Abstract
The article analyzes the exploitation reliability of hydraulic cylinders. Hydraulic cylinders fail due to oil leakage as a result of material wear and tear with 90 bar oil pressure. Empirical data (statistical sample) were collected to determine the failure density function f (t), the hazard function λ (t) and the expected value of mean time to failure MTTF. The numerical model was created in the Minitab 16 software tool. The Anderson-Darling test was used to accept or reject the hypothesis
