PROBLEM TO BE SOLVED: To suppress decrease in the acoustic properties of an alumina-zirconia rolling element at a high temperature and impart durability enough to withstand a high temperature around 100°C.SOLUTION: A rolling support device is made of ceramic using alumina-zirconia as the main component, comprising sintered particles with an average particle diameter of 0.5 μm or less, with the monoclinic amount of 10% or less. |
