Oil TSZP-8 (TU 38.1011280-89) - low-viscosity, low-solidification, thickened with a viscous additives resistant to destructive actions , also contains an extreme pressure additive. Oil TSZP-8 is a solvent-extracted oil. Contains additives that improve antiwear, anti-corrosion, extreme pressure, antioxidant, viscosity-temperature and antifoam properties of the oil, ensuring its reliable operation under conditions of high sliding speeds, pressures and a wide temperature range.
TSzp-8 is a long-life transmission oil intended for lubrication of transmission planetary gear set, as well as some hydraulic control systems of mobile vehicles. These are transmissions of transport machines, spur, spiral-bevel and worm gears operating under contact stresses up to 20000 kg/cm2.
The efficiency of TSzp-8 is maintained at oil temperatures up to +120°С and at ambient temperatures up to -50°С.
The oil ensures reliable and long-term operation of transmission units. Retains performance characteristics during long-term storage.
According to GOST 17479.2-85, TSzp-8 oil corresponds to TM-3-9. ТSzp-8 meets the requirements of SAE 75W-80 and API GL-3.
