Knowing the types of car wheel bearings will help you to quickly notice the problem in your car wheel when necessary and avoid additional costs as well as damage to other parts in your car. Do not forget that each of these bearings can have its own characteristics, and for this reason, it is essential to know them.
What is a car wheel bearings?
First of all, we need to know what a car wheel bearing is and how it works. If there is a problem with the wheel bearings or any other type of bearing in the car, that part and that wheel have a problem and can no longer function well.
If we want to replace the bearing To explain in simple terms, we must say that these parts are actually gears that have their own special functions. Bearings consist of two parts. One part is known as Bal, which means Persian ball, and the other part is called Bearing, which means bearing.
But what is the main function of bearings in a car or any other industrial equipment? The main task of these parts is to reduce and minimize the friction between two car parts and also to prevent two parts from pulling on each other. If you can keep the car bearings in a good condition, you will never have problems related to the stretching of two parts of the wheel or the engine.
The main components of bearing
Many times when the bearings are damaged, actually one of these internal parts has a problem and you can only replace the same part if possible and you don't need to replace all the parts of the bearing. Don't forget that different parts of bearings have different roles in the overall performance of this spare part.
Outer ring, inner ring, balls, rack and cover are 5 parts that you can find in a bearing. . The cap part may not exist in some bearings and this issue can cause that bearing to become 4 parts instead of 5 parts.
The types of car wheel bearings
In order to be able to know the types of car wheel bearings, it is better to pay sufficient attention to the contents mentioned in this section. Usually, the types of wheel bearings include several different models, the roller type of which is more common than other models.
*Roller bearings
The first model that we are going to introduce is known as roller bearings. It is very common to use this model of parts in the wheels of passenger cars such as sedans, crossovers, etc. However, this model of parts has a big and almost gross problem, which includes the lack of adjustability and versatility of roller bearings as much as round ball bearings. bear and overcome the weight that is placed on them. However, they are not considered the best option for bearing the lateral forces that enter the wheels, and this issue can be considered a big disadvantage for them. or if it is too much, it is better not to use this model of bearings; But if the rotation speed of the wheel is not so high, roller bearings can be a suitable option.
*Careful bearings
The second type of car wheel bearing is known as precision wheel bearing. The high performance of these bearings can be considered as their positive option. In fact, precise bearings have the ability to reduce the amount of friction between the parts to the minimum possible amount and also reduce the amount of heat caused by the movement and rotation of the parts. He said that the rotation speed of this model of parts is usually higher than the rotation speed of normal bearings. For this reason, this model of bearings is used in wheels that have a very high speed. One of these models of wheels is related to airplane wheels, because the airplane reaches a speed of 400 km/h at the time of take-off. The next use of precision bearings is in the wheels of racing cars and fast cars in the world. Like Bugatti, Lamborghini, etc. In fact, precision bearings have been specially designed for very high radial and thrust forces.
*Angled roller bearing
The third case is related to angular roller bearings. This type of car wheel bearing is used in the normal wheels of cars and trucks, which also have a conical shape and can greatly lower and reduce the amount of high thrust when the wheels rotate. When you turn the steering wheel of the car, the angle that the wheels take can be different and this issue may cause the internal parts of the wheels to be crushed. However, if you use roller bearings in car wheels, this will not happen.
*Back -wheel ball bearings
The next item is also known as rear wheel hub bearing. Some cars use rear wheel hub bearings. In these bearings, a hub is placed, which is considered as a complete unit and must be installed separately. In such a case, if the car wheel bearing has a problem, instead of replacing one bearing, you have to replace the entire set, and this issue can be considered as one of the defects of these bearings.
