wish to perform secondary operations on these gears, please use care to avoid side run out and deformation. If you heat treat them, there is the possibility of warping these gears.NOTE 2: The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see page 27 for more details.
