What applications are 6900 series deep groove ball bearings commonly used for?

6900 series deep groove ball bearings are widely used for their low friction and high speed stability, whether it is a small DC motor in household appliances or a large AC motor for industrial use, to ensure the efficiency and quietness of the motor during operation. In the fields of renewable energy such as wind power generation and hydropower generation, as well as in traditional thermal power plants, this series of bearings is used for the rotating parts of the generator set, bearing huge radial and axial loads to ensure the continuous and stable operation of the power generation system.
From the engine crankshaft, gearbox to wheel bearings, the 6900 series bearings ensure the safety and comfort of the car under various extreme conditions with their high precision and durability. Motorcycles, electric bicycles and bicycles use this series of bearings to reduce the friction of rotating parts and improve the riding experience. Although more special bearings are used, 6900 series bearings can also be seen in the auxiliary transmission systems of some light rails and subways.
Tractors, harvesters, seeders, etc. use 6900 series bearings to improve the rotation efficiency of mechanical parts and reduce energy consumption. Mixers, cutting machines, packaging machines, etc. The corrosion resistance and easy cleaning characteristics of this series of bearings make it particularly important in food processing environments.
High-speed textile machines, such as spinning machines and looms, rely on the precise matching of 6900 series bearings to ensure the accurate transmission of yarn or cloth. In industries such as papermaking, printing, and plastic processing, this series of bearings is used for drive shafts, rollers, etc. to improve production efficiency.
Such as laser printers, scanners, precision measuring instruments, etc., the small size and high precision of 6900 series bearings ensure the precise operation of these devices. In high-tech production lines such as semiconductor manufacturing and electronic assembly, this series of bearings is used for robot arms, conveyor belts, etc. to support efficient production.
For roller skates and scooters, 6900 series bearings provide a smooth and unobstructed rolling experience. Carousels and Ferris wheels in amusement parks, etc., this series of bearings ensure the safe operation of large amusement facilities.
Heavy equipment such as excavators, cranes, and rollers use 6900 series bearings to support heavy loads and improve operating efficiency. Although specially designed bearings are more commonly used, this series of bearings can also be found in some auxiliary systems, such as ground testing equipment.
