AE120 Precision Planetary Gearbox — Product Overview

The AE120 is an inline precision planetary gearbox delivering output torque of 200 Nm with backlash as low as ≤3 arcmin. It is engineered as a direct mechanical replacement for the APEX AE120, sharing identical flange dimensions, bolt patterns, and shaft interfaces for a zero-rework retrofit. Each unit ships factory-tested under full load, with backlash, vibration, and noise readings recorded on an individual QC certificate.

Manufactured under an ISO 9001-certified quality system, this planetary gearbox is increasingly specified across Australia’s automation, packaging, and machine-tool sectors. Contact us for a same-day engineering recommendation and quotation.

Key Components Inside the AE120 Planetary Gearbox

Understanding the internal architecture helps engineers evaluate gear mesh quality and predict maintenance intervals. Below is a breakdown of the six core parts inside the AE120.

Sun Gear

Case-hardened 20CrMnTi steel sun gear with helical tooth profile, ground to Ra 0.4 µm. Connects to the servo motor input shaft and distributes torque to the surrounding planet gears with minimal friction and noise.

Planet Gears

Three equally-spaced planet gears orbit the sun gear while meshing with the ring gear. Multi-point load sharing delivers higher torque density and longer service life than single-mesh arrangements.

🔄Planet Carrier

Forged alloy steel carrier holds the planet gears in equidistant positions and converts their orbital motion into a single rotary output. Withstands repeated shock loads without deformation.

Ring Gear

Nitrided 42CrMo steel ring gear interference-fitted inside the aluminium housing. Maintains consistent backlash over the full rated service life.

🔗Bearings & Shafts

Tapered roller output bearings handle combined radial/axial loads; deep-groove ball input bearings support high-speed rotation. Preload set during assembly for optimal stiffness.

🛡Housing & Seals

CNC-machined aluminium alloy housing with double-lip FKM seals at both flanges. IP65 protection keeps lubricant in and contaminants out.

Industry Applications for the AE120 Gearbox

Robotics and Motion Control

In robotic joints and end-effector axes, the AE120 provides the torsional rigidity needed for path fidelity during high-acceleration moves. Its compact inline form reduces arm inertia, allowing faster cycle times.

Automation and Packaging Lines

The AE120’s wide ratio range lets packaging engineers size the planetary gearbox for automation without extra belt-and-pulley stages. IP65 sealing ensures reliable operation in cold-chain and ambient environments alike.

CNC Machine Tools and Medical Equipment

Ball-screw feeds, grinding-spindle drives, and surgical-robot actuators share a need for vibration-free torque. The AE120’s low-noise helical mesh and tight backlash meet these demanding standards. Precision planetary gearbox custom modifications available on request.

Performance Advantages of the AE120

Ultra-Low Backlash

The AE120 ships with backlash from ≤3 arcmin (micro) to ≤7 arcmin (standard), letting engineers match precision to cost. Multi-axis servo systems maintain repeatability over the full ≥ 20,000 hours service life.

High Torque Density

Output torque of 200 Nm in a compact housing makes the AE120 ideal for space-constrained builds — cobot joints, semiconductor handlers, compact conveyors.

Efficiency >95%

Each stage operates at >95% efficiency, compounding into measurable energy savings versus worm gear reducer alternatives that lose 30–50 % of input power as heat.

Manufacturing Process for the AE120

Every AE120 follows a controlled six-step production sequence.

1Application Review

Engineer reviews your servo specs, load profile, and duty cycle to recommend optimal configuration.

2Gear Cutting & Grinding

Gears hobbed on CNC centres, profile-ground to AGMA Class 11+, surface finish below Ra 0.4 µm.

3Heat Treatment

Carburising and quenching to 58–62 HRC tooth-surface hardness with tough core.

4Precision Assembly

Cleanroom assembly with backlash measured and adjusted to ordered grade.

5Full-Load Testing

Run at rated torque/speed; vibration, noise, backlash recorded on individual QC certificate.

6Packaging & Dispatch

Anti-corrosion coating, vacuum-sealed, palletised to Condell Park NSW warehouse.

What Our Customers Say

DM
David M.
Automation Engineer, Sydney NSW
★★★★★

“We fitted EP-series gearboxes on a 12-axis pick-and-place cell. Backlash measured tighter than the spec sheet promised. After 14 months and roughly 8,000 hours, no measurable increase. The cost saving let us stock spares on-site.”

KT
Karen T.
Maintenance Manager, Melbourne VIC
★★★★★

“Our packaging line runs 20 hours a day. The EP gearbox has been running over a year with zero unplanned stoppages. Being able to order individual seal kits instead of scrapping the whole unit is a big plus.”

RP
Raj P.
CNC Workshop Owner, Brisbane QLD
★★★★☆

“Positioning accuracy within ±0.01 mm on a CNC lathe turret drive. Delivery from Condell Park took four days to Brisbane — faster than importing from Europe.”
