- Spherical Roller Bearings: Spherical roller bearings are designed to primarily support heavy radial loads and moderate axial loads. Their unique design includes barrel-shaped rollers guided by inner and outer ring raceways with a common spherical raceway on the outer ring, allowing them to accommodate misalignment and axial displacement. They are commonly used in applications where heavy radial loads, shock loads, and misalignment are present, such as in heavy machinery, mining equipment, and industrial applications.

The angle of contact in angular contact ball bearings is a critical design parameter that influences the bearing's load-carrying capacity, precision, rigidity, and high-speed capability. It allows the bearing to operate efficiently under dynamic and oscillating loads, making it suitable for applications where precise motion control and accurate load distribution are essential.

   - Tapered Roller Bearing: Tapered roller bearings consist of tapered rollers and raceways, with the rollers and raceways designed to meet at a common point on the bearing axis. This design allows the bearing to support both radial and axial loads, as well as combinations of these loads, making them suitable for applications where precise motion control and high load-carrying capacity are essential.

The difference between angular contact and radial contact bearings lies in their design and intended applications:
