Abstract

A rodless cylinder assembly comprises a cylinder barrel provided with an axial bore in which a piston is slidably fitted and a slit formed in the outer surface thereof so as to be directed upwardly. A slide mount is operatively connected to the piston through connecting member integrally formed with the piston and projecting outwardly through the slit to be slidable along the upper surface of the cylinder barrel in an axial direction in accordance with the movement of the piston. The slide mount is slid along first guide rails disposed on the upper surface of the cylinder barrel at both sides of the slit and along second guide rail formed in opposite side walls of the cylinder barrel. Guide members are disposed between the second guide rails and side depending walls portions of the slide mount and the clearance between the second guide rails and the guide members can be adjusted by screw means. Each of the second guide rails has a guide surface inclined inwardly towards a cross-sectionally central portion of the cylinder barrel. The above construction makes it possible to cause the slide mount to move smoothly along the cylinder barrel irrespective of external forces acting on the …
