Fluid activated drum cylinder

摘要

The fluid activated drum has a side face arrangement, piston rods, a guiding device with a non-round cross section that in itself has guiding ends (16). The piston rods (8) cross axially through the drum. The casing is underpropped with a periphery (15) of the guiding sides that co act with a rolling bearing mechanism. The periphery of the guiding sides of the piston is made from an axially extending flat plate section. A circumference device is fastened onto the cross cylinder shaped cylinder sides. The rolling bearing mechanism has a spherical ball sleeve attached to the guide section and co-axially surrounding the cylinder section.
