CAUTION:	No secondary operations can be performed on these gears due to the carburizing process.
NOTE:	The allowable torques shown in the table are the calculated values according to JGMA Standards 401-01 and 402-01.The backlash values shown in the table are the theoretical values of a pair of identical gears in mesh. All dimensions shown in the above table(s) are listed in millimeters unless otherwise specified.
