NOTES

Horsepower, torque, output speed and overhung load capacities based on 1750 rpm input speed and 1.00 Service Factor.
Non-standard ratios available. Consult Dorris Company if desired ratio is not shown.
Overhung load is measured at the midpoint of the key for the input and output shafts respectively.
Measured at the input shaft.
If a backstop is required consult Dorris Company for backstop torque capacity as it is less than the output torque rating shown.
Consult Dorris Company for thermal capacity in your application.
