Deep Groove Ball Bearing
Deep groove ball bearings are the most widely used and high-yield category of rolling bearings. Their structure is simple and compact, and they can withstand both radial and bidirectional axial loads simultaneously. They have the core advantages of high speed, low noise, and easy maintenance, and are known as the key components of industrial transmission systems; Universal Transmission Foundation” , covering full scene adaptation from micro electronic devices to large industrial machinery
