PROBLEM TO BE SOLVED: To provide a thrust ball bearing which is so constructed for a bearing disc of circular ring shape to have a high degree of endurance strength. SOLUTION: The thrust ball bearing (1) comprises a first and a second bearing discs (2, 3) of circular ring shape which a mutually located at a fixed spacing wherein the bearing disc moves eccentrically to each other, thereby bearing balls (4) arranged between the bearing discs are guided to roll on the assigned circular raceway surfaces (5). The bearing discs (2, 3) of circular ring shape are fabricated from ferrous material to which through hardening is applicable. |
