Deep groove ball bearing working principle and characteristics - Ball Bearing


The original list of deep groove ball bearings is a radial ball bearing and is the most widely used type of rolling bearing. It is characterized by low frictional resistance and high rotational speed. 


It can be used on parts with radial load or combined load of radial and axial action. It can also be used on parts with axial load, such as small power motors. Automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.


Deep groove ball bearings work mainly with radial loads and can also withstand radial loads and axial loads. When it is only subjected to radial loads, the contact angle is zero. 


When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed. 


Deep groove ball bearings are primarily used to withstand radial loads, but are also commonly used to withstand combined radial and axial loads. In particular, the mechanical equipment has a high rotational speed. 


When a thrust bearing is not suitable, the bearing can be used to withstand two-way pure axial load and requires no maintenance during operation.

It is a kind of bearing with low price and wide application. Deep groove ball bearings can be used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo, etc.


The deep groove ball bearing has a simple structure and is easy to achieve high manufacturing precision compared with other types, so it is easy to be mass-produced in series; the manufacturing cost is also low, and the use is extremely common. 


When the radial clearance is selected, the axial load capacity is increased, and the contact angle is zero when subjected to pure radial force. When the axial force is applied, the contact angle is greater than zero. 


Generally, the stamping wave cage is used, the solid cage is made of car, and the nylon frame is sometimes used. In addition to the basic type, the deep groove ball bearing has various modified structures, such as: deep groove ball bearing with dust cover; with rubber Deep groove ball bearings with sealing rings; deep groove ball bearings with snap grooves; deep groove ball bearings with large load capacity with ball gap; double row deep groove ball bearings. 


But they all have the following common features: Each ferrule of the structural deep groove ball bearing has a continuous groove type raceway having a cross section of about one third of the circumference of the ball. 


It is mainly used for bearing radial load and also bearing a certain axial load; 

2. When the radial clearance of the bearing increases, it has the property of angular contact ball bearing, which can bear the axial load alternating in two directions; 

3. The friction is small and the rotation speed is high; 

4. The structure is simple and the manufacturing cost is low. Equally achieve high manufacturing precision;
