Festo presents the DRRD semi-rotary drives with piston designed to set new standards in process automation.
Up to 20% cheaper than comparable products, the DRRD is set to replace the DRQD in the medium term.
The sturdy bearing of the DRRD pneumatic drives improves their service life as well as cost-effectiveness. Internal shock absorbers guarantee very high mass moments of inertia, while external shock absorbers ensure full torque in the end position.
The precise concentricity on the flange shaft offers greater precision for positioning, even with a long lever arm. Optimised dimensions facilitate the integration of the semi-rotary drives with piston in compact machines while simple adjustment speeds up the commissioning process.
