What Is the MD110 Planetary Gear Reducer?
Designed as a bolt-for-bolt alternative to the APEX MD110, this inline precision planetary gearbox pairs helical-ground planet gears with a case-hardened sun gear to deliver 1300 Nm output torque. All mounting interfaces replicate the original APEX dimensions, enabling a direct swap with zero mechanical rework. Backlash grades span from <3 arcmin (micro) through <8 arcmin (standard), and transmission efficiency reaches >98%.
Every gearbox leaves the factory with an individual QC certificate. Our gear reducer engineering team provides free application sizing and 3-D CAD models from our Condell Park NSW office.
Where the MD110 Planetary Gearbox Fits
CNC and Machine-Tool Feed Drives
Ball-screw axes on lathes and milling centres require the torsional rigidity that the MD110 delivers in a compact inline envelope, keeping machine footprint tight while handling combined cutting forces.
Packaging, Printing and Textile Machinery
With output torque of 1300 Nm and efficiency of >98%, the MD110 cuts energy consumption versus worm gear alternatives while maintaining positional synchronisation across multi-axis servo lines.
Collaborative Robotics and Semiconductor Handling
Lightweight cobot joints and wafer-transfer stages prize minimal backlash (<3 arcmin) and low noise (≤ 65 dB(A)). Contact us for custom output shaft options.
Key Components Inside the MD110 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 MD110.
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.
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.
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.
Nitrided 42CrMo steel ring gear interference-fitted inside the aluminium housing. Maintains consistent backlash over the full rated service life.
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.
CNC-machined aluminium alloy housing with double-lip FKM seals at both flanges. IP65 protection keeps lubricant in and contaminants out.
Why Engineers Specify the MD110 Gear Reducer
Backlash Control
Backlash grades from <3 arcmin to <8 arcmin give engineers flexibility. CNC feeds typically use the reduced grade; optical positioning and semiconductor handling benefit from micro.
Load Capacity and Rigidity
Three simultaneous gear meshes yield higher torque density than single-mesh arrangements. Torsional rigidity of ≥ 7 N·m/arcmin keeps angular deflection under control during rapid accel/decel cycles.
Energy Efficiency
Rated at >98%, the MD110 converts nearly all input power into output torque. Lower heat generation extends lubricant life and bearing intervals, reducing total cost of ownership.
