Deep groove ball bearing, originally listed as centripetal ball bearing, is one of the most widely used rolling bearings. It is characterized by low friction resistance and high speed. It can be used on the parts bearing both radial load and radial and axial load. It can also be used on the parts bearing axial load, such as low-power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines and tools.
The working principle of deep groove ball bearing mainly bears radial load, but also can bear both radial load and axial load. When it only bears radial load, the contact angle is zero. When deep groove ball bearings have large radial clearance, they have angular contact bearing performance, can withstand large axial loads, the friction coefficient of deep groove ball bearings is very small, and the ultimate speed is also high. Deep groove ball bearings are mainly used to withstand radial loads, but they are also often used to withstand combined radial and axial loads. Especially when the rotating speed of mechanical equipment is very high and thrust bearing is not suitable for use, it can be used to withstand bidirectional pure axial load without maintenance during working. It is a kind of bearing with low price and wide use. Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, roller skates, yo-yo, etc.
Deep groove ball bearings are simple in structure and easy to achieve higher manufacturing accuracy compared with other types, so they are easy to be produced in series and in large quantities, and have lower manufacturing costs and are widely used. When the radial clearance is larger, the axial bearing capacity increases, and the contact angle is zero when the pure radial force is applied. When the axial force is applied, the contact angle is greater than zero. In addition to the basic type, deep groove ball bearings also have various variant structures, such as deep groove ball bearings with dust cover, deep groove ball bearings with rubber sealing ring, deep groove ball bearings with stop grooves, deep groove ball bearings with large load capacity with ball notches, double row deep groove ball bearings. Each ring of deep groove ball bearing has a continuous Groove Raceway whose cross section is about one third of the circumference of the ball. It is mainly used to bear radial loads, but also can bear certain axial loads. 2. When the radial clearance of the bearing increases, it has the property of angular contact ball bearing, which can bear the axial loads alternating in two directions. 3. Friction. Small, high speed; 4. Simple structure, low manufacturing cost, equal leisure to achieve higher manufacturing accuracy;
