Which type of bearing is capable of withstanding axial loads from either direction?

The double row angular contact bearing is designed specifically to handle both axial loads and radial loads from either direction. This is due to its unique geometry, which features two rows of rolling elements arranged in a way that allows for tight contact angles. This design helps distribute the load effectively, enabling it to support significant axial forces in both directions.

In applications where axial loads must be managed from either direction, the double row angular contact bearing excels because it can absorb these forces without compromising its integrity or performance. Additionally, it is also more rigid compared to other bearing types, making it suitable for high-load applications.

Other types of bearings, like the single row ball bearing or the deep groove ball bearing, may only be effective for axial loads in one direction, depending on their design and arrangement. The self-aligning ball bearing, while it can accommodate some misalignment, does not have the same capacity for handling axial loads from both directions as effectively as the double row angular contact bearing does. Therefore, the ability to withstand axial loads from either direction is a defining feature of the double row angular contact bearing, making it the correct choice in this scenario.
