Fixed displacement motors for open and closed circuits

Series 02 motors from Linde Hydraulics are different from those common in the market. They are able to provide the required torque even at low speeds and make it possible to start smoothly and sensitively. Therefore, additional gear ratios for rpm reduction are not necessary. This reduces the amout of parts going into the component and also increases the overall mechanical efficiency, minimizes windage losses as well as the noize level of the machine.

Advantages

  • steady low speed
  • high starting torque
  • compact design
  • high power density
  • high reliability
  • long service life

Design characteristics

  • axial piston motor in swashplate design for high pressure open and closed circuit systems
  • optimized starting and low speed behaviour
  • purge valves for circuit and case flushing optional
  • high pressure relief valves set fixed or variable optional
  • SAE high pressure ports radial or axial
  • SAE mounting flange with ANSI or SAE spline shaft
