PURPOSE: A thrust ball bearing is provided to obtain a bearing disc of circular ring shape having a high degree of endurance strength. CONSTITUTION: A thrust ball bearing(1) comprises a first and a second bearing discs(2,3) of circular ring shape which are 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). Since the bearing discs of circular ring shape are fabricated from ferrous material to which through hardening is applicable, a high degree of endurance strength is accomplished. |
