deep groove ball bearing 6309

The inner diameter of 6309 is 45mm, the outer diameter is 100mm, and the thickness is 25mm. It belongs to the open expansion compensation bearing. The bearing is the most representative rolling bearing and has a wide range of uses. It is suitable for high-speed and even extremely high-speed operation, and it is very durable and does not require frequent maintenance. This type of bearing has a small friction coefficient, high limit speed, simple structure, low manufacturing cost, and easy to achieve high manufacturing precision. The size range and form vary, and they are used in precision instruments, low-noise motors, automobiles, motorcycles, general machinery, and other industries. They are the most widely used type of bearings in the machinery industry. It mainly bears the radial load, and can also bear a certain amount of axial load. It can be used for environmental protection and energy-saving equipment, fan coil units, eyebrow washing machines, hot presses, automobiles, packaging testing machines, multi-functional separate hydraulic tools, multi-way valves, stacker lifting platforms, vacuum generators, window rails, Curtain rods. Installation method of deep groove ball bearing: By heating the bearing or bearing seat, the installation method of changing the tight fit to the loose fit by thermal expansion. It is a common and labor-saving installation method. This method is suitable for large interference. For the installation of the bearing, put the bearing or separable bearing ring into the oil tank and heat it evenly at 80-100 ℃ before hot-loading, and then take it out of the oil and install it on the shaft as soon as possible. If the bearing is not tightly closed, the bearing can be axially tightened again after cooling. When the outer ring of the bearing is tightly fitted with the light metal bearing seat, the hot-fitting method of heating the bearing seat can be used to avoid the mating surface from being scratched. When heating the bearing with the oil tank, there should be a mesh grid at a certain distance from the bottom of the box, or hang the bearing with a hook. The bearing should not be placed on the bottom of the box to prevent heavy impurities from entering the bearing or uneven heating. There must be a thermometer in the oil tank. Strictly control the oil temperature not to exceed 100 ℃ to prevent the tempering effect and reduce the hardness of the ferrule.
