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.

   - Needle Roller Bearings: Needle roller bearings are commonly used in applications where space is limited, and high radial load-carrying capacity is essential. They are often found in automotive, aerospace, and industrial applications where compact and lightweight bearing solutions are required.
