Disclosed is a lubricant for oil retaining bearings which contains 1-100% by mass of an ion liquid. This lubricant for oil retaining bearings has a low vapor pressure while being at low risk of inflammability. In addition, this lubricant is excellent in heat resistance and suppressed in generation of a low volatile component or a decomposed gas during use. Alternatively, the lubricant for oil retaining bearings may have antistatic properties and is capable of grounding static charges generated by streaming electrification. |
