Common causes
of cylinder failure

High usage and harsh site conditions make major contributions to cylinder failure. Impact, corrosion and abrasion all take their toll, too, which can lead to serious machine performance issues. But surprisingly, 75-85% of hydraulic system failures are traced to contamination issues*. Simply keeping your hydraulic fluid clean through smart contamination control can significantly reduce cylinder failures and repair/replacement costs.
