Plane thrust bearing loose ring installation method

Plane thrust bearings are mainly subjected to axial loads in the assembly and are widely used. Although the thrust bearing installation operation is relatively simple, but the actual maintenance is still often errors occur, that is, the bearing ring and loose ring installation position is not correct, the result of the bearing is lost, the journal quickly wear. The inner ring of the tight ring is in transition with the journal. When the shaft rotates, the tight ring is brought into motion and friction occurs with the end surface of the stationary part. When subjected to the axial force (Fx), the friction moment larger than the inner diameter is combined with the resistance torque, resulting in tightness. Forced rotation of the ring and shaft mating surfaces intensifies wear of the journal.
     Therefore, the thrust bearing installation should pay attention to the following points.
     (1) Distinguish the tight ring and loose ring of the bearing (according to the size of the bearing inner diameter, the difference in the hole diameter is O.1 to O.5mm).
     (2) Distinguish the stationary parts of the mechanism (ie parts that do not move, mainly assembly).
     (3) In any case, the loose ring of the bearing should always be against the end face of the stationary part.
