Why do bearings fail prematurely and what are the reasons why bearings are often damaged

The impact of pressure bearing damage cannot be ignored, which can affect comfort, tire noise and vehicle deviation, while it can cause suspension damage, steering system failure and traffic accidents. The reasons for the occurrence are summarized below: 1. Turning the steering wheel in place or at low speed will make a "squeak..."The sound of "squeak", you can feel the steering wheel vibration when it is serious 2. The tire noise becomes significantly louder when driving, and there will be "buzz" when it is serious3. When driving on bumpy roads or crossing speed bumps, you will hear "knock..."4. The vehicle deviation can also be caused by the damage of the pressure bearing The life of the pressure bearing is generally 40,000 60,000 kilometers, and the impact on its life is not only the quality of the product itself, but also the driving habits and methods are also very important.

How can we extend its service life without premature breakage? 1. The pressure bearing carries a part of the weight of the body, and the vibration generated during driving will cause an impact on the pressure bearing through the suspension. Therefore, when driving, try to choose a road with good road conditions, and pay attention to avoid potholes or stones on the road surface as much as possible.

2. When encountering speed bumps, it is necessary to pay attention to deceleration and reduce the number of road teeth, which will also cause a great impact on the pressure bearing. 3. Try not to turn the steering wheel in situ, because the adhesion of the tire to the ground is the largest when the vehicle is stationary, and the pressure on the pressure bearing is also the largest.

Work beyond the norm.

Overworked.

Maintenance is not timely.

One of the most common points – improper use.

The most important point - lubrication is not in place.

The most lethal point - working with illness.

The above six points are the causes of "radial circularity" and accelerated bearing wear. Reduction of component service life (commonly known as eccentric wear).

Symptoms of broken bearings: 1. Turn the steering wheel in place or at low speed.

"Squeak..."squeak" sound, and in severe cases, you can feel the steering wheel vibrate. 2. When driving, the tire noise becomes significantly larger, and there will be "hum..."Buzz". 3. When driving on bumpy roads or passing speed bumps, you will hear "Knock..."Knock" sound.

4. Vehicle deviation can also be caused by damage to the pressure bearing. How to repair: 1:

Removing the tires allows you to see the car's brake discs.

and brake calipers, remove them to see the front wheel bearings. 2: Remove the outer dust cover of the bearing with the opening, and you can see the large nut that fixes the bearing.

Remove the nut with a sleeve of 30. 3: With an 18 torx wrench.

Remove the two screws that hold the brake caliper in place and slowly remove the caliper to prevent the brake hose from breaking. 4: Remove the brake disc on the outside, if the brake disc cannot be removed, you can use two screws to screw the brake disc hole, and tighten the screws with the corresponding wrench, you can remove the brake disc.

5: The strong nut on the outside of the bearing has been removed, and the bearing can be removed by pulling it out with both hands. 6:

Install the new bearing, replace the new strong nut, after tightening the nut, rivet the edge of the nut with an opening, so that the nut is stronger, and install the dust cover. 7: Install the brake disc and brake caliper, and the bearing will be replaced this time.

Hello, the bearing you asked is used in **, I provide a car front wheel bearing bad column, I hope to help you. Hello! If the front wheel bearing is damaged, if it is not very serious, the noise will be very loud and it will make a buzzing sound after driving, which is different from the tire noise.

You can drive for half an hour, get out of the car, and touch the hub with the back of your hand where you think the bearing is damaged

Hello dear<> there are many reasons for bearing damage, the following are the common ones: 1Wear and tear:

Long-term use can cause bearing wear, especially when lubricating oil is insufficient or contaminated. 2.Fatigue:

When a bearing is subjected to repeated loads and rotations, it can lead to cumulative fatigue damage to the bearing, which can lead to bearing damage. 3.Rupture:

Bearing rupture can be caused by overload or continued load after shutdown. 4.Thermal Damage:

When a bearing is accelerating, braking or overloaded, it can generate too much heat that can cause damage to the bearing. 5.Bad installation:

Incorrect mounting can also lead to bearing damage, e.g. over- or over-loose mounting, wrong reciprocating or rotation direction, lack of lubrication, etc. 6.Poor sealing:

If the shaft is not properly sealed after installation, dust and impurities can enter the inside of the bearing, causing damage to the bearing. 7.Insufficient lubrication or contamination:

Bearing damage can occur if it is not properly lubricated or contaminated with oil during long-term operation.

Dear, there may be the following reasons for frequent damage to bearings:1Poor bearing mounting:

If the bearing is not installed correctly, including in the wrong position, too tight or too loose, it will cause damage to the bearing. 2.Poor lubrication:

Bearings need to be lubricated with oil or grease to reduce wear and friction, and if lubrication is not done quickly, it can lead to overheating, increased wear, and eventually damage. 3.Overload Operation:

If the load on the bearing exceeds its rated load, it will cause the bearing to overload and run, thereby accelerating the damage of the bearing. 4.Pollution:

During the operation of the bearing, if it encounters contaminants such as dust, water, sand, etc., it will cause the bearing to be subject to additional wear, thus increasing the risk of bearing damage. 5.Material quality issues:

If the material quality of the bearing is not good, it will lead to a significant reduction in the life of the bearing, which will accelerate the damage of the bearing.

If the plane bearing is not replaced, it will affect the comfort, the tire noise will become larger, the vehicle will deviate, and the heavy will cause suspension damage, so that the steering system will fail and traffic accidents will occur. So how can you tell that there may be a problem with your pressure bearing? Here are a few points to summarize:

1. Turning the steering wheel in place or at low speed will make a "squeak..."squeak" sound, and in severe cases, you can feel the steering wheel vibrate. 2. When driving, the tire noise becomes significantly larger, and there will be "hum..."Buzz". 3. When driving on bumpy roads or passing speed bumps, you will hear "Knock..."Knock" sound.

4. Vehicle deviation can also be caused by damage to the pressure bearing. @2019

The following are the manifestations of the broken plane bearing: 1. Turning the steering wheel in place or at low speed will make a "squeak" sound, and the steering wheel vibration can be felt in severe cases. 2. When driving on bumpy roads or crossing speed bumps, you will hear the sound of "dong dong".

3. The tire noise becomes significantly louder when driving, and there will be a "buzzing" sound when it is serious. 4. The vehicle deviates. The following is a specific introduction to plane bearings:

1. The plane bearing is made of high-precision cylindrical rollers (needle rollers) to increase the contact length, so that the bearing can obtain high load capacity and high stiffness in a small space. 2. The cylindrical surface of the needle roller and cylindrical roller used in DF plane needle roller bearings and planar cylindrical roller bearings is the modified surface, which can reduce the edge stress and improve the service life.

If the flat bearing of the car is broken, the car will make an abnormal noise when driving, the direction of the car will deviate, the tire noise will increase during driving, and the steering wheel will become heavier. If the above situation occurs in the vehicle, go to a repair shop or 4S shop to find a professional for a detailed inspection.

**Automotive Flat Bearings:

Flat bearings, also known as pressure bearings, are located between the spring on the top of the shock absorber and the rubber on the top of the shock absorber. It is composed of steel balls, axle collars and seat collars, and is an important part of the automobile shock absorber system.

Functions of Flat Bearings:

Flat bearings mainly play the role of shock absorption and link to the car body, preventing the shock absorber from directly rubbing the car body. If the plane bearing is broken, the suspension system of the vehicle will produce an abnormal sound of "hitch hitch" due to friction, which will affect the steering system of the vehicle. Therefore, when we use cars in our daily life, we should try to avoid passing through the potholes at high speed to prevent the aircraft bearings from being damaged by the huge impact force.
