The bearing load of deep groove ball bearing is too small during operation, which will cause sliding between the ball and the raceway and become the cause of scratch. In particular, large deep groove ball bearings with heavy ball and cage have this tendency. In many cases, bearing corrosion will occur, and there are many reasons for bearing corrosion. The most common factors in our daily life are the following:
1) Due to poor sealing device, it is invaded by moisture, dirt, etc;
2) The bearing is not used for a long time, which exceeds the rust proof period and lacks maintenance.
3) The surface roughness of metal is large;
4) Contact with corrosive chemical media, the bearing is not cleaned cleanly, there is dirt on the surface, or contact the bearing with sweat hands, the bearing is not packed or installed in time after cleaning, and is exposed to the air for a long time, which is invaded and contaminated by air moisture;
5) Ambient temperature and humidity and exposure to various environmental media; The antirust agent is invalid or the quality does not meet the requirements.

We have a wide variety of deep groove ball bearings. Deep groove ball bearing is also the most common type of bearing, but it is widely used in many fields.
Bearing construction
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 in large quantities, with low manufacturing costs and are widely used. In addition to the basic type, deep groove ball bearings also have various variant structures, such as: deep groove ball bearings with dust covers, deep groove ball bearings with rubber seals, deep groove ball bearings with stop grooves, deep groove ball bearings with large load capacity with ball loading gaps, and double row deep groove ball bearings.

Processing form
The processing form of deep groove ball bearing parts is as follows:
- 1. Multi process processing: generally, bearing production requires 20 ~ 40 processes, with 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 surfaces of bearing parts need to be ground, and the grinding dimension and geometric accuracy are based on μ M is the unit.
According to the size of deep groove ball bearings, they can be divided into:
- Miniature bearing —- bearing with nominal outer diameter less than 26mm;
- Small bearings —- bearings with a nominal outer diameter of 28-55mm;
- Small and medium-sized bearings —- bearings with a nominal outer diameter of 60-115mm;
- Medium and large bearings —- bearings with nominal outer diameter ranging from 120 to 190mm
- Large bearing —- bearing with nominal outer diameter ranging from 200 to 430mm;
- Oversize bearing —- bearing with a nominal outer diameter of more than 440mm.
Deep groove ball bearing Application
Deep groove ball bearings can be used in gearboxes, instruments and meters, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo yos, etc
