VNIINP-219 lubricant according to TU 38.101471-74 is close to VNIINP-207 lubricant, but in contrast to it contains molybdenum disulfide. VNIINP-219 grease is efficient at a temperature of -50 ... + 200 ° С.
Application area
VNIINP-219 grease lubricates the rolling bearings of electric motors and starter generators with increased loads and a rotation speed of up to 9000 rpm, ball-screw gears of aircraft. It is efficient at a temperature of -50 ... + 200 ° С. VNIINP-219 grease is similar in composition to VNIINP-207 grease, but unlike it contains molybdenum disulfide.
