Pitch Angle 45

CAUTION: A set of miter gears must be identical in module and number of teeth, but opposite in spiral hands.

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 items listed above as are available from stock until current inventory is exhausted. At that time the product will only be available on a made to order custom basis.

NOTE:
Due to heat treating, some deformation of the bore may occur. It may be necessary to ream the bore to bring it to the stated dimension.

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