PROBLEM TO BE SOLVED: To provide a rolling bearing for an HDD actuator that uses a low vapor-pressure lubricant enhanced in the property of long-time lubrication, having low torque and little torque variation and capable of minimizing outgassing. SOLUTION: In the rolling bearing wherein a holder is interposed between an inner ring and an outer ring and a plurality of rolling bodies is held, synthetic lubricating oil, of which the vapor pressure at a temperature of 25 deg.C is less than 1.3×10-3 Pa, is put therein as a lubricant. |
