The compare the durability of the existing ball bearings (SHO) with the polymer homogeneous element with the durability of the modified supports, a cell model with the averaged placement of the modifier in SHO substrate and a model for bringing the multilayer sho body to the equivalent single-layer one are constructed; calculations of contact pressure, contact deformations and stresses are performed. The calculation takes into account the rheological and physico-chemical properties of the components of SHO substrate and modifier, the influence of the environment. As a result of calculations, it was found that at all points of the contour the material experiences a biaxial plane two-dimensional stress state, called pure shear with the presence of shear stresses. The most intense point of danger is the point lying in the center of the platform of contact of details.
