The article proposes to consider the solution of the axisymmetric problem in Lame in polar coordinates to determine temperature and humidity stresses during heating-NII (cooling) and drying (swelling) of anisotropic friction bearings of modified wood, loaded with internal and ex-ternal pressure. The underestimation of temperature and humidity stress can lead to heavy wear, and in some cases to the destruction of the sliding bearings. Solution of the problem is presented in a form convenient for engineering calculations.
