Description
The Festo DRRD Series Semi-rotary Drive has twin pistons with power transmission via the rack and pinion principle. It combines great load-carrying capacity and accuracy with excellent economic efficiency. It is available in sizes 8 to 63 and provides the required torque of 1.6 to 24.1Nm even with comparatively small dimensions. The DRRD comes with one of two internal cushioning types, elastic or hydraulic, and external hydraulic cushioning. A soft or hard internal shock absorber is available for sizes 25 and above.
The DRRD Series has a higher maximum mass moment of inertia and bearing loads, allowing a size smaller to be used while providing the same performance. This helps save money and installation space in handling or assembly technology, and with general or machine tool construction. Its optimized housing and piston drive design make it ideal for the rough and tumble of everyday industrial use. From size 16 onward, there are options for mechanical locking in the end or middle position, as well as a completely sealed version for humid environments.
