Abstract

The rust preventive lubricating oil of the present invention concerns a base oil and a rust-preventive agent in an amount of 2-20% by weight on the basis of the whole rust preventive lubricating oil, wherein the base oil contains an ether oil in an amount of at least 20% by weight on the basis of the whole rust preventive lubricating oil. The rust preventive lubricating oil can be applied to the surface of raceway tracks of inner and outer rings, cages for bearings, as well as to bearings, to prevent development of rust, to inhibit generation of cage sound, and to obtain good lubricity, while retaining good compatibility with a grease to be later charged.
