The deep groove ball bearing is simple in structure and convenient in use, which has the largest production batch and the widest application range. It is widely used in automobile, home appliances, machine tools, motors, pumps, agricultural machinery, textile machinery and many other fields. Its output accounts for more than 70% of the total output of bearings, which is the most popular and cheapest type of bearing. KOYO 32006jr Bearing

Compared with other bearings of the same size, the deep groove ball bearing has the advantages of small friction coefficient, low vibration and noise, high limit speed and high precision, which is the preferred bearing type for users.

The inner and outer raceways of deep groove ball bearings are all arc-shaped deep grooves, and the radius of raceway is slightly larger than that of ball. It is mainly used to bear radial load and also to bear certain axial load. When the radial clearance of the bearing increases, it has the function of angular contact ball bearing, can bear large axial load, and is suitable for high-speed rotation.

In many cases, the bearing will be rusted, resulting in many reasons. The most common factors in our daily life are as follows:

1. Due to poor sealing device, it is invaded by water, dirt, etc;

2. The bearing is not used for a long time, beyond the rust proof period, and lack of maintenance.

3. The surface roughness of metal is large;

4. Contact with corrosive chemical medium, unclean cleaning of bearing, dirt on the surface, or contact with bearing with sweaty hands. After cleaning, the bearing is not packed or installed in time, exposed to the air for a long time, and attacked and contaminated by air moisture;

5. Environmental temperature and humidity and contact with various environmental media; rust inhibitor failure or quality does not meet the requirements.

In order to make the deep groove ball bearing play a good performance in use and extend the service life of the bearing, it is necessary to maintain the deep groove ball bearing in the use process of the bearing.

1、 Cleaning of bearing oil pollution

Since lubricating oil is an indispensable material to reduce the friction between bearing components during operation, it can completely rush into the bearing, wrap the cage and ball, greatly reduce the friction coefficient of deep groove ball bearing during operation, and extend the service life of the bearing. However, due to the frequent use of lubricating oil, there will be a certain amount of oil pollution. If not removed in time, it will affect the service life of the bearing, so it is necessary to remove oil pollution.

2、 Keep the bearing clean and avoid rusting

For the cleaned deep groove ball bearing, after adding lubricant, it shall be placed on the assembly platform, with a net cloth or paper pad under it and a plastic cloth covered on it for assembly. It is not allowed to put it on the ground or box. When moving the deep groove ball bearing, it is not allowed to use hands directly. You should wear canvas gloves or use clean cloth to contract the deep groove ball shaft before taking it. Otherwise, due to sweat and moisture on your hands, it is easy to cause internal fingerprint rust of the deep groove ball bearing after contact.

3、 Bearing fitting installation

The correct installation of deep groove ball bearing is the guarantee of prolonging service life. Due to the lack of professional knowledge of bearing installation, deep groove ball bearings are often not installed in place, which is easy to cause mechanical operation accidents due to improper installation of bearings. Therefore, the correct installation mode of bearings should be understood.
