Hydre-MAC Radial Piston Motor

Eaton’s Hydre-MAC™ is a low-speed, high torque (LSHT) direct drive, radial piston motor – featuring a cam lobe design – for variable speed applications that use less energy to deliver more power when needed. The Hydre-MAC radial piston motor can deliver 900kW of power and up to 280,000Nm of torque at max pressures of up to 350 bar all while delivering over 94% efficiency. With a symmetrical, 18-piston/roller assembly design that eliminates side loading, and two inlet/outlet ports that reduce pressure drop at high power, the Hydre-MAC radial piston motor generates less heat and experiences less wear and tear.

Features

  • Eight cam lobes provide 144 power strokes per revolution, delivering class-leading, low-speed performance
  • Symmetrical design with 18-piston/roller assemblies ensures even loading of all components to reduce wear
  • Flame-hardened cam delivers long-lasting motor reliability
  • Load bearing surfaces on the Hydre-MAC radial piston motor are serviceable, including the stainless steel shaft seal wear ring, piston seal and bearing pad
  • Based on the same principals as the partially discontinued Hagglunds Marathon Motor and developed in partnership with MacTaggart Scott, the Hydre-MAC motor is direct, drop in replacement for the Marathon motor.  It uses the same shaft and mounting hardware, making switching costs a non-issue during replacement
