IAI RCP6 ROBO Cylinder Review: Specs and Uses of the Electric Actuator Series
Updated: 7 days ago

The IAI RCP6 ROBO Cylinder is a range of electric actuators that replace air cylinders where position control is needed. The manufacturer does not publish a price. This review covers its specifications, features and uses.
Quick Verdict
The RCP6 is a building block more than a robot: single electric axes in six types (slider, wide slider, rod, radial cylinder, wide radial cylinder and table), each with coupled or side-mounted motors. Sliders reach 1100 mm of stroke, 80 kg horizontally and 1440 mm/s; wide sliders and rods carry up to 100 kg. Repeatability is ±0.005 mm on coupled sliders and ±0.01 mm elsewhere, twice as good as IAI's previous series. A battery-less absolute encoder is standard at no extra cost, and the RCP6S versions have the controller built in, with up to 16 axes on one gateway. The page does not give push force.

Design and Build Quality

Body widths run from 40 to 160 mm. Wide sliders accept about 14 times the moment of standard sliders, and cleanroom and dust/splash-proof versions are available.
Software and Integration
PowerCON Controllers
High-output drivers raise stepper output and shorten cycles.
RCP6S Built-In Controller
Up to 16 axes connect to one gateway with a single cable for power and communication.
