Parallel Configuration
Acme Screw Drive
Acme screw actuators are used
for applications that require no
more than 50% duty cycle,
loads up to 1000 lb. at 0.4
inches per second or speeds
up to 8.5 inches per second at
10 lb. Acme screw units are
also a good choice for
applications that must not be
allowed to back drive. The
acme screw has enough friction
to hold the load in position with
power off or a motor stall
condition. The life expectancy
of an acme screw will be less
than that of a ball screw in a
particular application. Acme
screw units are also a lower
cost option than ball screw
units for similar load or speed
ratings. Acme screw units are
available in either in-line or
parallel configurations. In-line
versions are direct drive and
parallel versions are either belt
driven or gear driven.

For washdown applications
requiring a brake or encoder,
contact factory.)

Options
Mounting options: Rear clevis
Trunion
Side tapped holes
Mounting feet
Front flange
Rod ends: Tapped hole
Threaded rod
Spherical rod end
Encoders: Encoders are available mounted on either the
motor or the lead screw. The output of the
encoder is either 400 or 500 pulses per
revolution. The pulses per inch depends on
the gear ratio and lead of the screw. The 400
line encoder should be used with a full and
half-step control and the 500 line encoder
should be used with a micro-stepping control.

Actuator Accessories
Sensors
Sensor rating is 10W @ 120VAC or 200VDC. A N.O. (normally
open) sensor is provided with the actuator for home position.
Channels are manufactured on three sides of the cover tube to
accept additional sensors. The sensors are simply inserted in the
end of the channel and moved to the desired position. Set screws
secure the sensor in place. The leads from the sensor are then
wired to the I/O board supplied with the control. The SS2000
controls do not require diodes on the inputs and can accept either
N.O. or N.C. sensor inputs but not both.
Part Number
N.O. without diode 840-9005 (for use with SS2000 control)
N.C. without diode 840-9008 (for use with SS2000 control)
