In summary, the key difference between spherical roller bearings and cylindrical roller bearings lies in their design, load-carrying capabilities, and suitability for specific applications. Each type of bearing is tailored to meet distinct operational requirements and environmental conditions in diverse industrial applications.

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.
