The 6900 Series Deep Groove Ball Bearing is a precision bearing with an inner diameter of 10mm, an outer diameter of 22mm and a thickness of 6mm. This bearing is widely used in motors, water pumps, power tools, air compressors, household appliances and other equipment, and is favored for its strong load-bearing capacity and stable operation. At the same time, the 6900 series bearings require high production precision and are suitable for high-speed rotation and bearing certain radial loads. They are indispensable key components in many mechanical equipment.
