Self aligning ball bearing is one of the most common types of rolling bearings. The basic type of self aligning ball bearing consists of a outer ring, an inner ring, a set of steel balls, and a group of holding structures. It can be used for gearboxes, instruments, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, construction machinery, roller type roller skates, Yo Yo and so on. In daily life, self aligning ball bearing is most prone to rust, which causes many reasons for bearing corrosion. The most common factors are the following.
(1) the cause of corrosion
1, the sealing device is bad, it is invaded by water, dirt and so on.
2, the long term is not used, more than the rust period, the lack of maintenance.
3, the surface roughness of metal is larger.
4, contact with corrosive chemical media, bearing cleaning is not clean, dirty dirt on the surface, or contact with the sweat bearing, bearing cleaning, not timely packaging or installation, long-term exposure and air, air moisture invasion and contamination.
5, environmental temperature and humidity and contact with various environmental media; antirust agent failure or quality is not required.
(two) anticorrosion method
1, soak the lubricating oil: soak the bearing in the antirust grease, so that its surface is attached with antirust grease.
2, brushed lubricating oil: using the method of brush coating, rust oil accumulation, save material, and can also effectively prevent corrosion.
3, lubricating oil spray: it is not practical to soak large imported bearings, and spray is the best way to use.
4, the cleanliness of the bearing is also crucial, the higher the cleanliness of self aligning ball bearing, the longer the life span.
Therefore, to prolong the service life of the bearing, it is very effective to apply the lubricating oil on the surface of self aligning ball bearing to ensure the cleanliness of the bearing.
