61800 zz Deep Groove Ball Bearing

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.

Characteristics of deep groove ball bearing:

Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has certain performance of angular contact ball bearing and can bear the combined radial and axial load. When the rotating speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same specification and size of deep groove ball bearings, this kind of bearing has small friction coefficient and high limit speed. But it is not resistant to impact and is not suitable to bear heavy loads.

After the deep groove ball bearing is installed on the shaft, the axial displacement in both directions of the shaft or housing can be limited within the axial clearance of the bearing, so it can be positioned axially in both directions. In addition, this kind of bearing also has a certain centering ability. When it is inclined by 2 ′～ 10 ′ relative to the shell hole, it can still work normally, but it has a certain impact on the service life of the bearing

Full ball bearing
Due to the design of the ball filling openings on the inner ring and outer ring, more balls can be loaded than deep groove ball bearings. Because it has a filling port, it is not suitable for applications with large axial loads. BL2 and BL3 bearings have the same main dimensions as the 62 and 63 single row deep groove ball bearings. In addition to the open type, there is also a steel dust cover ZZ type. In addition, when using a bearing, try to use the ball fill position of the outer ring as a non-loaded ring as much as possible. The cage is a stamped cage.

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
