Angular contact ball bearings (ACBBs) are a type of rolling element bearing that are designed to handle both radial and axial loads. They have a contact angle between the balls and the raceways, which allows them to support axial loads in addition to radial loads. This design provides several advantages over other types of bearings. One of the main advantages of angular contact ball bearings is their ability to handle high axial loads. The contact angle between the balls and the raceways allows for a greater load capacity in the axial direction compared to other types of bearings. This makes ACBBs suitable for applications where there are heavy axial loads, such as in machine tools and automotive transmissions. Another advantage of ACBBs is their high stiffness. The contact angle of the bearings helps to distribute the load evenly across the balls and raceways, which reduces the deformation of the bearing under load. This results in a more rigid bearing that can maintain its shape an…
