- Needle Roller Bearings: Needle roller bearings feature cylindrical rollers with a much smaller diameter-to-length ratio compared to cylindrical rollers. This design allows for a higher load-carrying capacity in a compact space, making needle roller bearings suitable for applications with limited radial space.

The deep groove design is particularly advantageous for radial loads, as it enables the bearing to support forces that act perpendicular to the shaft's axis. Additionally, the deep groove configuration allows the bearing to accommodate some degree of axial load, although axial load capacity is typically lower than radial load capacity in deep groove ball bearings.

The primary difference between a thrust ball bearing and a radial ball bearing lies in their design and the direction of the loads they are designed to support:
