Article is dedicated to increasing the wear resistance joints manipulator process equipment by constructive exclusion reversibility friction and applying mechanisms automatic wear compensation. Such changes can significantly increase the service life of hinges and are recommended for use in the design of process equipment attachments.

The analysis of the types of wear and durability factors hinge manipulators for example manipulators forest machines. The possibility of using anti-friction plastics as anti-friction material in the joints of manipulators. The theoretical justification for their performance. Fundamentally reviewed the existing equipment for the production of plastics. The conclusions about the possibility of using self-lubricating anti-friction plastic, and recommendations.

The paper studies the wear of backing material, depending on the direction of the warp.

To describe the frictional interaction of a powder coating with a metal counterbody under steady wear, a statistical model has been developed based on the binomial distribution of removed wear particles. In the model, the deletion events of coating and counterbody particles are optional. It is assumed that the Bernoulli test corresponds to the friction path. The proposed statistical approach to the description of the steady wear of a powder coating and a counterbody under sliding friction based on the local Moivre-Laplace theorem provides a statistical justification for the normality of the distribution of the profiles of the equilibrium friction surfaces of the coating and the counterbody.

To describe the frictional interaction of a powder coating with a metal counterbody under steady wear, a statistical model has been developed based on the binomial distribution of removed wear particles. The profilometric method was used to study the microgeometry of contact surfaces in friction units «wear-resistant coating – steel counterbody» during sliding friction at room and low climatic temperatures. The analysis of profilometric data revealed that the distribution of heights of the friction surface profiles of wear-resistant coatings and counterbodies is mainly unimodal and is characterized by symmetry.
