Compact air-over-oil cylinders

HyperCyl HZ Series hydra-pneumatic drives produce high forces and operate with a single pneumatic valve and shift to high-pressure mode without an approach stroke, reducing cycle times. Forces of 1 to 20 ton are possible. Strokes are 2 to 8 in. with power strokes of 0.25 to 1 in. Steel construction, chromed and polished surfaces, and two moving parts reduce required maintenance.
