Why don't you need maintenance auto bearing, reason is such! - bearing knowledge

Actually for auto bearing, we are now a family car, auto bearing are not need maintenance. Because of our family car, its bearing load is not big, but because of bearing design technology progress, our family car bearing can be designed for maintenance-free bearings which we came down from above the family car replacement of the rear wheel bearing, this kind of the bearing is not for maintenance. Because this kind of bearing, its design concept is different also. He design goal is designed as maintenance-free auto bearing. And our family car use at ordinary times the load will not be very big, so use down to a normal family car, at around 100000 to 200000 kilometers, probably will change of auto bearing. The last of the oil seal will use on our car bearing. Our maintenance free car bearing it is equivalent to form a assembly. Containing lubricating oil, and particularly high strength of bearing parts. With our oil seal oil seal in the bearing body, when we travel, the lubricating oil will give us the bearing body of lubrication. In our long time use, bearing high temperature will change the lubricating oil will become thin, through our oil seal, the lubricating oil seal in our bearing body. Don't let it out with us after parking the lubricating oil and slowly cooling, high viscosity, such repeated for our bearing lubrication, so the design of the bearing tend to use more than 100000 kilometers. And we are this kind of bearing, its design is very sophisticated, because in order to prevent the inside of the lubricating oil flowing, so if you want to go to maintain it, will be very difficult. But also will affect our the whole bearing body sealing! Bearing damage is largely not because of a lack of grease, but because of the bearing material not rolling surface damage. Lead to bearing noise in the process of spinning, if bearing itself is no problem, the bearing design of the structure service life can reach more than 200000 km, so the structure of the bearing is not to maintain, bad and change it.
