How long does the excavator hydraulic cylinder last?

The lifespan of an excavator hydraulic cylinder depends on factors such as operating conditions, load frequency, and maintenance practices. With proper care, a cylinder can last 5 to 15 years, but poor handling or neglect may shorten its service life significantly.

High-quality cylinders are capable of withstanding over 2.5 million cycles per year. However, as the equipment ages, wear on components like the piston increases the risk of leakage, often requiring timely repair or replacement to maintain performance.
