Symptoms of Common Hydraulic Problems and Their Root Causes

The consequences of cavitation in a hydraulic system can be serious. Cavitation causes metal erosion, which damages hydraulic components and contaminates the fluid. In extreme cases, cavitation can cause mechanical failure of system components. While cavitation can occur just about anywhere within a hydraulic circuit, it commonly occurs at the.
