Ball screw actuators are used in
applications that require duty
cycles up to 100%, high load or
high speed capability. Electrically
released brakes can be used to
prevent back-driving of the screw
with power off. Ball 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. Flange,
clevis, foot, and side tapped
holes provide versatile actuator
mounting and the three rod end
options provide either a very rigid
connection for precise
applications or a compliant
connection for applications that
require multiple degrees of
freedom.

Mounting options: Rear clevis
Trunion
Side tapped holes
Mounting feet
Front flange
Rod ends: Tapped hole
Threaded rod
Spherical rod end
Brake: Load holding brakes are available mounted on
the motor to prevent back driving the load with
the power off. The brake is spring set and
electrically released to prevent load movement
during power off conditions.
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 inputs and can accept either
N.O. or N.C. sensor inputs but not both.
Part Number
