ABSTRACT:
A supporting pivot thrust bearing apparatus is provided in which a steel ball groove is formed at both ends of a rotary shaft inserted into a through hole of a sleeve, and a steel ball is fixably inserted between the steel ball groove and a thrust support. The steel ball is in contact with the steel ball groove by line contact so that lateral of the steel ball can be prevented. As a result, eccentricity between a center shaft of the steel ball and a center shaft of the rotary shaft can be prevented, thereby improving rotative stabilization of the rotary shaft.
