UltraTRUE True Planetary Gearheads

UltraTRUE True Planetary Gearheads

The UltraTRUE True Planetary® gearhead combines the positive attributes of Helical Crowned gearing with True Planetary orientation to create a smoothest and quietest gearheads on the market today. The internal gear is cut directly into the stainless steel housing to increase torque capacity and avoid slippage. The Helical cut of the gears provides higher torque capacity, precision and stiffness when compared to straight cut gears. Thomson Micron carries the UltraTRUE in many ratios stocked and available for immediate delivery though the Thomson Micron Gearhead Express program.
