Understanding the Average Lifespan of a Hydraulic Cylinder
Hydraulic cylinders are the workhorses of many industrial and construction type equipment, converting hydraulic energy into linear motion. Hydraulics move everything from excavators, to factory presses. It’s common for operators and owners of machinery to ask “How long will my hydraulic cylinder last?”
Of course, there is no easy answer. On average, a maintenance hydraulic cylinder can last anywhere from 5,000 hours to 15,000 hours of operation. But, it depends on several important factors.
1. Quality of Parts: High-quality cylinders will outlast low grade components, such as seal, rods and barrels. The better the parts, the longer the cylinder will last. Spending more on components will increase the longevity of the cylinder.
2. Environment: A cylinder in a dirty, wet, hot, or heavy loaded environment will wear much more quickly than other cylinders in less harsh environments. Protecting the cylinder with a shield, lubricating the cylinder appropriately, and, if possible, putting the cylinder on a regular maintenance cycle will help towards a long life cycle of the parts.
3. Maintenance: Maintenance is the key to longevity! An operator should maintain an eye on parts, and notify someone if any issues arise. This includes cleanliness of oil, the condition of the seals, and the surface condition of the rods will go a long way to minimizing premature failure. Operations controls these factors, and a little regular maintenance can help reduce a lot of longevity issues. Small issues arise if there is no attention paid to them, and can escalate very quickly.
4. Using Load and Use Cycle: Putting loads above the design limits for the cylinder, or using a cylinder beyond its stroke or requested pump pressure will drastically affect cylinder life. Smooth and continuous usage will allow the cylinder a long life cycle for that equipment.
For companies that use hydraulic machinery, knowing these facts is more than just technical knowledge; it's a commitment to efficiency, safety, and ultimately to a cost-effective solution.
