On this page, we aim to provide you with valuable information about automotive bearings. We will discuss various aspects of automotive bearings, including their classification, application areas, and factors to consider when selecting the right bearing.
Automotive bearing is an important car part, directly affecting performance, safety, and comfort. Automotive bearings are mainly divided into wheel bearings, transmission bearings, engine bearings, steering system bearings, etc. They play different roles in different parts of the car.
The application parts of automotive bearings are the engine, transmission system, steering system, auxiliary parts, etc. Automotive engine bearings are divided into internal bearings for crankshaft and camshaft support, needle roller bearings for valve rocker arms, and rolling bearings for timing sprockets. The steering system bearings include a steering column tube bearing, a small ball bearing for the EPS motor and reducer, a four-point contact ball bearing for the circulating ball power system, etc.

The structure of new energy vehicles bearing demand changes, but the total amount remains unchanged. As the energy of pure electric vehicles is transmitted through flexible wires instead of rigid couplings and rotating shafts, the engine and transmission with large bearing usage are omitted in pure electric vehicles. At the same time, to meet the requirements of driving, environmental protection, comfort, safety, etc., a large number of new demand for drive motor bearing products on electric vehicles.

There are several different types of automotive bearings, including roller bearings, spherical bearings, tapered roller bearings, and thrust bearings. Each type has specific characteristics and areas of application.
1, Poor quality wheel bearings - Wheel bearings are constantly under great stress. Wheel bearings made from poor-quality materials may need to be better heat treated, leading to premature wear and failure.
2, Faulty installation - Unsuitable tools (such as hammers or impact wrenches) may damage the wheel end bearing's outside and inside, leading to premature wheel bearing failure.
3, Driving conditions - Driving in deep water or mud may cause wheel bearing failure. Water, mud, or other contaminants (such as dirt or road salt) may pass through the seals and into the bearings, contaminating the grease and wearing the bearings.
Several factors should be considered when choosing an automotive bearing. The following are some of the key factors to consider:
1, Load capacity: Determine the maximum load the bearing will be subjected to in your application. The bearing should be able to withstand the expected load without premature failure.
2, Speed rating: Consider the speed at which the bearing will operate. The rated speed of the bearing should exceed the maximum speed of the application to prevent overheating and premature wear.
3, Durability and service life: Look for bearings that can withstand the specific operating conditions of your application. Consider factors such as temperature, humidity, and contaminants to which the bearing may be exposed. Longer life and durability will reduce maintenance and replacement costs.
4, Friction and efficiency: Choose low-friction and high-efficiency bearings to minimize energy loss and maximize vehicle performance.
5, Fit and compatibility: ensure that bearing dimensions, tolerances, and mounting requirements are compatible with the vehicle's axle or hub assembly.
6, Sealing and protection: Consider the level of sealing and protection the bearing provides. This is particularly important in automotive applications where bearings may be exposed to water, dirt, and other contaminants.
7, Noise and vibration: Select bearings that provide smooth, quiet operation to enhance comfort and the overall driving experience.
8, Cost: Evaluate the cost-effectiveness of the bearing, considering factors such as initial purchase price, maintenance requirements, and potential downtime costs.
It is recommended to consult TFL-Bearings online engineers for assistance, and we can help you select the best bearing for your specific automotive application.
No need; You need to replace the bad one. To be on the safe side, you need to keep the following two good habits:
1, Regular inspection: To maximize safety and reliability, no matter how old the vehicle is, it is important to check the rear wheel bearings frequently and pay attention to whether there are warning signs of bearing wear, including any frictional noise when turning or any abnormal deceleration of the suspension combination wheel when turning. For rear-wheel drive vehicles, it is recommended that the rear wheel bearings be lubricated when the vehicle reaches 38,000 kilometers. Check the bearings and replace the oil seal when replacing the brake system.
2, Noise treatment: When you hear noise from the bearing, first find the location where the noise occurs. Many moving parts may produce noise, or some rotating parts may be in contact with non-rotating parts. If it is confirmed that the bearing is noisy, it may be damaged and must be replaced.
