GREASE COMPOSITION, ANTIFRICTION BEARING, AND ELECTRIC MOTOR |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a grease composition excellent in fretting prevention performance, an antifriction bearing hardly allowing fretting to occur, and a long-life electric motor. SOLUTION: The grease composition comprises a base oil and a thickening agent. The base oil is a mixed base oil comprising a low-viscosity base oil having a kinematic viscosity at 40°C of 10-35 mm<SP>2</SP>/s and a high-viscosity base oil having a kinematic viscosity at 40°C of 50-120 mm<SP>2</SP>/s and has a kinematic viscosity at 40°C of 15-60 mm<SP>2</SP>/s.
