Optimization of the radial bearing geometry by the dimensional analysis

Abstract In order to improve the working capacity and life of bearing units, dimensional analysis inner geometry a cylindrical radial was carried out. The assembly component, composed by outer diameter dimensions raceway race, race two diameters rollers, considered as dimension chain. It is recommended, in reduce wear friction losses, produce diametrical roller according fifth accuracy degree. established that cause axial clearance between double-flanged distance contact points on right left flanges with horizontal position roller, well diagonal distance. Tolerances for ring dimensions, such combination, are recommended accept respect degree 6.
