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
