Ceramic thrust ball bearing 51104 mainly bears axial loads during use and is widely used. Although the installation method of flat thrust ball bearings is relatively simple, problems often occur during actual maintenance operations, the most common of which is the incorrect installation position of the tight and loose rings of the bearing, resulting in abnormal operation of the bearing and quick damage to the shaft neck. The following figure shows the installation of the tightening ring on the end face of the stationary part, which is an incorrect assembly. The inner ring of the tight ring is a transitional fit with the shaft neck. When the shaft rotates, it will drive the tight ring and rub against the end face of the stationary part. When subjected to axial force (Fx), the friction torque will be greater than the inner diameter fitting resistance torque, causing the tight ring and the shaft fitting surface to forcibly rotate, exacerbating the wear of the shaft neck.
