VNII NP-207 from Own Production
Grease "BORA B" VNII NP-207
Product Description:
Grease VNII NP-207 is close in its composition and properties to the BORA B grease Ciatim-221. However, it significantly exceeds it in terms of service life in rolling bearings at a temperature of 150-180°C. Our experts have solved the problem of the tendency of this grease to heat and moisture sealing in comparison with the grease VNII NP-207, produced in accordance with GOST 19774-74. The grease has increased thermal oxidative stability and maintains its working capacity at a residual pressure of 666.5 Pa. It has an extended service life, and, as a result, increases the service life of bearings in production units, as well as in units of agricultural machines.
Application:
Grease VNII NP-207 is used in rolling bearings of electric machines and starter-generators with a rotation frequency of up to 10,000 rpm. Use at ambient temperature from - 50°C to + 180°C.
