Why are deep groove ball bearings widely used?

As we all know, deep groove ball bearing is the most representative rolling bearing, and it is also the most widely used type of bearing in the field of mechanical equipment. So why are deep groove ball bearings widely used? Because it has many features, let's take a look at it together.

The characteristics of deep groove ball bearings are:

1. The structure of deep groove ball bearing is simple and easy to use.

2. Compared with other types of bearings with the same specifications and dimensions as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed.

3. The manufacturing cost is low, and it is easy to achieve high manufacturing precision, so it is convenient for mass production in series, and it is extremely common.

4. Deep groove ball bearings are mainly used to withstand radial loads, and can also withstand a certain amount of axial loads. Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery , construction machinery, etc.

5. In addition to the basic type, deep groove ball bearings also have various modified structures, with various sizes and forms. They can be used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery industries. They are used in the machinery industry. The most widespread type of bearing.

6. But when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear the combined radial and axial loads. It can also be used to bear pure axial load when the rotational speed is high and the thrust ball bearing is not suitable.

7. However, it is not resistant to impact and is not suitable to bear heavy loads.

The working principle of deep groove ball bearing:

Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial load, 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 bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also high.

There are various processing forms of deep groove ball bearing parts:

1. Multi-process processing: Generally, the production of bearings requires 20 to 40 processes, and there are more than 70 processes.

2. Forming processing: The working surfaces of bearing parts are all rotary forming surfaces, which are suitable for processing by forming method.

3. Precision machining: Most of the surface of the bearing parts must be ground, and the size and geometric accuracy of the grinding are in μm.

It can be seen that, because deep groove ball bearings have many advantages, various processing forms, and low manufacturing costs, deep groove ball bearings have now been widely used in the industry.
