ABSTRACT:
According to the invention, a self contained vibration resistant bearing is provided. The bearing is coated with a film formed from a rust preventive oil having an extreme-pressure additive content of 0.5 to 10% by weight. Desirably the extreme-pressure additive is an organometallic compound, an organofatty acid compound, organofatty acid derivative, an organophosphoric acid compound or a combination of two(2) or more of such compounds. When a rust preventive film that contains an extreme-pressure additive is formed all over bearing components during the assembling process, the bearing components are fully protected even from sudden vibrations from transportation.
