ROLLING BEARING FOR HARD DISK DRIVE ACTUATOR, AND BEARING UNIT

摘要

PROBLEM TO BE SOLVED: To provide a rolling bearing for an HDD actuator minimizing outgassing and further enhancing durability and to provide a bearing unit. SOLUTION: In the rolling bearing for the HDD actuator which is to be incorporated in the actuator of the hard disk drive, a plurality of rolling bodies are held between an inner ring and an outer ring via a holder, and grease formed by compounding a diurea compound having at least one of an alicyclic hydrocarbon group and an aliphatic hydrocarbon group in its skeleton as a thickening agent into a base oil containing an aromatic ester oil is encapsulated. The bearing unit is formed by housing the rolling bearing for the HDD actuator into a housing. COPYRIGHT: (C)2006,JPO&NCIPI
