- Spherical Roller Bearings: Spherical roller bearings have barrel-shaped rolling elements (spherical rollers) that are positioned between an inner ring with two raceways and an outer ring with a common spherical raceway. This design allows the bearing to accommodate misalignment and axial displacement.

   - The design of thrust ball bearings enables them to accommodate high axial loads and provide precise axial motion control.

In summary, roller bearings are used in a diverse range of applications across various industries, where their ability to support radial and axial loads, provide high load-carrying capacity, and withstand demanding conditions is essential.

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.
