Double Row DAC39720037 Wheel Hub Bearing
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 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.
Auto Front Wheel Hub Bearing DAC35650035
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.

The thrust ball bearing is composed of race,shaft washer and steel ball retainer.The one that matches with the axis is called washer.The one that matches with the shell is called the ring. Thrust ball bearing is a kind of separation bearing. The shaft ring and seat ring can be separated from the cage and steel ball components. Thrust ball bearing is designed to withstand thrust load at high speed and is composed of a gasket-shaped ring with a ball rolling groove.Owing to its cushion-shape ring,the thrust ball bearing is divided into flat-base cushion type and aligning spherical surface cushion type.
There are two key points in the assembly of thrust ball bearings. One is the control of the pressing quality of the cage and the steel ball, and the other is the control of the nominal height T after the assembly of the bearing.Small thrust ball bearing seat ring and shaft ring inner diameter size difference is very small, there is no obvious difference between the two bundles. In order to prevent the phenomenon of mixed sleeves, that is, a set of bearings installed are found to be both seat rings or shaft rings.
51313 Size 75*135*44mm Thrust Ball Bearing
There are two key points in the assembly of thrust ball bearings. One is the control of the pressing quality of the cage and the steel ball, and the other is the control of the nominal height T after the assembly of the bearing. In addition, since the shaft ring and the seat ring can be separated, there is a management problem. It is to prevent the mixing of imported bearing parts. The M-type press cage uses a curved edge assembly die. After pressing, the steel ball is required to rotate flexibly in the pocket hole, but it can not fall off from the pocket hole, and the technical procedure to check the momentum of the steel ball in the pocket hole. If the solid cage is imprinted too deeply, the momentum of the steel ball will be small, and the connection between the embodiments and the cage is too little and the strength is insufficient, which is easy to fall off and cause the cage to be scrapped.
Thrust ball bearings are designed to take axial (thrust) loads at high speeds, but they cannot take any radial loads. These bearings feature bearing washers with raceway grooves in which the balls move.
