[0002] Miniature bearings refer to various types of bearings with an outer diameter of less than 9mm in the metric series or less than 9.525mm in the imperial series. The main materials are carbon steel, bearing steel, stainless steel, plastic, ceramic, etc. At present, the world's smallest commercial steel ball bearing can achieve an outer diameter of 1.5mm, an inner diameter of 0.5mm, and a steel ball diameter of 0.25mm. Miniature bearings are mainly suitable for various industrial equipment, small rotary motors and other high-speed and low-noise fields, such as: office equipment, micro motors, instruments, small clocks, dental drills, hard disk motors, toy models and other related fields.
