Abstract: PROBLEM TO BE SOLVED: To secure the excellent rolling service life, and maintain density small by forming at least either of a bearing ring and a rolling body out of ceramics having the composition by adding zirconia by a specific quantity to alumina.
SOLUTION: When zirconia is added to alumina as ceramics used for either of a bearing ring and a rolling body, a grain boundary of alumina is strengthened, strength is increased, and the rolling service life is also lengthened. It is necessary to add zirconia by at least 5 wt.% or more therefor. However, since the rolling service life is shortened when an adding quantity of zirconia too much, it is necessary to set a zirconia adding quantity not more than 50 wt.%. When the adding quantity of zirconia is not more than 50 wt.%, density of zirconia-added alumina can be maintained small as illustrated to thereby restrain an increase in a rolling body load by centrifugal force generated when the rolling body rotates at a high speed.
