In fact, the damage to our bearings is largely not due to a lack of lubricating grease, but rather because the bearing material is poor and the rolling surface is damaged, causing the bearings to produce noise during rotation. If there is no problem with the bearings themselves, the design service life of this type of bearing structure can reach more than 200000 kilometers. Therefore, this type of bearing structure does not require maintenance and can be replaced if it is damaged.
In fact, for automotive parts bearings, our current household cars and automotive parts bearings do not require maintenance because their bearing load is not very high. Moreover, due to the advancement of bearing design technology, our household car bearings can be designed as maintenance free bearings
This is the rear wheel bearing we replaced from a family sedan, and this type of bearing does not require maintenance!
But we also have car parts bearings that need maintenance, such as our pickup trucks and a small number of heavy-duty off-road vehicles, which use bearings that require maintenance
This type of bearing requires maintenance and oiling. It is usually installed on our heavy-duty vehicles and can withstand larger loads! But in order to ensure its service life, maintenance is required every tens of thousands of kilometers, usually by disassembling and cleaning it, and then reapplying lubricating grease to ensure bearing lubrication and heat dissipation under high loads.
