This paper presents a method of calculating the hydrodynamic radial slide bearing runs on the lubricant that has both viscoplasticity properties. When developing the analysis model as the initial equations the nonlinear Maxwell model with the existence of the limit shear stress. Asymptotic solution of the problem was found in even powers of the parameter due to the presence of limiting shear stress of the lubricant. Found the velocity field and the pressure in the lubricating layer obtained analytical expression for the bearing capacity of the bearing. The estimation of influence of parameters characterizing the elastic properties of the lubricant (the Deborah number) and a dimensionless parameter characterizing the viscoelastic properties of the lubricant parameter (plasticity) on the bearing capacity of the radial bearing.

Keywords: radial bearing, bearing capacity, ultimate shear stress, the parameter of plasticity, deformation
