Abstract
The present invention relates to a fluidic cylinder. This fluidic cylinder is configured in such a manner that a piston unit is received in an axially displaceable manner within a cylinder tube formed in a rectangular cross-sectional shape. The piston unit has: a base body having the front end of a piston rod staked thereto; a wear ring having the base body received therein and having a magnet incorporated therein; and piston packing adjacent to the wear ring. The piston unit is integrally held at one end of the piston rod. The wear ring and the piston packing are formed in a rectangular cross-sectional shape corresponding to the rectangular cross-sectional shape of the cylinder tube and are provided rotatable relative to the piston rod.
