UltraTRUE True Planetary Gearheads

UltraTRUE True Planetary Gearheads

Micron® UltraTRUE™ planetary gearheads combine the attributes of helical-crowned gearings with TRUE Planetary™ orientation to create the smoothest, 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. In addition, Micron’s TRUE planetary gearing technology allows for highly efficient and precise torque multiplication for servo motor applications. Thomson Micron carries the UltraTRUE in many ratios stocked and available for immediate delivery.
