The term angle of contact in the context of ball bearings refers to the angle formed between the direction of the load and a line perpendicular to the bearing axis. In the case of angular contact ball bearings, this angle is specifically designed to optimize the bearing's ability to support combined radial and axial loads, as well as pure axial loads in a specific direction.

   - Spherical Roller Bearings: Spherical roller bearings are well-suited for applications where heavy radial loads, shock loads, and moderate axial loads are present, and where misalignment accommodation is required.

The angle of contact in angular contact ball bearings is carefully engineered to ensure that the bearing can effectively distribute and support the applied loads. By adjusting the angle of contact, the bearing can be optimized to handle varying degrees of radial and axial loads, providing versatility and adaptability for different applications.
