*Models without air cushion are designed to include rubber bumpers.
Since the bumpers are attached to the both sides of the piston, the overall length is longer than the cylinder with air cushion as follows: ø32 (32‑mm bore size), ø40 (40‑mm bore size): 6 mm; ø50 (50‑mm bore size), ø63 (63‑mm bore size): 8 mm; ø80 (80‑mm bore size), ø100 (100‑mm bore size): 10 mm.
