This
standard range of Precision Planetary Reducers are perfect for use in
applications that demand high performance, precise positioning and repeatability.
They were specifically developed for use with state-of-the-art servo
motor technology, providing tight integration of the motor to the unit.
Design features include mounting any servo motors (IEC,
NEMA, or customized motors), standard low backlash, high torsional
stiffness, 95 to 97% efficiency and quiet running.
They are available in
eight sizes with reduction ratios from 3:1 to 600:1 and output torque
capacities up to 7,376 lb.ft. The output can be provided with a solid shaft or ISO
9409-1 flange, for mounting to rotary or indexing tables,
pinion gears, pulleys or other drive elements without the need for a
coupling. For high precision
applications, backlash levels down to 1 arc-minute are available.
Right-angle and input shaft versions of these reducers are also available.
Typical
applications for these reducers include precision rotary axis drives,
traveling gantries & columns, material handling axis drives and electronic line shafting.
Industries served include Material Handling, Automation, Aerospace, Machine Tool and
Robotics.

Design & Construction |
Gearing:
Featuring HeliCamber® case-hardened & ground gearing with minimal
wear, low backlash and low noise, making them the most accurate and
efficient planetaries available. Standard planetary design has three planet gears, with
a higher
torque version using four planets also available, please see the chart below
under the "+" unit sizes.
Bearings:
Optional output bearing configurations for application specific
radial load, axial load and tilting moment reinforcement.
Oversized tapered roller bearings are standard for the ISO Flanged Reducers.
Housing:
Single piece steel housing with
integral ring gear provides greater concentricity and
eliminate speed fluctuations. The housing can be fitted with
a ventilation module to increase input speeds and lower operational
temperatures.
Output:
Available in a solid shaft with optional keyway or an ISO
9409-1 flanged
interface. We offer a wide range of standard pinions to
mount directly to the output style of your choice.

These reducers are typically selected based on the peak cycle forces, which
usually happen during accelerations and decelerations. These cycle
forces depend on the driven load, the speed vs. time profile for
the cycle, and any other external
forces acting on the axis.

information will be reviewed by our engineers, who will recommend the best
solution for your application.

 ISO
Flanged Pinions, are provided with ISO 9409-1 flanges
to mount directly
to our High-Torque (HT) Servo-Worm Reducers
and Precision Planetary Reducers. This interface provides a tight
integration of the pinion to the gearbox output, reducing overhung loading and
backlash between the components. The
pinions are easily mounted and replaceable if future repair is needed.
 Servo Reducers are available
in five levels of precision to meet any application needs. Perfect for use in applications that
demand high performance, precise positioning and repeatability.
Angular backlash levels down to less than 1 arc-minutes are
available as standard. Optional integral pinion shafts are
also available to mount directly to hollow output
shaft.
 Rack & Pinion Drives,
consisting of both helical & straight (spur) tooth
versions, in an assortment of sizes, materials and quality levels, to meet
almost any axis drive requirements.
