NOTES

  1. Horsepower, torque, output speed and overhung load capacities based on 1750 rpm input speed and 1.00 Service Factor.

  2. Non-standard ratios available.  Consult Dorris Company if desired ratio is not shown.

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

  4. Overhung load is measured at the midpoint of the key for the input and output shafts respectively.

  5. Measured at the input shaft.

  6. If a backstop is required consult Dorris Company for backstop torque capacity as it is less than the output torque rating shown.

  7. Consult Dorris Company for thermal capacity in your application.
