VNIINP-247 grease according to TU 38.401352-81 is similar in composition to VNIINP-207 grease. It is characterized by low hygroscopicity and thermal hardening. It is efficient at a temperature of -40 ... + 180 ° С.
The main purpose of lubricants is to reduce the wear of friction surfaces to extend the service life of machine parts and mechanisms. Along with this, lubricants perform other functions. In some cases, they do not so much reduce wear as they streamline it, preventing scoring, jamming and jamming of friction surfaces. Lubricants prevent the penetration of aggressive liquids, gases and vapors, as well as abrasive particles (dust, dirt, etc.) to the friction surfaces.
Application area
Bearing units of low-power and microelectric machines with a rotation speed of up to 20,000 rpm, gear drives of electric fans.
