VNIINP-219 lubricant on TU 38.101471-74 is close to VNIINP-207 lubricant, but unlike it contains a molybdenum disulfide. VNIINP-219 lubricant is efficient at a temperature of-50 … +200 °C. VNIINP-219 lubricant greases rolling bearings of electric motors and a starter generators with the raised loadings and with a frequency of rotation up to 9000 min.-1, shariko-screw gears of aircraft. Technical characteristics of VNIINP 219 the Name of an indicator Norma in accordance with GOST (TU) Appearance Uniform soft ointment from dark gray till the black Viscosity color at minus 30 °C and an average gradient of speed of deformation 10s-1 2,0 Colloidal stability, % of masses, no more than 7,0 Content of water, % of masses. there is no Mass fraction of free alkali, %, no more than 0,08 Temperature of drop falling, °C, it is not lower than 200 Penetration at 25 °C, 0,1 mm 280-360 Contents of mechanical impurity, % Absence Test for corrosion are not formed greens, tm-gray, brown or black spots Strength at 50 °C, Pa, not less than 120 Viscosity effective at -50 °C, Grazed, no more than 800 VNIINP-207 Lubricant in accordance with GOST 19774-74 mix of kremniyorganichesky liquid and synthetic hydrocarbonic oil, thickened complex soap; contains anti-oxidizing additive. VNIINP-207 lubricant the waterproof, hygroscopic, increased thermooxidizing stability, is efficient with a residual pressure of 666,5 Pas and temperature-60 … +200 °C. VNIINP-207 Lubricant in rolling bearings of electrical machines and a starter generators with a frequency of rotation up to 10000 min.-1 is applied.
