The Enerpac RAS504B is a 50-ton aluminum hydraulic cylinder with a 4" stroke and a single-acting spring return. It is half the weight of steel cylinders and features a heavy-duty spring for fast and full retraction. The large bearing surfaces are for side load protection. The technical coating reduces wear and corrosion. The cylinder also has to stop rings for piston blowout protection, and its rod wiper protects the inner cylinder from dirt.
