The article covers the issues of increasing the level of hardness and wear resistance, reducing the level of friction resulting from sliding, or some shuttle components may have an external coating simply for the purpose of protecting against rust. The use of one or another type of coating depends on the choice of the shuttle manufacturer; in particular, hard chrome plating has been used for many years on all shuttle devices, not just on the shuttles of high-speed sewing machines. Calculations determining the effectiveness of introducing antifriction coatings on the surfaces of contacting parts have been done, in particular, tribological couplings of the shuttle socket with a bobbin have been studied in detail, which leads to an improvement in the temperature conditions of operation in the contact zone and, as a consequence, to a reduction in wear of the surfaces of contacting parts and an increase in the durability of tribological couplings.
