What is the lifespan of car bearings?
2 Answers
Car bearings can generally last about 100,000 kilometers. The lifespan of bearings is related to the vehicle's operating environment. If the car is used in harsh conditions with poor road surfaces, bearing wear can be more severe, potentially requiring earlier replacement. Regular bearing replacement is also part of vehicle maintenance. Relevant information about car bearings is as follows: 1. The main functions of bearings (hub-bearing) are to bear loads and provide precise guidance for wheel hub rotation. They withstand both axial and radial loads, making them a crucial component. 2. Bearings serve two primary purposes: First, they ensure that the shock absorber can rotate with the wheels during steering, maintaining steering flexibility; Second, the outer ring of the pressure bearing is made of rubber, maintaining a flexible connection between the car body and the shock absorber, preventing vibrations from uneven road surfaces from being transmitted to the car body through the shock absorber during driving.
The lifespan of car bearings typically ranges between 100,000 to 150,000 kilometers, which really depends on your driving style and maintenance habits. Having driven for over a decade, I've noticed that frequent driving on bumpy roads or high-speed racing can accelerate bearing wear. Take my previous car as an example—when it hit 120,000 kilometers, there was a noticeable humming noise from the front wheels, clearly indicating a bearing failure. Repairing it cost a few hundred bucks, but delaying replacement poses safety risks. To extend their lifespan, I recommend regular maintenance checks by technicians and prompt troubleshooting if any unusual noises are heard. Drive gently in daily use, avoid potholes, and opt for high-quality bearings to ensure durability. Remember, these are wear-and-tear components—don't procrastinate on replacements.
