ABSTRACT:
A rotary linear unit possesses a rotary drive and a linear drive. A bearing rod is connected with the drive shaft of the rotary drive, such bearing rod extending coaxially into the output drive unit of the linear drive. On the bearing rod a bearing sleeve is mounted so that it may not rotate while being axially displaceable, such sleeve being fixedly connected with the piston of the linear drive. The piston is divided into two axially sequential piston parts, between which the bearing sleeve is located, which extends into facing receiving recesses in the piston parts.
