Regarding the size parameters of 6202 bearings, many people don’t know about 6202, let’s take a look now!轴承6803 (2)

6206 bearing 6——Bearing type, representing deep groove ball bearing; 2——The width series is 2; 02——Indicates that the inner diameter is 15mm. Its dimensions are: inner diameter 15mm, outer diameter 35mm, width 11mm.

The original list of deep groove ball bearings is radial ball bearings, which are the most widely used rolling bearings. It is characterized by small frictional resistance and high speed. It can be used on parts that bear radial loads or joint loads that act simultaneously in radial and axial directions, and can also be used on parts that bear axial loads, such as small-power motors, Automotive and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

Note: For deep groove ball bearings, if the bearing load is too small during operation, sliding will occur between the ball and the raceway, which will cause abrasion. Especially large deep groove ball bearings with high ball and cage weights have this tendency.

In many cases, bearings will rust. There are many reasons for bearing corrosion. The most common factors in our daily life are the following:

1) Intruded by moisture, dirt, etc. due to poor sealing device;

2) The bearing has not been used for a long time, beyond the rust prevention period, and lacks maintenance.

3) The roughness of the metal surface is relatively large;

4) In contact with corrosive chemical media, the bearing is not cleaned cleanly, there is dirt on the surface, or the bearing is touched with sweaty hands. After the bearing is cleaned, it is not packaged or installed in time, and it is exposed to the air for a long time, and is attacked by air moisture and contaminated;

5) Ambient temperature and humidity and exposure to various environmental media; rust inhibitor failure or quality does not meet the requirements.
