Automobile hub bearing grease
It is suitable for lubrication of friction parts such as wheel bearing, chassis and water pump in the temperature range of -30℃ ~ +200℃, especially for high-speed buses, cars, all kinds of heavy-duty super-large vehicles and engineering vehicles.
It has good high and low temperature performance and mechanical stability, it does not emulsify and deteriorate in a long time when it meets water, it does not disperse grease at high temperature and high speed, it can greatly reduce bearing friction, reduce noise and vibration, it can protect bearing from impurities and dust, and it has long service life.
The main role of hub bearing is to bear load and provide accurate guidance for the rotation of the hub. It bears both axial and radial loads and is a very important component. The traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and adjustment of clearance of the bearings are all carried out in the automobile production line. This kind of structure makes it difficult to assemble, costly and unreliable in the automobile factory, and the bearings need to be cleaned, oiled and adjusted in the maintenance point of the automobile. Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearings, on the basis of it will be two sets of bearing as a whole, has the assembly clearance adjustment performance is good, can be omitted, light weight, compact structure, large load capacity, for the sealed bearing prior to loading, ellipsis external wheel grease seal and from maintenance etc, and has been widely used in cars, in a truck also has a tendency to gradually expand the application.
