Hydraulic cylinders are almost as common as pumps and motors combined. So if you operate any hydraulic equipment, it’s likely that cylinder repair expense is a significant portion of its total operating cost.
According to some studies, up to 25% of mechanical equipment failures are failures of design. If we apply this to hydraulic cylinders, then as many as one … Read more
Protecting the surface of hydraulic cylinder rods when a machine is idle is particularly important in corrosive environments, such as marine or offshore applications. And even more so if the cylinder rod is finished with conventional, hard chrome plating, which due to its micro porosity, has relatively poor corrosion resistance. The BEST way to keep the surface of the cylinder … Read more
One of our members wrote me this question:
“In hydraulic systems and in hydraulic components in particular, bolts are everywhere. Should we change bolts every time we open them, for example, on a hydraulic cylinder head joint? If not, how many times can bolts be re-torqued?”
Unlike bolts used on engine heads, most of the bolts used to assemble hydraulic … Read more
