“Automotive Bearings: The Unremarkable yet Crucial ‘Rotating Heart’—How Much Do You Know?” Automotive bearings, seemingly unremarkable components in a car, are actually the “rotating heart” of a car’s operation and play a key role in vehicle performance.Their primary function is to reduce friction. Just like in the wheel area, bearings make it easier for the wheels to rotate, reducing driving resistance, not only making the vehicle run more smoothly but also lowering energy consumption. At the same time, bearings also take on the responsibility of supporting the weight of the vehicle body. For example, hub bearings, when the vehicle is moving, have to bear the weight of the entire vehicle body and the impact forces from various complex road conditions, ensuring the stable operation of the wheels.There are various types of automotive bearings. Deep groove ball bearings are widely used. They can withstand radial loads and a certain degree of bidirectional axial loads. They are found in many parts of a car’s transmission system, are easy to install, and have high space utilization. Tapered roller bearings can bear both radial loads and unidirectional axial loads, have strong load – bearing capacity, and are often used in the front wheels of cars and other parts. There are also angular contact ball bearings, which can bear both radial loads and unidirectional axial loads, and play a role in some components with high requirements for precision and stability.Using inferior bearings can lead to endless troubles. The most obvious one is abnormal noise. During driving, you may hear a continuous buzzing sound, which will get worse when turning, seriously affecting the driving experience. Steering jamming may also be caused by inferior bearings, which greatly affects vehicle handling and poses a threat to driving safety.The automotive bearings we sell are made of high – quality steel in terms of material. This kind of steel has high strength and good wear resistance, which can effectively extend the service life of the bearings. In terms of craftsmanship, advanced processing technology is adopted to ensure the high precision of the bearings, reduce the noise during operation, and improve stability, making your driving safer and more comfortable. • “How to Read Tire Sizes? What Exactly Does 215/55 R17 Mean?” When you get a tire, the series of numbers and letters on it may be confusing. Take 215/55 R17 as an example. 215 represents the width of the tire in millimeters, referring to the width of the side of the tire that comes into contact with the ground. A wider tire usually provides better grip but may increase fuel consumption. 55 is the aspect ratio, which is the percentage of the tire’s section height to its width. A smaller value means the tire is flatter, with relatively better handling but possibly reduced comfort. R stands for radial tire, which is the most common tire structure nowadays. The cords are arranged radially, with high strength and low rolling resistance. 17 is the diameter of the wheel hub in inches, meaning this tire is suitable for a 17 – inch wheel hub. Different vehicle models and driving habits are suitable for different tires. For cars used for urban commuting, comfort and quietness are generally more important. You can choose tires with fine patterns and low noise. For example, our [brand name] tires have a pattern design that can effectively reduce the noise generated during driving, allowing you to enjoy a quiet driving environment even in urban traffic jams. If you often drive off – road, you need tires with strong grip and wear resistance. Our [off – road tire series name] tires have a unique block pattern design, which can firmly grip the ground in complex road conditions such as mud and sand, providing reliable driving force. Moreover, they use a special rubber formula, with excellent wear resistance, which can adapt to high – intensity off – road needs.  

When driving, if you hear some strange sounds, don’t take them lightly. They may be “distress signals” from the bearing. A buzzing sound during driving that gets louder as the speed increases is likely a sign of a bearing problem. Under normal circumstances, the vehicle runs smoothly. Once the bearing is worn, the internal structure changes, which will produce this abnormal buzzing sound. The increased noise when turning is also a typical symptom. Because when turning, the force on the wheels changes, and a faulty bearing cannot cope with this change normally, resulting in more obvious noise. In addition, if you manually shake the wheel after parking and feel obvious gaps and looseness, it also indicates that the bearing may be severely worn. For daily bearing inspection, you can regularly shake the wheel by hand to feel for abnormal gaps. You can also touch the hub part with your hand after the vehicle has been driven for a certain distance to feel if the temperature rises abnormally. If the temperature is too high, it may be caused by the abnormal operation of the bearing. It is very important to replace the faulty bearing in time, which can not only ensure driving comfort but also guarantee driving safety. When choosing a bearing for replacement, be sure to choose a reliable product like ours. Our bearings have passed strict quality inspections, and all performance indicators meet high standards, which can provide stable and reliable support for your car.

Want to make your tires last 20,000 more kilometers? Mastering these maintenance skills is enough. Regularly checking tire pressure is crucial. It should be noted that there is a difference between the tire pressure of cold tires and hot tires. It is generally recommended to check the tire pressure when the tires are cold and adjust it according to the standard values in the vehicle manual. If the tire pressure is too high, the contact area between the tire and the ground will decrease, the grip will be reduced, and it is easy to have a flat tire. If the tire pressure is too low, it will increase tire wear and also increase fuel consumption. Avoiding excessive load cannot be ignored. Every vehicle has a specified load limit. If it is overloaded for a long time, the tire will bear too much pressure, the internal structure will be damaged accelerated, and the service life will be shortened. Timely cleaning of small stones in the patterns is also important. If these small stones stay in the patterns for a long time, they will not only affect the drainage performance of the tire, making it easy to slip in rainy days, but also may puncture the tire during driving, causing safety hazards. Regular tire rotation can make the tire wear more evenly, thus extending its service life. Generally speaking, tire rotation can be carried out every 10,000 – 20,000 kilometers, and cross – rotation of front and rear tires is a common method. The tires we sell have obvious advantages in durability. They use a special rubber formula, which is tough and wear – resistant. According to actual tests, under normal maintenance, their service life is longer than that of ordinary tires, which can help you save the cost of replacing tires.
