For Den Herder Seaworks, we overhauled this cylinder with a new rod, a welded rod eye, and a spherical bearing. Spherical bearings can carry a lot of weight. This makes them extremely suitable for use in high, static loads. The cylinder is used on a ship for the extraction of sand and gravel. We provided extra protection at sea against sun, wind, rain, hail, and snow with a nickel-chrome layer.
