Compact Rotary Actuators and Gripping Units

Many different designs, sizes and options

Precise rotary actuators for almost all applications

To meet the wide range of requirements in terms of mass moment of inertia, lead and payload, there is a comprehensive range of rotary acutators from the RCP2 and EleCylinder series with 24V stepper motor and the RCS2 series with 230 Vservo motor.

RCP6 rotary grippers, which combine motorized rotating and gripping in one unit, complete the product range.

Multi-turn operations

Many models have multiple rotation specifications that allow rotations exceeding 360 degrees. There are two different specifications available, the index mode and the normal mode.

With the index mode the axis works like an index table allowing rotation with unlimited degree made from small single rotations up to 360 degrees with short stops between each of them. The normal mode works on the same principle as a linear actuator and allows free rotation between ±9999 degrees without having to stop.

RCS2 Hollow rotary types for high-precision positioning

The RCS2 hollow rotary type actuators have a large-diameter hollow structure, that allows installation of rotating wires and laying of pipes easier.

The model range consists of three sizes with widths of 85, 99 and 123 mm and hollow shaft diameters of 30, 40 and 54 mm. Especially the other key data predestines the RCS2-RTC rotation axes for highly dynamic and precise positioning tasks:

  • ± 9999° rotation stroke
  • ± 0.005° repeatability
  • 1200°/s max. Speed ​​of rotation
  • 25 Nm max. load torque
  • 800 N max. holding force

Therefore, the RCS2 rotary axes are widely used for demanding applications, such as silicon crystal pulling in the semiconductor industry or precise grinding and polishing applications that require an extremely high transmission speed in the angular second range.

 

Slim RCP6 hollow shaft rotary actuators

Slim and lightweight RCP6-RTFML Rotary actuators with large-diameter hollow shaft of ø49 is suitable for combined axes. Wiring can be passed through the hollow section, reducing the design and assembly processes.

It can be used as a shaft for rotating grippers and wrist units. Moreover, it can be combined with cartesian 3-axis and wrist unit rotational 2-axis to enable movement with 6 axes of freedom.

Rotary chuck unit - rotation and gripping

RCP6-RTCKMR Rotary Chuck

The RCP6 rotary chucks consolidate motorized rotation and gripping movement in a single unit. The rotating axis can perform multipoint positioning between 0 and 360° (one rotation). The rotational speed and acceleration/deceleration can also be set to any value.

The chuck module is small and lightweight, as a solenoid gripper is used. Furthermore, the battery-less absolute encoder equipped means that home return is not required.
