R4 Series

The R4 Series is our most powerful rodless actuators system, built for the heaviest loads, high acceleration and maximum duty cycle. The robust design incorporates an internal linear motion guide rail with a built-in flexible seal to ensure reliable operation in industrial environments. Belt-drive models offer the most rapid moves while screw drives offer the highest thrust capacity and repeatability.
