These actuators are intended for a clean, non-corrosive
environment with ambient temperatures ranging from -20
to 200 ° F. If your environment is dirty and/or contains
abrasive particles it is important to protect the screw with
a boot. If your atmosphere is corrosive it is important to
specify a non-corrosive material or finish. Duff-Norton
can provide stainless steel, nickel plated or epoxy coated
actuators. 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 mechanical actuators. If you need
additional help, please contact Duff-Norton at (800) 477-
5002.
