Twin Piston Semi-Rotary Drive, DRRD

Festo has launched a Twin Piston Semi-Rotary Drive DRRD for powerful, precise and economical positioning. The DRRD offers extremely precise positioning in the end positions, including with long lever arms. The twin piston semi-rotary drive DRRD facilitates extremely precise positioning in the end positions, including with long lever arms. Other features are its high load capacity at torques from 1.6 to 24.1 Nm and the high maximum mass moment of inertia of up to 67,000 kg/cm², even in compact sizes. This enables a smaller size of the powerful semi-rotary drive to be used without sacrificing any power. This saves money and space in handling and assembly technology or in machine building. The optimised housing and piston drive design of the DRRD can handle even the harshest industrial conditions day after day. As an added feature, size 16 and above of the semi-rotary drive are equipped with an end-position lock for mechanical locking in the end or mid-position. There is also a fully sealed variant for humid environments as well as one external and two internal cushioning types.
