6312 zz c3 deep groove ball bearing

Deep groove ball bearing is the most common type of rolling bearings.

The basic deep groove ball bearing is composed of an outer ring, an inner ring, a group of steel balls and a group of retaining structures. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is also divided into sealed and open structures. Open type means that the bearing does not have a sealed structure, and the sealed deep groove ball is divided into dust seal and oil seal. The material of the dust-proof sealing cover is steel plate stamping, which only plays a simple role in preventing dust from entering the bearing raceway. The oil proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.

The type code of single row deep groove ball bearing is 6, and the code of double row deep groove ball bearing is 4. With simple structure and convenient use, it is the most popular and widely used bearing.

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.

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.

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
