Twin piston semi-rotary drive DRRD Power package! Highlights • Top performance for a low price • With higher load capacity and higher maximum mass moment of inertia, even in small sizes • Precise end positions, even with long lever arm The new twin-piston semi-rotary drive DRRD combines a high load capacity and accuracy with great economy. Available in several sizes, it delivers the required torque of 0.2 to 112 Nm with com paratively compact dimensions, which makes it significantly less expensive. Flexibility for economy The DRRD is available in sizes 8 to 63. Common features of all sizes are high maximum mass moments of inertia and bearing loads. These allow a drive one size smaller than usual to be selected for a given performance level, thus saving money and i nstallation space – in handling and assembly applications or in general machine construction and machine tools. Higher load capacity than ever before Thanks to an optimised housing and piston design, the DRRD is well able to handle the demands of a tough industrial environment. From size 16 onwards, it also offers the option of endposition locking as a mechanical interlock for end or intermediate positions and a completely sealed variant for wet environments. Reliable and powerful This semi-rotary drive provides precise positioning, even with a long lever arm. It beats its c ompetitors in the accuracy it offers in its end positions. Optimal cushioning With two types of internal c ushioning – elastic or hydraulic and external hydraulic cushion ing. From size 12 onwards, either a soft or hard internal shock absorber can be used.

Twin piston semi-rotary drive DRRD Cushioning Choice of different types of cushioning for different loads and swivel motions: • Elastic cushioning, with metal end position • Shock absorber External cushioning Full torque to handle maximum mass moments of inertia can be achieved in combination with external cushioning in the end positions. Position sensing Internal position sensing with proximity sensors in T-slot – flush-mounting to fit into the smallest installation space External position sensing (sensor mounting) • Position sensing possible directly at the flanged shaft • Inductive sensors...
