The methodology for analytical calculation of the size of the contact arc of the cage as an elastic ring with a rigid locator ring of cylindrical roller bearing is developed, which has allowed to make the calculation scheme of the cage more precise by replacing point contact by the arc. The influence of the size of contact arc of the cage with the locator ring depending on the cage rigidity and the gap between the cage and the locator ring is investigated. Scientific novelty of the work consists in the first proposed methodology for analytical calculation of the contact arc of the cage with the locator ring of the bearing, formed under the load from the rollers, and the practical value of the work lies in improving the accuracy of calculating stresses in the weak section of the solid structure of the cage and improving the efficiency of its designing.
