Rolling bearing and its manufacturing method |
| abstract |
To provide a rolling bearing having excellent acoustic properties and durability, which is preferable for applications requiring excellent anti-oiling effect, and low amount of lubricant or low torque of a bearing using a low viscosity lubricant. To this end, the present invention provides a rolling element comprising an alumina component and an yttria-zirconia component containing 1.5 to 5 mol% of a zirconia component or yttria in a mass ratio of an alumina component: a zirconia component or an yttria-zirconia component = 5 to It is made from the alumina-zirconia-based composite material which contains 50: 50-95. |
