What does axial positioning mean?

[DiWeston]

Axial positioning means: In order to prevent the bearing from moving axially when subjected to axial load, axial positioning devices should be applied to both the bearing on the shaft and the outer Nanning hole. The choice of positioning method for the bearing on the shaft and in the housing hole depends on the magnitude and direction of the load acting on the shaft, the rotational speed of the bearing, the type of bearing, and the position of the bearing on the shaft. Generally, axial positioning uses a shaft shoulder to position the inner ring, and the outer ring is positioned by the shoulder of the bearing seat hole or the retaining ring. To ensure the positioning effect of the shaft shoulder and the retaining shoulder, the shaft shoulder and the retaining shoulder should be tightly fitted to the end faces of the inner and outer rings of the bearing. The height of the shaft shoulder and the retaining shoulder should also be selected according to standards, which can ensure positioning strength and facilitate installation and disassembly.
