The primary difference between a tapered roller bearing and a ball bearing lies in their design and load-carrying capabilities:

A deep groove in a ball bearing refers to the specific design feature of the bearing's inner and outer raceways, which allows it to accommodate radial and axial loads while enabling smooth and efficient rotation. The deep groove is a critical aspect of the ball bearing's construction and contributes to its performance in various applications.

   - Spherical Roller Bearings: Spherical roller bearings are well-suited for applications where misalignment, heavy radial loads, and moderate axial loads are present. Their ability to accommodate misalignment makes them valuable in applications where shaft deflection or housing misalignment may occur.
