Lift Cylinder Failure Analysis
\nRoot Cause & Rebuild
\nvs Replace Decision Guide<\/span><\/h1>\n

A hydraulic lift cylinder that fails repeatedly is not a product quality problem \u2014 it is a symptom of an unresolved root cause that will destroy every replacement lift cylinder until the underlying condition is corrected. This guide provides a systematic failure analysis methodology: reading the physical evidence left by the failed components, mapping that evidence to specific root causes, determining whether rebuilding or replacing the lift cylinder is the economically correct decision, and implementing the corrective action that prevents the same failure from recurring.<\/p>\n

CONTAMINATION<\/p>\n

72%<\/p>\n

Of all hydraulic lift cylinder failures have contaminated oil as a contributing or primary cause<\/p>\n<\/div>\n

\n

MISALIGNMENT<\/p>\n

14%<\/p>\n

Side loading from installation misalignment \u2014 primarily rod seal and barrel failures<\/p>\n<\/div>\n

\n

OVERLOAD<\/p>\n

8%<\/p>\n

Structural failures from loads exceeding the cylinder’s rated capacity \u2014 often from relief valve misconfiguration<\/p>\n<\/div>\n
