Parker Gear Heads - PS Series

The Stealth PS-series is Parker's highest performance inline servo gearhead, incorporating the latest technological enhancements. Helical planetary gears provide greater tooth contact and face width than spur gears, resulting in higher loads, smoother tooth engagement, quieter operation, and very low backlash. The use of an integral ring gear, cut directly into the gearhead housing, further increases torsional stiffness and allows PS-series gearheads to use larger gears and bearings, leading to greater torque output from a minimum package size. Dual angular contact bearings provide higher radial and axial load capacities while maintaining high input speeds. A full complement of needle bearings supports the planet gears, allowing for increased life and extended warranties.
