1-1. General

This manual contains maintenance instructions for
Duff-Norton
translating machine screw actuators of 2, 5
®
and 10-Ton capacity. It describes and details procedures
for installation, disassembly, cleaning, inspection, and
assembly of these actuators.

1-2 Applications

The actuators described and illustrated in this manual are
intended for industrial use only and should not be used to
lift, support or otherwise transport people unless you have
a written statement from Duff-Norton which authorizes
the specific actuator unit, as used in your application, as
suitable for moving people.

1-4. Important Precautions

In order to ensure that Duff-Norton actuators provide good
service over a period of years, the following precautions
should be taken:
1. Select an actuator that has a load rating greater than
the maximum load that may be imposed on it.
2. The structure on which the actuators are mounted

1-3. Specifications

These actuators are intended for a clean, non-corrosive
environment with ambient temperatures ranging from
0 to 200°F. If your duty is high or severe, more frequent
lubrication should be employed. If your environment
contains abrasive particles or a corrosive atmosphere,
Duff-Norton's Performance Line of mechanical actuators
may have a more appropriate solution for your application.
Duff-Norton publishes a Mechanical Actuator Design
Guide which you may find helpful in the selection and
application of mechanical actuators. A .pdf of the manual
can be downloaded from www.duffnorton.com. If you

should have ample strength to carry the maximum load,
and should be rigid enough to prevent undue deflection
or distortion of the actuator supporting members.
3. It is essential that the actuators be carefully aligned
during installation so that the lifting screws are
perfectly plumb and the connecting shafts are exactly in
line with the worm shafts. After the actuators, shafting,
