Grease VNIINP – 207
aviation lubricant
Description
Grease VNII NP-207 of the same type of composition and properties of lubricated CIATIM-221. It is prepared in a mixture of polysiloxane fluid to the MAC-35 oil. This improves thermal oxidative stability of lubricants. Lubrication VNIINP-207 significantly superior grease CIATIM-221 on service life in the rolling bearings at 150-180 ° C.
Applications
Grease VNIINP – 207 is used in the rolling bearings of electric machines and starter-generators with a speed of up to 10,000 min-1
.
Advantages
- It contains antioxidant additive;
- Grease VNII NP-207 offers exceptional water resistance, water absorption, enhanced thermal oxidative stability;
- VNIINP-207 – is operable at a residual pressure of 666.5 Pa and a temperature of -60 … + 200 ° C;
- replacer VNIINP lubricant grease-207 Ciatim-221 (up to + 150 ° C).
