- Spherical Roller Bearings: Spherical roller bearings have barrel-shaped rollers that are guided by inner and outer ring raceways with a common spherical raceway on the outer ring. This design allows the bearing to accommodate misalignment and axial displacement, making them suitable for applications where shaft deflection or misalignment is present.

   - Angular contact bearings are designed to support combined radial and axial loads, as well as pure axial loads in a specific direction.

The deep groove in a ball bearing is a fundamental design feature that enables the bearing to provide smooth and reliable operation, reduce friction, and support loads in a variety of mechanical systems. Its ability to accommodate radial and axial loads while maintaining efficient rotation makes deep groove ball bearings essential components in many types of machinery and equipment.
