Numerous factors influence the tribological wear of steel rollers used in conveyor belts. The difficulty in precise determination of these factors results from, among others, a complex and not completely explored wear mechanism. Corrosive and fatigue damages of conveyor belt rollers start mainly on the surface. The present article describes studies on the influence of processing technology of the roller surface by means of the shot peening method in the context of fatigue strength improvement. Compressive stresses formed due to shot peening reach the maximum value just below the roller surface. The values of compressive stresses reach about half of the proof stress of the steel from which they are made. In results of the carried out experimental model tests, it was found that it is possible to significantly improve the properties of the top surface layer of the roller surface, and especially to increase fatigue strength, fatigue corrosion resistance, resistance to cracking caused by stress corrosion, and the like.
