Angular contact ball bearings are a type of precision bearing designed to support combined radial and axial loads, as well as pure axial loads, in a specific direction. These bearings are engineered with raceways in the inner and outer rings that are designed to accommodate high-speed and high-precision applications, particularly in machinery and equipment where precise positioning and controlled motion are essential.

   - Spherical Roller Bearings: Spherical roller bearings are specifically engineered to accommodate misalignment, making them valuable in applications where shaft deflection or housing misalignment may occur. This feature allows them to maintain performance in challenging operating conditions.

   - Cylindrical Roller Bearings: Cylindrical roller bearings consist of cylindrical rollers that are guided by inner and outer ring raceways. They are designed to support high radial loads and moderate axial loads and are commonly used in applications where precise radial load support is essential.
