Direct motor mounting on worm gear screw jacks is
done with IEC flange and flexible
couplings, provided the weight and dimensions of the two drive
elements do not differ too much.

Encoders are used to synchronize,
position, or vary the speed of an electric motor.

Pillow Blocks are designed to operate with actuators
, shafts, and couplings. Pillow Blocks may be
used in any shafting configuration for additional shaft support.

SMB swivel mounting base enable
Pfaff screw jacks to be swiveled and tilted.
For this purpose,
the drive elements are movably mounted at two points.

Flange Blocks lock on to the end of the rotating screw, and
can then be bolted on to the machine or
fixture. This ensures that the load being carried by the actuator’s
lifting nut is properly guided.

The hand wheel is for actuators that require
precise positioning, or have loads
which do not require motorized power to adjust.

The Position Feedback Potentiometer/Transducer is
designed to mount on the end of any SKA6000T
limit switch. Its active component is a precision
potentiometer which may be used as voltage

The use of a bellows boot for is highly recommended
most actuator applications. Duff-Norton can
provide bellows boots for the most stringent application requirement.

Duff-Norton can competitively supply motors for
any application from suppliers such as Baldor,
Nord, US Electric, Leeson, and more.
Motors can be directly mounted to most Duff-Norton actuators using C-face adapters, directly mounted via speed reducers, or remotely mounted with shafting and couplings. IEC, servo, hydraulic, and air motors can also be supplied upon request.

Motor adaptors allow direct coupling of
motor shaft with either the left or right side
actuator input shaft.

The Digital Position Indicator processes a feedback signal
from the potentiometer to provide
position readout. The indicator automatically scales the input
signal to provide linear readout over the full travel length.

Power transmission systems frequently use
multiple actuator arrangements. Such systems
commonly use mitre boxes to effectively position and
equally distribute loads.

Duff-Norton provides three coupling types
which have been tailored to specific actuator
requirements: Chain, Jaw, and Flex Rigid.

Torsionally flexible couplings of the R series dampen vibrations and
shocks and compensate for axial, radial and angular misalignments. They are
therefore preferable to rigid couplings or
shaft connections.
