Wear of rubber sealing arrangements in cylinders depends on a number of design parameters and technological factors of working surfaces treatment. The dimension of detachable rubber particles reaches in some cases some millimeters. Such particles not only decrease cylinders reliability, but also result in a violation of efficiency of devices mating them. On the basis of the analysis of industrial experiment data are revealed the regularities of the wear products formation in rubber rings. By development testing there is shown high effectiveness in the application of the surface strengthening methods for cylinder working surfaces. The recommendations developed ensure the increase of errorfree running time of cylinders 1.8-2 times.
