UltraTRUE™ Thomson Micron Planetary GearboxUltraTRUE™ Thomson Micron Planetary Gearbox

Thomson Micron's UltraTRUE™ Planetary Gearbox combines the benefits of Helical Crowned gearing and True Planetary orientation, making it one of the smoothest and quietest gearheads on the market.

To increase the torque capacity and to avoid any slippage the internal gear is cut directly into the stainless steel housing. This Helical cut offers higher torque capacity, precision and stiffness when compared to straight cut gears. The Thomson UltraTRUE comes in many ratios and is available for immediate delivery though the Thomson Micron Gearhead Express program.


Thomson Micron's UltraTRUE™ Planetary Gearhead features include:

  • Tapered roller bearings
  • Helical crowned HRC 55-60 steel gears
  • Sealed deep groove ball bearing
  • RediMount™ system providing error-free motor installation
  • Single piece output integrated output housing and internal gear
  • Anodized aluminum housing reducing weight and prevents corrosion
