FAQ
Q1: Can overloading damage the hydraulic cylinder?
A1: Yes. Operating the machine beyond its rated pressure or lifting capacity can cause seal failure, rod bending, or internal damage. Always follow your excavator's operational limits.
Q2: What kind of hydraulic oil should I use with your cylinders?
A2: We recommend anti-wear hydraulic oils like ISO VG 46 or 68, depending on your working environment. Always make sure the oil is clean and free from contamination, as dirty oil is a major cause of cylinder failure.
Q3: Can I replace the seals myself?
A3: Yes, if you have basic mechanical knowledge and tools. We provide step-by-step instructions or tutorial videos. However, if you’re unsure, we recommend having it done by a professional to avoid internal damage.
Q4: How can I prevent rust or corrosion on the cylinder rod during storage?
A4: Apply rust-proof oil or grease to the rod and store the cylinder in a dry, covered place. Avoid exposure to moisture or rain. If storing long-term, operate the rod regularly to keep the seals lubricated.
Q5: How long do your hydraulic cylinders typically last?
A5: Under normal operating conditions and with proper maintenance, our hydraulic cylinders can last 3–5 years or longer. Lifespan also depends on working environment, usage frequency, and hydraulic oil quality.
