A pair of circular grooves are formed on the front surface of the shaft ring. A limiting slot is formed on the back surface of each circular groove. The limiting slot is of a rectangular structure. A pair of threaded through holes are formed on the back surface of the housing ring. A self-lubricating locking component is threadedly connected to each threaded through hole.

[0003] During the use of the self-lubricating thrust ball bearing in this patent application, by using a T-shaped block to be clamped in the circular groove with a limiting slot, the rolling elements, the shaft ring and the housing ring are tightly combined and installed together. However, during such use, since the thrust ball bearing bears a large load during operation, and only two sets of T-shaped block structures are provided for connecting the upper and lower ends of the rolling elements, the shaft ring and the housing ring, and there is a lack of connection structures at the other positions except the upper and lower ends among the rolling elements, the shaft ring and the housing ring, resulting in the overall structural stability of the thrust ball bearing being reduced and the practicability of the device being reduced. For this reason, we propose an extra-large thrust ball bearing. Summary of the Utility Model
