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.
Double reduction high speed shaft dimensions shown in parentheses ( ).
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.
