- Radial contact bearings, also known as deep groove ball bearings, are designed primarily to support radial loads, which are forces acting perpendicular to the shaft's axis.

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.
