CAUTION: Dimensions of the outside diameter, the overall length and crown to back length are all theoretical values, and some differences will occur due to the corner chamfering of the gear tips.

NOTE:
The allowable torques shown in the table are calculated according to JGMA Standards 403-01 and 404-01.

USEFUL HINT :
Black oxide coating is a film of Triferotetraoxide (Fe₃O₄), a kind of rust, which is applied to the gear surface to help resist rusting.
