Present paper aims to present the measuring process and results regarding roughness of the inner surface of a truck cylinder, according to standard [5] To that purpose, it was used a Surtronic S-Series roughness tester, with a stylus able to measure within the range 400 µm. According to the before-mentioned standard, there were performed 4 measurements on the same circular line, each one shifted by 90 degrees to the previous. The process was repeated on eight functional areas characteristic to the cylinder (entire length was divided into eight equal parts). With the use of measured values it was possible to analyze whether the cylinder's inner surface had proper roughness according to specific standards, even after several functioning cycles.
