Deep groove ball automotive bearing are the most commonly used rolling bearings. It's simple and easy to use. Mainly used to bear radial load, but increase the bearing radial clearance, with certain features of the angular contact ball bearings can withstand radial and axial joint load. When should not be used in high speed and thrust ball bearings, can also be used to bear the pure axial load. Deep groove ball bearings with the same sizes of other types of bearings, such bearings friction coefficient, high speed limit. But the impact of intolerance, unfit to bear heavy loads.
In many cases, bearing corrosion will occur, leading to corrosion of bearings There are many reasons, the most common in our daily lives mainly in the following several factors.
1) due to poor sealing means is penetrated moisture, dirt, etc.;
2) bearing long-term need, more than rust period, the lack of maintenance.
3) the metal surface roughness is relatively large;
4) contact with a corrosive chemical media, bearing cleaning is not clean surface dirt buildup, or sweat hand contact bearings, the Hydrodynamic Bearing cleaning, packing or installation is not timely, long-term exposure to the air, water and air by the invasion contamination;
5) the ambient temperature and humidity and exposure to various environmental media; rust inhibitor failure or quality does not match the requirements.
