There are several types of quality ball bearing available, each with its unique characteristics and applications.

1. Deep Groove Ball Bearings - These are the most common type of ball bearings and are used in a wide range of applications. They have a simple design and can support radial and axial loads.

2. Angular Contact Ball Bearings - These bearings are designed to support axial loads in one direction and are commonly used in machine tools and pumps.

3. Thrust Ball Bearings - These bearings are designed to support axial loads in both directions and are commonly used in automotive applications.

4. Cylindrical Roller Bearings - These bearings are designed to support heavy radial loads and are commonly used in industrial applications.

5. Self-Aligning quality ball bearing - These bearings are designed to self-align, reducing the risk of misalignment and damage to the machinery.
