8mm thrust bearings are composed of two thrust gaskets and rolling bodies

8mm thrust bearings are composed of two thrust gaskets or more thrust gaskets and a number of rolling bodies. Generally, thrust gaskets are divided into shaft plates and seat plates.The most common type of rolling bodies is generally composed of iron or copper cages.  
8mm thrust bearings is mainly subjected to axial load in assembly and is widely used. Although the installation and operation of 8mm thrust bearings are relatively simple, errors often occur in actual maintenance, that is, the installation position of the tight ring and loose ring of the bearings is not correct, which results in the loss of the bearing and the journal is quickly worn out.  

The tight ring is installed on the end face of the stationary part, that is, wrong assembly.The inner ring of the tight ring is a transition fit with the shaft journal. When the shaft rotates, the tight ring is driven and friction occurs with the end face of the stationary part.
When the axial force (Fx) is applied, the friction torque is greater than the resistance moment of the inner diameter fit, resulting in forced rotation of the tight ring and the shaft mating surface, which intensifies the wear of the shaft journal.  

The following points should be paid attention to when installing 8mm thrust bearings.  
(1) distinguish the tight ring and loose ring of the 8mm thrust bearings (according to the size of the inner diameter of the bearing, the aperture difference is O.1~O.5mm).  
(2) distinguish the static parts of the mechanism (that is, the parts that do not move, mainly refers to the assembly).  
(3) No matter what the case, the loose ring of the 8mm thrust bearings should always be on the end face of the stationary part.
