VNIINP - 235 grease (TU 38. 101297-78) is an organosilicon fluid thickened with an organic thickener.
Application area
It is used in rolling bearings. The viscosity of the lubricant is slightly dependent on the strain rate; high thermal and low colloidal stability, good extreme pressure properties. It is efficient at a residual pressure of 666.5 Pa and a temperature of -60 ... + 250 ° C.
Substitutes: VNIINP-231.
