Rotary actuators

 

Rotary actuators > 1.Rotary actuator SM4


- extremely powerful and scalable -


The SM4 is a rotary actuator and functions according to the "helical gear" principle.

How often have you searched for a rotary unit capable of executing a rotary movement  or a limited rotational movement in an extremely small installation space? Frequently? If so, then Eckart can offer the perfect solution with its current 250-bar rotary actuator, the small and compact SM4.

A rotary actuator should not only be able to execute a simple rotational movement, however, but also perform functions that otherwise require additional investment and complex technology.


Product advantage

  • operating pressure up to 250 bar, torques up to 250,000 Nm
  • 4 standard rotation angle 90 ° / 180 ° / 270 ° / 360°
  • continuous drive shaft
  • wear resistant sliding surfaces

additional features:

  • end cushioning
  • locating pin on the end of the shaft
  • switching elements for angular interrogation
  • various shaft types, such as DIN5480 gear shaft, gear hub, hollow shaft

and of course special designs according to the request of the customer

  • drive shaft smooth, involute spline, rectangular, ...
  • second drive pivot at the bottom
  • angle adjustment over the entire rotary range
  • change of the direction of rotation
  • direct connection of valves
  • each between-rotation-angle, even above 360 °
  • operating pressures above 250 bar
  • special colors
  • lake and saltwater resistance
  • ...

Based on the SM4 we realize special designs which are tuned to your exact needs. Our engineers find your solution.

 

Rotary actuators > 2.Rotary actuator E1

- setting the standard for low-pressure hydraulic systems -

The E1 rotary actuator is the latest rotary actuator in our product range. With regard to application, low-pressure hydraulic systems, with typical pressure ratings of 40, 60, 80 or 100 bar, are of relevance here.

The E1 functions according to the "helical gear" principle and, due to its compact design, only requires a minimum amount of space. The diverse options offer a maximum degree of flexibility and functionality. With the E1, Eckart offers you a high-performance series, allowing optimal adaptation to your particular requirements.

The Eckart E1 is the official successor to the classical SM1 rotary actuator; this motor, first introduced more than 30 years ago, has undergone several developments and been used in over 100,000 installations. Concerning development of the SM1, a large emphasis was placed on reducing the installation dimensions while at the same time ensuring replaceability.


Product advantage

  • smallest installation dimensions
  • ultracompact
  • robust
  • wear resistant
  • effective end cushioning
  • adjustable drive shaft datum

 

Specifications

standards:

  • operating pressure up to 100 bar
  • 5 models of pistons Ø 40 - 125 mm
  • 4 standard rotation angle 90°/180°/270°/360°
  • adjustable drive shaft datum
  • continuous drive shaft
  • wear resistant sliding surfaces

additional features:

  • end cushioning
  • angle adjustment ± 5°
  • flange attachement
  • foot model
  • locating pin on the end of the shaft
  • switching elements for angular interrogation
  • various shaft types, such as DIN5480 gear shaft, gear hub, hollow shaft

 

Rotary actuators > 3.Rotary actuator E3

- for mobile applications -

The E3 is a hydraulic rotary actuator that has been especially designed for mobile applications. This rotary actuator functions according to the "helical gear" principle and, due to its compact design, only requires a minimum amount of space.

As far as the dimensions are concerned, the Eckart E3 is identical in form to the products of its competitors. The Eckart E3 rotary actuator has unique selling points, however, which can offer decisive advantages during its application: firstly, the deflection threads are paired with virtually no play; secondly, the roller bearing is fitted so that there is no play; and thirdly,  no compact seals which can be subjected to stress on both sides are used. Consequently, there is no more "wobbling", such as of the work platform, when a lateral movement is made.


Product advantage

  • ultra compact
  • robust construction
  • high bearing charge
  • exact, almost free from backlash positioning
  • double shaft-and piston-sealing (lip seal)

 

Specifications

standards:

  • operating pressure up to 210 bar
  • torques up to 3.600 Nm
  • 2 standard-rotation angle 180°/360°
  • continuous drive shaft
  • wear resistant sliding surfaces

additional features:

Valve block with

  • loading hold function, in case there is a tendency for the work platform to rapidly move away if positioned on an incline.
  • clamp function,so that the work platform cannot wobble from side to side regardless of its stop position.
  • overpressure function, which prevents the rotary actuator being irreparably damaged due to excess pressure, stemming either from the hydraulic system or from an increase in temperature.


- Special designs in accordance with customer requirements

Use of work platform:
Bearings for the full accommodation of the load and the rotary mechanism are integrated in the rotary actuator. Consequently, the work platform must not to be separately fitted with bearings. Furthermore, the rotary actuator has a hole through which the hoses or cables can be passed. For safety reasons, it is also possible for a screw to be fitted at this hole. With this screw, extra tightening at the fastening straps of the extension arm or the work platform can be provided. Even if the rotary actuator is damaged, e.g. in the axial direction, the work platform will remain fixed in place.

 

Rotary actuators > 4.Rotary actuator PSM2

- ultra-light -

The PSM2 is a pneumatic rotary actuaor that works according to the principle of the dual curve-roller deflection, and is most suited to applications in small installation spaces and with low weight requirements.

High-quality aluminium alloys and modified plastics are used as materials. As a result of this material combination, the rotary actuator has an extremely low weight. The sizes/operating widths vary, with diameters ranging from 40 mm to 100 mm, and a torque of up to 80 Nm at an operating pressure of 6 bar can be achieved. The maximum operating pressure is 10 bar.

Due to the design of the standard drive shaft with a key hub, it is possible to insert a so-called thread adaptor or a hub adaptor, depending on requirements, which can then be equipped with all manner of connecting profiles, such as gear-shaft, rectangular, hexagonal, cylindrical and polygonal profiles.

Product advantage

  • principle roller deflection
  • rotation angle up to 360° or more
  • adjustable drive shaft datum
  • compatible thread adapter

 

Specifications

standards:

  • operating pressure up to 10 bar

  • angle adjustment  ± 5°
  • continuous drive shaft
  • wear resistant sliding surfaces

additional features:

  • locating pin on the end of the shaft
  • manual operation
  • switching elements for angular interrogation
  • various shaft types, such as DIN5480 gear shaft, gear hub, hollow shaft
  • special designs according to the request of the customer
