How do deep groove ball bearings bear axial load?

As a common and important type of rolling bearing, the design and structure of deep groove ball bearings are mainly focused on bearing radial loads. However, their design also takes into account the ability to adapt to axial loads under certain circumstances. Understanding how deep groove ball bearings carry loads in the axial direction involves a range of engineering and design principles.

The design structure of deep groove ball bearings is relatively simple, consisting of an inner ring, an outer ring, steel balls and a cage. This simple and effective structure makes the bearing more stable and reliable during manufacturing and use. In terms of bearing axial load, the designer fully considered the angle of the ball and cage to make it have certain adaptability in the axial direction. This means that in some applications, deep groove ball bearings can adjust and distribute axial forces through their internal design.

The design of the inner and outer rings also affects the performance of deep groove ball bearings in the axial direction. Their geometry and relative position determine how axial loads are distributed and transmitted. By rationally designing the inner and outer rings, the axial load bearing capacity can be optimized.

In some designs, deep groove ball bearings adopt a preload design to improve their ability to withstand axial loads by preloading the bearings. Preload is usually achieved by adjusting the relative position of the inner and outer rings or using springs and other devices. This design allows the bearing to better cope with additional forces in the axial direction.

However, it needs to be clear that the axial load carrying capacity of deep groove ball bearings is relatively limited. For applications that are primarily subject to axial loads, you may want to consider using a bearing type specifically designed to handle axial loads, such as a thrust ball bearing. This specialized bearing is more able to withstand large axial loads more effectively.
