Pitch Angle 60
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 :

The shafts of miter gears are at 90 Miter gears with other angles are called angular miter gears. SAM series of KHK standard angular miter gears are available with 45,60 and 120 shaft angles.
