Parker Gearheads

The Next Generation PS/PX/RS/RX Series Gearheads

Higher Radial Load, Increased Service Life, Universal Mounting Kits


The Next Generation Stealth Gen II Helical Planetary Gearheads provide superior performance with design enhancements allowing for higher radial load (four times greater in some cases) and increased service life (nearly double). Stealth Gen II incorporates more robust bearing support, dual angular contact bearings to support the output carrier, full compliment needle bearings to support the planet gears and optimized gearing geometries. Internal design changes allow for one fill level for any orientation, resulting in shortened part number designation and simplified order placement.

Key Features

  • Angular contact output bearings for higher radial load capacity
  • Full compliment needle planet bearings for increased service life
  • Universal mounting kits for quicker deliveries and easier mounting
  • Helical planetary gearing for high torque and low backlash
  • Integral ring gear and rigid sun gear for high stiffness
  • Plasma Nitriting for higher gear wear resistance
