How to improve the service life of automobile wheel hub bearings?Usually the Car wheel bearings can have a long life under correct use. If they are damaged prematurely, it is likely to be caused by wrong selection, improper use, poor lubrication, or improper installation. When selecting wheel bearings, the selection should be made according to the proper installation position, lubrication conditions, and surrounding coordination. By researching and summarizing the types of bearing faults and the environment when the problem occurs, to avoid the recurrence of the fault. Therefore, it is required to continuously improve the service life of wheel hub bearings on the existing basis.A variety of bearings are used in the wheel hubs, transmissions, and differentials of automobiles, such as ball bearings, needle bearings, tapered roller bearings, linear bearings, sliding bearings, etc., and the amount of each vehicle is as many as dozens . In addition, people have put forward higher requirements for the safety, operability and life of automobiles during use. Therefore, it is necessary to find out the factors that affect the life of automobile wheel bearings, and find a targeted technical way to extend the life of automobile wheel hub bearings. Carry out a durability test through a real vehicle to determine the degree of improvement to the condition of the vehicle.1.Clean smelting technology of wheel hub bearing materialsTo solve the problem of possible quality defects inside the steel used to make bearings, clean smelting technology can be used to improve the performance of the steel. Wheel Bearing material is also the main factor affecting the early failure of bearings. With the continuous development of new bearing materials, the range of material selection for wheel bearings is becoming more and more tolerant. It is very important to choose suitable materials according to design requirements and environmental requirements. It mainly includes the following two aspects:1) By adopting advanced smelting technology, such as ladle refining, vacuum degassing, etc., to improve the purity of the steel itself, reduce the content of impurities and oxygen, and reduce the phenomenon of stress concentration, so as to make the steel itself anti-friction, anti-fatigue, and anti-impact Performance is improved.(2) During the smelting process, alloy components, such as chromium and nickel, are added to the steel to strengthen the hardness and stability of the material matrix. Tests have shown that the fatigue resistance of wheel bearings can be increased by more than 6 times after adding alloy components.2.Wheel Hub Bearing surface modification technologySince the surface layer of the wheel bearing is one of the key factors that determining its service life, the wear resistance and fatigue resistance of the rolling parts of the wheel hub bearing and the inner and outer raceways can be improved by modifying the bearing surface, so as to prolong the lifetime of the wheel bearing. Specifically, the following measures can be taken:(1) The surface layer of the wheel bearing can be carburized. That is, the hub bearing parts are placed in the active carburizing medium and kept at high temperature for a sufficient time so that the surface reaches a high carbon state without changing the internal structure. After carburizing, the inside of the hub bearing is tough and the surface is hard. Therefore, the anti-wear, anti-fatigue and anti-impact properties of the wheel hub bearing can be improved to varying degrees.(2) The advanced laser surface modification method can be used to modify the surface layer of the wheel bearing to obtain higher surface hardness, strength, wear resistance, corrosion resistance, and appropriate surface roughness, and then obtain a longer service life.(3) Use ion implantation technology to inject high-energy ion beams into the surface layer of the wheel hub bearing material. With the gradual loss of ion beam energy, it stays inside the material, thereby causing changes in the material composition of the wheel bearing surface and optimizing the performance of the surface, can significantly improve the wear resistance of each contact surface of the wheel hub bearing.Why choose HDAG Brand wheel hub bearing?Because ofHDAG wheel hub bearing unit has the advantages of good assembly performance, clearance adjustment can be omitted, light weight, compact structure, large load capacity, grease can be filled in advance for sealed bearings, external hub seals can be omitted, and maintenance-free, Good performance,fatigue durability,precise dimensions etc.Product description HDAG NEW OE replacement auto wheel bearing hub unit for TESLA model S 2WD 2012-2016 1027121-00-A 1044121-00-E 1044122-00-E   Item Name         Auto/car WHEEL BEARING,WHEEL BEARING HUB, WHEEL HUB BEARING, wheel hub unit,wheel bearing kit,pilot ball bearing,cross bearing spider kit,clutch release bearing,hub bearing assemblyOEM/REF NO.              1027121-0
