Eaton Airflex Hydre-MAC Radial Piston Motors - Keeps Operations Up & Running

Industrial Clutch Parts Ltd. supply a complete range of Eaton Airflex Hydre-MAC Radial Piston Motors. Available in various sizes, suitable for applications in industries such as offshore, marine, metal recovery, mining, pulp & paper, fishing, winches, and off-highway.

Hydre-MAC Radial Piston Motors feature a low inertia design to provide instant stopping and reversing for highly dynamic applications. It's extremely smooth, low-speed operations enhance efficiency and lower operating costs. Superior mechanical efficiency further reduces energy consumption across 2000:1-speed ratio while delivering full torque to the machine shaft. 

Eaton's Hydre-MAC creates over 90% of stall torque efficiency to allow the operators to avoid over-sizing the motor and lowers overall maximum pressure requirements of the system. Cam lobes and pistons have been machined to allow internal forces on the main bearings to be balanced, freeing up the main bearings for external loads induced by mounting attitude and machine design.  Large bearings provide reliable and long life performance.


  • High efficiency lowers operating costs
  • Replaceable wear surfaces lower maintenance costs by extending maintenance intervals
  • Very low-pressure drop delivers more output torque
  • Symmetrical design reduces uneven loading to increase operating life
