It is shown that one of the reasons for the failure of the SSHNU is the wear of the connecting rods with the crank, due to uneven loads on the connecting rods, due to the inaccuracy of the manufacture of elements of kinematic pairs, leading to elastic deformation and an increase in friction forces. The replacement of connecting rods with a crank and a traverse with spherical plain bearings corresponding to kinematic pairs of class IV, which exclude elastic deformations of the links, due to the appearance of an additional degree of freedom, is proposed. Calculations show an increase in the service life of spherical plain bearings by 15-17%.
