Welded Hydraulic Cylinder

Welded hydraulic cylinders have no tie rods. Instead, the barrel is welded directly to the end caps and the ports are welded to the barrel. The front rod gland is generally bolted or threaded into the cylinder barrel, which allows the piston rod assembly and the rod seals to be removed for service.Welded cylinders are cylinders in which the barrel is directly welded to the end caps, and on the other end, the main tube is welded directly to the base plug; there are also cross tubes that are welded to the piston end. These welded elements eliminate the need for tie rods and strengthen the cylinder overall.Welded hydraulic cylinders have a more complex design compared with tie rod cylinders as one cap is typically welded directly to barrel and the other cap is threaded or locked on the barrel. In this design, the mounts and other cylinder fittings are also welded directly to the cylinder.
