The 6308 bearing is the most representative rolling bearing with a wide range of applications. They are suitable for operation at high or even very high speeds and are extremely durable, requiring no frequent maintenance. These bearings have a low coefficient of friction, high limiting speeds, simple construction, low manufacturing costs and high manufacturing accuracy. Size range and form of change in a variety of applications in precision instruments, low noise motor, automotive, motorbike and general machinery and other industries, is the most widely used in the machinery industry in a class of bearings. Mainly bear radial load, but also can bear a certain amount of axial load.
