ROLLING BEARING AND ITS PACKAGING METHOD

摘要

To provide a rolling bearing in which a favorable antirust performance can be obtained while reducing an amount of antirust oil than before, after removing chloride ions and sulfate ions from the entire surface of the bearing, antirust oil is provided to adhere thereto at an average film thickness of 4.5 μm to 10 μm, and the entire bearing is covered with a volatile corrosion inhibitor film such that a space between the volatile corrosion inhibitor film and the bearing is kept in a pressure-reduced condition.

主权项

1. A rolling bearing comprising an inner ring, an outer ring, and a plurality of rolling elements retained between the inner ring and the outer ring by a retainer in a rollable manner,
wherein antirust oil is provided to adhere, at an average film thickness of 4.5 μm to 10 μm, to an entire surface of the bearing from which chloride ions and sulfate ions are removed, the entire bearing is covered with a volatile corrosion inhibitor film, and a space between the volatile corrosion inhibitor film and the bearing is kept in a pressure-reduced condition.
