Grease VNII NP-235
heat-resistant grease
Description
Lubrication VNIINP 235 according TU 38. 101297-78 silicone fluid, thickened with an organic thickener.
Applications
It is used rolling bearings. The viscosity of the lubricant VNIINP 235 slightly dependent on the deformation rate; high thermal and low colloidal stability, good extreme pressure properties. Efficient at a residual pressure of 666.5 Pa and a temperature of -60 … + 250 ° C. Substitute lubrication VNIINP-231.
