R3 Series
R3 Series rodless actuators provide a robust design with an internal linear motion guide rail and built-in flexible seal to ensure reliable operation in industrial environments. Equipped for high loads or high acceleration with maximum duty cycle, the R3 Series is available with either belt drive for the most rapid moves or screw drive for the highest thrust capacity and repeatability.
