Nanotec Electronic (Germany) now offers new Nema 8 ( 20
mm flange size) and Nema 14 ( 35 mm) hybrid linear position-
ing drives. The motors are ideal for the design of compact lin-
ear axes as there is no need for the coupling and the bearing
support point for the screw. Features include:
Maintenance-free, thermoplastic nuts.
Forces of 40 N (Nema- 8) and 140 N (Nema- 14).
Step resolutions of 0.005 mm (Nema- 8) and
0.01 mm (Nema- 14).
Standard screw lengths of 75 or 150 mm.
The availability of high-resolution
( 2,000 incr/rev) encoders.
Integrated EtherCAT Interface
Dunkermotoren (Elgin, IL), now a unit of AMETEK Precision
Motion Control, has extended its range of compact brushless
DC servo motors with integrated intelligence and fieldbus con-
nectivity with 10 new models. The family now offers EtherCAT
interface on all of its BG45, BG65, BG65S and BG75 base mod-
els. Features include:
Availability in a range from 50 to 500 W of power and in
45 to 75 mm square frame sizes.
CANopen over EtherCAT (CoE) compatibility.
High-quality planetary and worm gearboxes.
Integral or connected absolute encoders.
Inline Electric Actuators
Warner Linear (Belvidere, IL) has announced the addition of the I-Track to its line of linear
actuators. The I-Track’s inline design was developed for light- and medium-duty applications
where parallel motor type actuators won’t fit in limited space requirements. Features include:
A release clutch that allows the actuator rod to float when power is off.
A load capacity up to 200 lbs.
Stroke lengths up to 12".
A ball screw for long life.
A steel rod for durability.
New SKF SYSTEM (Lansdale,
PA) 24 LAGD Series single-point
automatic lubricators are timely
and accurate solutions that deliver the proper pre-set amount of
lubricant needed for bearings
in machinery across industries.
These gas-driven feed versions
are engineered to perform reliably on a 24-hour basis without
manual intervention and can
resolve issues typically associated
with hard-to-access or potentially
hazardous lubrication points.
Flexible and user-adjustable
Transparent lubricant containers for visual inspection of
A patented gas cell that generates the proper pressure to dispense lubricant consistently.
Availability in 2 sizes
(60 and 125 ml).
Physik Instrumente (PI) (Auburn,
MA) has added a new hexapod to
its family of parallel positioning
devices. With a freely program-
mable center of rotation, these
devices are virtually as versatile as
the human hand. The new H-820
was developed for applications
that require multi-axis motion and
high flexibility, but do not need
precision on a nanometer or sub-
micrometer level. Features include:
Linear travel to 100 mm.
Rotary travel to 60°.
A load capacity of 20 kg.
A velocity of 20 mm/sec.
6 high-resolution actuators.
A randomized, user-program-mable pivot point.
An advanced motion controller
and a comprehensive software
ISO 9001 certification.
