corrosive environment with ambient temperatures
ranging from -20 to 200 ° F. If your environment is
dirty and/or contains abrasive particles it is impor-
tant to protect the screw with a boot. If your atmo-
sphere is corrosive it is important to specify a non-
corrosive material or finish. Duff-Norton can provide
stainless steel, nickel plated or epoxy coated actua-
tors. If your duty is high or your use severe, more
frequent lubrication should be employed. Duff-
Norton publishes a Mechanical Actuator Design
Guide, Catalog No. 2003, which you may find
helpful in the selection and application of mechani-
cal actuators. If you need additional help, please
