Automobile bearing knowledge, classification of automobile bearing, installation method of automobile bearing

In life, the number of cars is increasing, and the demand for wheel bearings on cars is also increasing. The correct installation of car wheel bearings can increase the safety factor of the car. Excessive wear and bearing damage, if not replaced in time, will bring certain hidden dangers to driving safety. Classification of automobile bearings: single-row tapered shaft ◆ The inner ring and outer ring can be installed separately; ◆ The rear wheel that can be used for drum braking (such as the Santana rear wheel); ◆ It has a higher load carrying capacity and a relatively low speed; ◆ The installation space is small and easy to install; the first generation of bearings ◆ fixed, pre-set bearing clearance; ◆ life-long lubrication, maintenance-free; ◆ permanent seal; ◆ sealing ring is divided into: rubber oil ring, combined oil seal; ◆ compact structure;

The second-generation hub unit The second-generation hub bearing combines the advantages of the first-generation economy and integrates a hub flange, which is used to install the brake disc and the wheel flange. The second-generation hub bearing is a compact bearing. The unit has a fixed pre-set bearing clearance, is lubricated for life (maintenance-free), and is sealed. ◆ Integrate a hub flange; ◆ A certain pre-set bearing clearance, integrate the hub flange; ◆ Rolling flanging technology, fully pre-tightened; ◆ The snap ring provides the axial tension of the outer ring of the bearing, and makes the bearing Firmly fixed; ◆ Multiple sensors can be integrated in the sealing ring to support ABS (Anti-lock Braking System), ASR (Drive Anti-Slip Device), ESP (Electronic Stability System);

The third-generation hub unit The third-generation hub bearing is a highly integrated hub bearing unit with a mounting flange for installing the brake disc and a flange for installing the steering knuckle to ensure the highest running accuracy. The integrated speed decoder provides the signals required for ABS/ESP suspension control. The tightening force of the hub bearing is actuated and adjusted by the annular boss. ◆ Compact structure, high bearing capacity, life-long lubrication and sealing; ◆ Shaking is reduced, and driving comfort is improved; ◆ High-precision brake disc and wheel guidance; ◆ Double flange design, installation does not need to adjust the bearing clearance, and the installation is easier ; ◆ Higher life reliability and longer service life; ● Precautions for bearing installation

1. Under no circumstances should it be allowed to knock the bearing; 2. It is recommended to replace the hub bearing coaxially; 3. The bearing with a magnetic encoding ring cannot be reversed; 4. Do not attempt to disassemble the hub bearing or adjust the seal ring of the hub unit ; 5. Do not touch the magnetic encoding ring of the bearing, the bearing needs to be stored away from the magnetic field; 6. In any case, it is necessary to use the correct method to assist the appropriate tool for installation; 7. The construction needs to be carried out in a dry and clean environment. Do not open the package before installation; installation of tapered roller bearings

Note: Use a suitable press tool to install the bearing. Ensure that the bearing seat is clean and fully lubricated during press-fitting. Tighten the bearing bolts strictly in accordance with the model maintenance manual, otherwise the wheels will not turn or the bearings will be damaged. Installation of first-generation bearings

Note: Strictly tighten the half-shaft bolts in accordance with the vehicle maintenance manual. When press-fitting, ensure that the bearing seat is clean and fully lubricated. Do not forget the circlip, otherwise serious maintenance accidents may occur. Installation of the second generation bearing unit

Note: Strictly tighten the bearing bolts in accordance with the vehicle maintenance manual, and ensure that the installation shaft is clean during installation. Don't forget to adjust the shim (if any), otherwise other joint failures will occur. Installation of the third-generation bearing unit

Note: Strictly tighten the bearing and axle bolts in accordance with the vehicle maintenance manual, and make sure that the bearing seat hole is clean and free of dirt and grease during installation. Do not touch the magnetic coding ring.
