Hydraulic Helical Gears Rotary Actuator

ECKART E3 Series (210 bar)

  • For the mobile application.
  • Torque: 3600 Nm max at 210 bar.
  • Angle of rotation: 180° or 360° (others on request).
  • With valve block (option)
    • Loading hold function.
    • Clamp function.
    • Overpressure function.
  • Maximum operating pressure: 210 bar.

Your advantages at one view:

  • Ultra compact, robust construction
  • Exact, almost free from backlash positioning
  • No leakage in the inside, in case of that double shaft and piston sealing (lip seal)
  • Hydraulic seals concerning the newest stand of technic
  • Any intermediate angle possible
  • High bearing charge
  • One or both way attachment of the load possible
  • The torque is the same in both directions
  • All parts are out of high strength steels
  • Continuous shaft hole
  • Flange thread in metric or inch possible
  • Non-standard options on request

The rotary actuator E3 is a specially constructed for the mobile application. This engine goes after the gear principle and needs, in case of its compact construction, a small place. The ECKART E3 finds in almost all sectors its application. Automotive engineering, building – and civil engineering, tool machines and so on.
For example staging:
If the rotary actuator is the bearing for the complete bearing pressure and the rotating mechanism integrated. Therefore the working platform must not be mounted separately. Furthermore has the rotary actuator a hole, where tubes or cables can put through. In case of safety regulations reasons can there be put through a screw with the screws will be the plates from the brackets or from the working platform extra field. Even by a damage of the rotary actuator, for example in axial direction can the working platform not be detached.
That even by a sideways action of the working platform in each between position, a waggle of the platform not happens, will be for first the turning threads free from backlash, second the ball bearing free from backlash build in, and thirdly there will be not used any both-way compact seals.

Furthermore ECKART offers valve block, which can be mounted with hollow screws on to the pressure connection holes.

The valve has furthermore the following functions:

  • Loading hold function:
    If the working platform wants to lower in case of diagonally position.
  • Clamp function:
    That the working platform does not shake by any holding position.
  • Overpressure function:
    That overpressure, is it in case of the hydraulic system or in case of temperature range, does not destroy the actuator.
