Deep groove ball bearings are the most representative rolling bearings, and they are widely used. Used for high-speed and extremely high-speed work, it is very durable and does not require frequent maintenance. Deep groove ball bearings have low friction coefficient, high limit rotation speed, simple structure, low manufacturing cost, and high manufacturing accuracy. The range of sizes and structure types vary widely. They are widely used in industries such as precision instruments, low-noise motors, various automobiles, motorcycles, and common machinery. They are the most widely used type of bearings in the machinery industry. Usually can withstand radial load, it may also withstand a certain amount of axial load.
Deep groove ball bearings are frequently selected rolling bearings. The structure of deep groove ball bearings is simple and easy to use. It is usually used to bear radial load, but when the radial clearance of the bearing is increased, there is a certain function of angular contact ball bearing, and it can also bear the combined radial and axial load. When the rotation speed is high and it is not suitable to choose the thrust ball bearing, it is also used to withstand pure axial load. Compared with other types of bearings with similar specifications and dimensions of deep groove ball bearings, this type of bearing has a low friction coefficient and a high limit rotation speed. However, it is not resistant to impact and is not suitable for being able to withstand heavy loads.
When a larger radial clearance is selected, the axial bearing force is increased, and the contact angle is zero when the pure radial force can be bear. When the axial force is used, the contact angle is greater than zero. Under common conditions, stamping wave-shaped cages and car-made solid cages are selected. In some cases, nylon cages are also selected.
The deep groove ball bearing is installed on the shaft and then, within the range of the axial clearance of the bearing, the axial displacement of the shaft or the housing can be limited, so it can be axially positioned in both directions. It is worth mentioning that deep groove ball bearings also have a certain degree of self-aligning ability. When they are inclined 2'~10' relative to the housing hole, they can still work normally, but it will have a certain impact on the life of the bearing. Deep groove ball bearing cages are mostly stamped steel plate corrugated cages (steel cages in deep groove ball bearings are represented by the English letter J), and large bearings mostly choose car-made metal solid cages.
