How Do You Choose the Right Hydraulic Cylinder Seals for Reliable Performance?
To choose the right hydraulic cylinder seals, you need to look beyond the seal size. You should match the seal material and design to your cylinder's pressure, temperature, operating speed, hydraulic fluid, rod and bore dimensions, duty cycle, and installation conditions. Getting any of these factors wrong can lead to leakage, premature wear, higher friction, contamination, and unexpected downtime. Hydraulic cylinder seals may be small components, but they have a major role in keeping a hydraulic system reliable. A cylinder can have a strong barrel, accurately machined rod, and properly sized piston, yet still perform poorly if its seals are unsuitable for the application. That is why seal selection should be treated as an engineering decision rather than a simple replacement-parts purchase. ISO 5597:2018 provides preferred dimensions and tolerances for housings used with piston and rod seals in reciprocating hydraulic cylinder applications. Importantly, the standard also notes th...
