Deep groove ball bearings are a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. They are versatile and can handle both radial and axial loads, making them suitable for a wide range of applications. However, when it comes to thrust loads, the performance of deep groove ball bearings is somewhat limited compared to other types of bearings designed specifically for thrust loading.
The ability of a deep groove ball bearing to withstand thrust loads depends on several factors, including its design, size, and the arrangement of the balls within the bearing. In a standard deep groove ball bearing, the maximum thrust load that can be supported is typically one-third to one-half of the bearing's radial load capacity. This is because the contact angle between the balls and the races is shallow, which limits the ability of the bearing to support axial forces without causing excessive wear or potential failure.
To enhance the thrust load capacity of deep groove ball bearings, manufacturers often offer bearings with a larger contact angle or modified designs, such as adding a flange on one of the races. These modifications can increase the contact area between the balls and races under axial loading, improving the bearing's ability to handle thrust loads These modifications can increase the contact area between the balls and races under axial loading, improving the bearing's ability to handle thrust loads

Despite these enhancements, for applications where significant thrust loads are expected, it may be more appropriate to use specialized thrust bearings, such as tapered roller bearings or dedicated thrust ball bearings. These bearings are designed with features optimized for thrust loads, such as steeper contact angles, larger rolling elements, and improved race geometries, ensuring better load distribution and longer service life under axial forces.
In conclusion, while deep groove ball bearings can accommodate some degree of thrust load, their primary strength lies in handling radial loads. For applications requiring substantial thrust capacity, engineers should consider using bearings specifically designed for this purpose or adapting deep groove ball bearings with enhanced features for improved axial load support. Proper selection and configuration of bearings are crucial for ensuring the reliability and efficiency of mechanical systems subjected to complex loading conditions.
