The procedure for tests of contact creep in ring bearing-samples is developed and also a generalized diagram of residual stresses formation after babbitting and machining a babbit layer in bearings is obtained. It is shown that the existence of a cyclic deformation of an antifriction layer results in a complete relaxation of the sum of all constant constituents of residual stresses. It is concluded that the main reason of the dissi-pation of strength characteristics in babbit samples consists in rheological properties of this material.
