DAC4072W-3CS85 Wheel Hub Bearing

Hub bearing is the main role of bearing and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important part. The traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are all carried out on the automobile production line.

Product Introduction:
Hub bearings are very important part in terms of vehicle safety. Selecting the type of bearing most suited to the vehicle ensures safety and is very important for exhibiting the required performance. To select the best bearing, one must consider and evaluate the bearings from a variety of angles.

Life of hub bearings is calculated by inputting reaction force (radial load and axial load) on the wheel given as set traveling conditions as load. Each bearing is a unit bearing consisting of two rows of bearings. Life of the bearings is calculated separately for the each of the bearings. Bearing life is calculated for the outer and inner bearings.

Hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It combines the two sets of bearings as one. It has the advantages of good assembly performance, can omit clearance adjustment, light weight, compact structure, large load capacity, for sealing bearings can be loaded into grease beforehand, omit the external hub seal and avoid maintenance, etc., and has been widely used in cars. There is also a trend of gradually expanding the application in the truck.

Hub bearing is one of the key parts of the automobile, its main role is to carry weight and provide accurate guidance for the rotation of the hub, which requires it to bear not only axial load but also radial load.
