Pulling, pushing or pressing up to 1,000 kg

IAI rod type actuators and radial cylinders are characterised by their compact design, mechanical stability and high positioning accuracy of up to ± 5 μm.

In addition to the standard version, rod type actuators are also available as short-stroke and heavy-duty actuators as well as radial cylinders with normal and wide base frames. For strokes up to a maximum of 800 mm, they can precisely position payloads of up to 1,000 kg horizontally and up to 600 kg vertically.

Radial cylinders with built-in linear guides

In contrast to rod type actuators, radial cylinders are equipped with built-in linear guides that absorb axial and radial loads. Vibrations during stopping are thus suppressed.

Wide radial cylinders can absorb four times the permissible torque at the rod end compared to a standard radial cylinder due to the built-in guides and the wide base frame.

With its high permissible dynamic moment, the wide radial cylinder is ideal, for example, for tightening and stirring with high load torque or as a movable vertical axis of a Cartesian system.

Model variants & special versions

Many rod type actuators and radial cylinders are available in two design variants: As a directly driven cylinder with motor in extension of the longitudinal axis as well as a shorter variant with deflection, where motor and axis are parallel to each other.

Electric rod type cylinders are also available for cleanrooms and as IP-protected models for dusty or humid production environments.

Battery-free absolute encoder

The latest RoboCylinder series are equipped with a battery-free, high-resolution absolute encoder as standard.

This means that no reference point has to be approached in the event of an emergency shutdown or operating error, and downtimes are reduced. With a battery-free absolute encoder, there is also no need for maintenance and replacement of the back-up battery, which is used for position storage.

Advantages of battery-free absolute encoders:

  • No reference point travels are necessary.
  • No external home sensor required.
  • No workpieces have to be removed after an emergency stop.
  • No battery change and therefore no battery disposal.
