Angular contact ball bearings are a type of high-precision rolling bearing composed of an inner ring, an outer ring, a cage, and steel balls. The inner and outer rings of angular contact ball bearings are both arc-shaped, and their geometric centers do not coincide, giving the bearing the characteristic of contact angle. The steel balls are placed between the inner and outer rings and are arranged equidistantly through the cage. When subjected to loads, the steel balls can roll freely, allowing the bearing to withstand loads and moments in multiple directions. Additionally, the free rolling of the steel balls results in relatively low friction and noise.

The seals of angular contact ball bearings can prevent dust and water, maintain lubricating oil inside the bearing, and prevent external impurities from entering. This can prolong the service life of the bearing and improve its performance.
