VNII NP–207
GOST 19774-74
It is a blend of organic-silicon fluid and synthetic hydrocarbon oil thickened with complex soap. It also contains antioxidant additive. The thermostable lubricant is used in electric machinery frictionless bearings and starter-generators with rotational speed up to 10 000 min-1. The lubricant works at residual pressure 666.5 Pa in the temperature range from – 60oC to + 200oC.
