1. Automobile wheel bearings contain lubricating oil, and their precise structure ensures the durability of the bearings. Hengding wheel hub bearings indicate that as a key component supporting the weight of the wheel and the body, the bearings also need to withstand the friction and inertia force during rotation. Therefore, their quality and reliability play a decisive role in the overall safety and performance of the vehicle.
2. Automobile wheel bearings are not without lubricating oil, but the type of lubricating oil used is different from that used in the engine, which is a paste grease. Most domestic automobile wheels use ball bearings, which run smoothly and generate low heat
3. Private car tire bearings are closed structures and do not require additional lubricating oil. The grease medium used in the bearings is durable and not easy to leak, ensuring the safety of the bearings. Its lubrication is stable and there is no timeliness problem.
4. The four wheel hub bearings of a family car also do not require lubricating oil. These bearings are of different types. The front wheels are mostly flat needle bearings or double-row ball bearings, while the rear wheels may use tapered needle bearings. The bearings are well sealed to ensure that the internal lubricating oil is not contaminated or lost.
5. Although the wheel hub bearings of family cars do not need to be filled with lubricating oil, it does not mean that there is no lubricating oil in the bearings. They have good sealing properties and effectively prevent the pollution and loss of lubricating oil.
6. Modern cars mostly use conical bearings and bearing units. After many generations of development, such bearings can effectively disperse the axial force caused by wheel impact. The bearings contain lubricating oil, but there is no need to add or apply it regularly.
