In bicycle accessories, bearings are usually hidden inside the parts and easily overlooked, but they are crucial rotating components that provide flexible steering for bicycles. Bicycle bearings are installed in components such as flower drum bearings, five way bearings, directional bearings, pedal bearings, transmission bearings, etc. Basically, every part that needs to be moved will have a bearing.

Deep groove ball bearings require high precision in operation, but with the development of manufacturing technology, the tolerance difference of parts such as flower drums and frames is becoming smaller and smaller, and deep groove ball bearings are being used more and more.
