Spherical roller bearings and cylindrical roller bearings are both important types of rolling-element bearings, each with distinct design features and applications. Here are the key differences between the two:

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.

   - Cylindrical Roller Bearings: Cylindrical roller bearings are optimized for high radial load-carrying capacity and are suitable for applications where precise radial load support is required, such as in electric motors, pumps, and gearboxes. They are less effective in accommodating misalignment compared to spherical roller bearings.
