Solid lubricant for bearing

摘要

Solid lubricant for bearing comprises a mixture of 5-98 wt.% of a lubricating grease and 94-1 wt.% of a polyolefin powder with ultrahigh molecular weight, and a corrosion protection agent in the form of a sulphonate or a partial ester of a fatty acid with a multivalent alcohol. The mixture is heated to a temperature which is higher than the gelatinising point of the polyolefin with ultra-high molecular weight and lower than the dropping point of the lubricating grease. Also claimed are 3 alternative compositions
