3 Ways to Reduce Hydraulic Cylinder Failure and Repair Costs
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 in four hydraulic cylinders are not adequately designed for the application they’re operating in. This doesn’t mean that the cylinder won’t do the job asked of it, it will - but not with an acceptable service life. So if you have any cylinders that don’t last like they should you may need to address one or more of the following four issues: 1 . Rod Finish — The surface finish of the cylinder rod has a significant effect on the life of the rod seal. If the surface roughness is too low (smooth), seal life can be reduced as a result of inadequate lubrication. If the surface roughness is too high, contaminant ingression is increased and an unacceptable level of leakage past the rod seal can result. In the context of extending cylinder service life, think of the cylinder rod’s surface as a lubricated, wear-surface and treat it a...
