Tsiatim-203 grease (GOST 6267-74) - the scope of application; gear, worm gear reducers, slide supports and rolling bearings; various power drives, screw pairs, loaded gearboxes, mechanisms operated on the open areas, friction units of cars. Exceeds Tsiatim-201 (temperatures from –50 to + 100°С).
There have been cases of effective using Tsiatim-201 as a replacement of shoe polish when lubricating leather shoes - this material has water-repellent properties, almost does not dissolve in water. Tsiatim -201 grease is produced in accordance with GOST 6267-74 and is used to lubricate friction, sliding and rolling units: in aeronautical equipment (the widest scope of application), automotive and other ground equipment, radio equipment, electromechanical and precision instruments operating with minimal resistance at low temperatures. It is not recommended to use it at high loads. Due to its low-temperature characteristics, the grease is actively applied to the mechanisms of equipment operated in the Far North. This lubricant, in the opinion of a certain target audience, is the most convenient in terms of processing rubbing parts and mechanisms of hunting rifles: barrels, locks, sliding surfaces, firing mechanisms, which explains its chemical stability.
