What is a pendant bearing?

On the propeller shaft in the car is an important element of the structure called "suspension bearing." It is necessary to maintain the correct position of the propeller shaft and axis, as well as to perceive and transfer the load both axial and radial. A similar product provides rolling, rotation and linear movement along the axis, produced with the least resistance.

The suspension bearing is structurally composed of a metal body with an opening in it, into which a bushing is inserted. The gap formed between them is filled with a lubricant that allows easy movement of the main parts relative to each other. This significantly reduces the friction of the elements against each other, reduces the value of thermal conductivity, protects against negative environmental influences, and also increases the reliability and efficiency of the mechanism.

The main operational features and design advantages of the suspension bearing:

• Vibration resistance;
• Noiselessness;
• The possibility of work with significant radial and angular loads;
• Effective protection against aggressive media;
• Simplicity of repair.

The first signs of a malfunction are a strong impact on the body, which can be felt through the seat, after a while there may be a rumble and vibration. The most common problem is the aging and wear of the rubber. In this case, you must immediately contact the car service, since the replacement of the suspension bearing is possible only when removing the entire propeller shaft.

Here are some recommendations for the selection and purchase of this spare part.

1. If possible, purchase bearings in specialized auto shops that guarantee the availability of quality and new equipment. Because when you buy a used item, you can not even guess its lifespan, so you can not tell when it will fail if it is installed on your car.

2. Choose only original spare parts that fit your car. If the required model is removed from production, then you should contact the manufacturer. In such cases, it gives some recommendations and gives an example of a substitute that is as close as possible to the original design.

3. Check if there is enough lubricant. The suspension bearing could already be filled with lubricant at the factory, and could be released "dry". In the first case, an immediate installation is possible, in the second it is necessary to carry out some additional actions for filling with the bearing lubrication. These activities are not complex and are often described on the label or packaging of the product.

4. When buying, identify the lack of backlash. It is believed that the presence of play on the new bearing is an industrial fault, and the sifting of substandard products is carried out at the factory. However, no one is immune from error. Therefore, immediately with the seller, check the integrity and serviceability of the structure being purchased.

The suspension bearing is an integral part of the propeller shaft, hence the service life of this part of the structure depends directly on the nature of the vehicle operation as a whole.
