The article considers the main failure modes of guides, in particular wear and contact fatigue, which depend
on friction between contact surfaces. The influence of tribological parameters, in particular surface roughness and
lubricating structures, on the operational characteristics of linear guides is studied. Particular attention is paid to
the dynamic behavior of guides, which determines the accuracy and stability of mechanical systems. To predict
wear, mathematical models based on the Archard and Hertz theories were used, which allow estimating load
distribution and contact deformations. The influence of lubricants, in particular molybdenum disulfide and
hexagonal boron nitride, on reducing the friction coefficient and improving antifriction properties was separately
studied. The prospects for using new materials, such as cubic boron nitride, to increase the wear resistance of
guides are considered. Methods for optimizing the load between rolling elements, which contributes to increasing
the durability of guides, are proposed. The results obtained can be used to improve the designs of high-precision
mechanical systems and reduce operating costs.
