Abstract
A drive and guide means for a load to be moved which comprises a rodless drive piston adapted to be driven by a pressure medium in a pressure medium cylinder, such piston having at least one force transmission part extending outward through a longitudinal slot in a wall of such cylinder. A flexible sealing tape for seals off the longitudinal slot on either side of the force transmission part. An anti-friction bearing arrangement serves to take up a load and/or to guide the piston, such anti-friction bearing arrangement being arranged in the housing of the pressure medium cylinder. An anti-friction bearing arrangement is arranged within the cylinder space of the pressure medium cylinder in or on the drive piston. This means that pressure medium cylinders with an extremely small cross section and an extremely simple structure may be produced economically.
