In order to study the influence of vibration of cylinders in local linters 5LP on the efficiency of saws, the quality of products and the productivity of the linter, studies were carried out on technical seeds of the Sultan selection of the 1st grade, 2nd class at the Bakht cotton plant in the Syrdarya region. At the same time, according to PDI 89-2018, when using saws in a linter from 12 to 72 hours, the productivity of the linter for seeds decreased on average from 734 kg/hour to 386 kg/hour, and the productivity of the linter decreased on average from 30.4 kg/h up to 16.3 kg/h. It was found that after 12-72 hours of using new saws when linting seeds, the mass fraction of weeds and whole seeds in the linter, formed due to rapid wear of the saw teeth, increases by an average of 1.84 (abs)% and the quality of the linter decreases. When studying the degree of damage to seeds obtained from the linter, the quality of the seeds Textile Journal of Uzbekistan №1/2024 20 decreased by an average of 1.79 (abs)% during the saw operation period from 12 to 72 hours. It was found that out of 160 saws in the cylinder, 20.0% touched the upper working part of the grate without passing between the grate due to high vibration caused by the rotation of the saw cylinder at a speed of 730 rpm. When saws were operated for 12 to 72 hours, the height of the saw teeth decreased by 1.12 mm due to their touching the side of the grate, and the amount of fluff scraped off from the surface of the seed decreased due to wear of the working edge. As a result, with a decrease in the efficiency of the linter and seeds, the time spent by the seeds in the working chamber was formed, which led to an increase in the degree of damage to the seeds.
