CAUTION : Secondary operations may be performed on these gears except for modifications near or on the gear teeth.

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.
