Grease composition, rolling device and rolling bearing |
| abstract |
The present invention provides a grease composition having a high effect of reducing fretting wear even when vibration is large, and a rolling device and a rolling bearing that are more excellent in fretting resistance and more durable. A rolling device comprising a grease composition containing a base oil having a pressure viscosity coefficient of 25 GPa-1 or more at 40 ° C. and iron sulfide fine particles having an average particle diameter of 1 to 20 nm. Even when the amplitude ratio of the rolling bearing is small, the effect of reducing fretting wear can be enhanced, and a rolling device and a rolling bearing having excellent fretting resistance and excellent durability can be provided.
