FAQ

Q1: How often should I check or maintain my excavator hydraulic cylinder?
A1: It’s recommended to inspect your hydraulic cylinder every 250–500 working hours. Check for oil leaks, wear on seals, scratches on the rod, and ensure mounting bolts are secure. Preventive maintenance can significantly extend the cylinder’s service life.

Q2: What are the signs that my hydraulic cylinder needs repair or replacement?
A2: Common signs include:

Oil leakage around the seals

Weak or slow movement of the excavator arm

Abnormal noises or vibrations

Rod surface damage (scratches or rust)

Unusual heating of the cylinder

If you notice any of these issues, stop usage and contact a technician immediately.

Q3: How do I clean the hydraulic cylinder properly before maintenance?
A3: Use a lint-free cloth to wipe off dust and oil around the cylinder. Avoid high-pressure washing directly on the seals. Make sure to clean the rod before retracting it to prevent dirt from entering the cylinder chamber.

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.
