The lubricating composition of VNIINP-207 has found application in rolling bearings, which are components of starter generators and electric machines with a high rotation speed of up to 10,000 min-1. The lubricant formulation includes synthetic hydrocarbon oils and an organosilicon liquid. Also included is a thickener based on complex soaps and additives to enhance antioxidant properties.
Benefits
Externally, VNIINP 207 grease is a homogeneous composition of soft consistency from dark to light shades of brown. Distinctive physico-chemical and operational characteristics of the lubricant are:
- heat resistance;
- high stability to oxidative reactions;
- water resistance and hygroscopicity;
- working capacity in the range of -60 ... + 200 ° С at a residual pressure of 66.5 Pa.
Application area
VNIINP-207 heat-resistant grease is used for rolling bearings of electric machines and starter-generators with a rotation frequency of up to 10,000 min-1.
It is efficient at a residual pressure of 666.5 Pa in the temperature range from -60 ° C to + 200 ° C.
