Actuator Components:
Drive types
Acme screw – economical choice for
lower load, speed and duty cycle
requirements. Acme screws are self-
locking by design and can not be back
driven by the load. They are
recommended for vertical applications or
other applications where back driving can
occur during loss of power. Acme screw
actuators have a 50% maximum duty
cycle rating.
Ball bearing screw – choice for higher
speed and load applications. Ball bearing
screws are highly efficient and consume
little power in converting rotary motion
into linear motion. Ball screw actuators
have a 100% duty cycle rating. Motor
power must be maintained to prevent
backdriving by the load.
Configurations
Parallel – this style of actuator allows the
broadest performance range with various
combinations of drive types and ratios,
screw types and leads, and motor sizes.
Speeds up to 15 inches per second at 20
lb. and loads up to 2000 lb. at 0.3 inches
per second define the performance limits.
A variety of mounting configurations are
available for parallel style actuators to
make installation as easy as possible.
In-line – direct drive with combinations
of motors, screws and leads provides
speeds up to 25 inches per second at 15
lb. and loads up to 1000 lb. at 0.2 inches
per second. In-line actuators are available
with front flange, trunion, side tapped
holes, or foot mounting to suit a variety of
applications.
Cover tube of anodized
extruded aluminum resists
corrosion, is lightweight and
allows positioning of sensors
along its length.
Stainless steel sxtension tube
protects against corrosion.
Rod end options
include a tapped hole,
threaded rod and
universal rod end.
Standard stroke lengths
available 2, 4, 6, 8, 12, 18, 24 inches
(for longer stroke lengths – consult factory)
Wiper and O-ring provide double
protection against dirt, dust and
water contamination.

Anti-rotation
feature prevents
the extension
tube from
rotating
Limit switches are
externally adjustable
along the length of
the cover tube and
can be mounted in
the T-slots on three
sides of the cover
tube.

Continuous Duty Cycle will handle the most
rigorous applications. (Ball screw version)
Life up to 50 million cycles depending upon
screw type and load
Resolution is less than 0.0005 inches
depending on the control selected.
Ambient temperature rating of -40 ° to
+150 ° F allows a wide range of applications.
Parallel or in-line versions for different
space requirements
Load ratings up to 2,000 lb. at .3 inches per
second continuous
Additional Features

at 15 lbs., variable up to the maximum speed.
A constant speed regardless of load up to
load/speed rating of the actuator
Programmable positioning available with
Superior Electric controls
Software package available that is menu
driven and units are expressed in linear terms
for easier and faster programming. No need
to learn special codes
Hazardous location versions are available.
