Grease composition preventing flaking

摘要

A grease composition comprising a lubricant base oil and a metal dithiocarbamate represented by the formula (1): <CHEM> wherein R<1> to R<4> may be the same or different and each stands for a hydrocarbon group having 10 to 20 carbon atoms, and X stands for a metal or a metal-containing group. The composition has long life even when used at a high temperature, is not harmful to humans and the environment, and can give an extended anti-flaking life to the rolling bearing.
