ABSTRACT:
A rodless cylinder for feeding a workpiece has a cylinder having a cylinder tube with a bore defined therein and a piston reciprocally movably disposed in the bore. The cylinder tube has a slit defined therein and extending longitudinally therealong, the slit communicating between the bore and an exterior space. The slit is closed by a first seal member engaging the piston and a second seal member engaging a slide table. The piston has a separator separating the first and second seal members from each other. The cylinder tube has a pair of slanted first surfaces positioned one on each side of the slit. A pair of slide members is disposed on the slide table and have respective second surfaces engaging the first surfaces, respectively, for guiding the slide table when the piston reciprocally moves in the bore and bearing a load applied to the slide table. The rodless cylinder may additionally have a floating mechanism mounted on the slide table for allowing displacements substantially perpendicular to the direction in which the slide table is movable along the cylinder tube.
