Double acting hollow cylinders in the RARH series in 100 and 150 ton models, with a stroke of 50 mm, 150 mm or 250 mm. The new cylinders in the RARH series have the same advantages as the 30 and 60 ton models that were previously launched from Enerpac. The cylinders are developed with an aluminum construction that provides the same solution but with a lower weight compared to steel cylinders.
