Why do car bearings do not need maintenance?
May 29, 2019
In fact, for the automotive bearings, our current family cars, car bearings are not maintenance.
Because for our family car, its bearing load is not very large, and due to the advancement of bearing design technology, our family car bearings can be designed as maintenance-free bearings. This is the rear wheel bearing we replaced from the family car, This type of bearing is not maintenance!
Because of this type of bearing, its design concept is different.
His design goal is to design as a maintenance-free automotive bearing.
Moreover, the load of our family car is not very large, so the normal use of the family car, between 100,000 to 200,000 km, may replace the car bearing.
The last oil seal will also be used on our automotive bearings. Our maintenance-free automotive bearings are equivalent to a single assembly. It contains lubricating oil and bearing parts with exceptional strength.
Seal our oil in the entire bearing body with our oil seals, which lubricate our bearings as we drive.
When we use it for a long time, the temperature of the bearing will become higher. These lubricants will become thinner. We seal these lubricants in our bearing body through our oil seals.
Do not let it flow out. After we parked, these lubricants will slowly cool down and the viscosity will become higher. This will repeatedly lubricate our bearings. Such design bearings can often use more than 100,000 kilometers.
And our kind of bearing, its design is very precise, because in order to prevent the inside of the lubricating oil from flowing out, it is very difficult if you want to maintain it.
It also affects the sealing of our entire bearing body! Bearing damage is largely due to the lack of grease, but because the bearing material does not wear on the rolling surface.
It causes the bearing to generate noise during the rotation process. If there is no problem in the bearing itself, the bearing design life of this structure can reach more than 200,000 kilometers, so the bearing of this structure is not to be maintained, and it can be replaced if it is broken.
