COMMON CAUSES OF CYLINDER FAILURE
High usage and harsh site conditions contribute significantly to cylinder failure. Impact, corrosion, and abrasion all take their toll, leading to serious machine performance issues. Surprisingly, 75-85% of hydraulic system failures are traced to contamination issues. Simply keeping your hydraulic fluid clean through smart contamination control practices can significantly reduce cylinder failures and repair/replacement costs.
Why is Contamination Prevention Important?
Preventing cylinder contamination and choosing the right repair option can save you time and money. Contamination control is crucial for maintaining a healthy hydraulic system. Surface damage to cylinder rods, such as scoring, pitting, or denting, is a common entry point for contaminants, leading to costly repairs and reduced efficiency. Regular maintenance and inspections help proactively manage potential hydraulic system issues. If any damage is identified, selecting the right repair option is essential. By investing in the right solution, you can reduce the risk of further contamination, protect the integrity of your hydraulic system, and save time and money.
