What is a clutch release bearing?

The clutch release bearing, also known as the ‘clutch release bearing’, is an important part that is installed between the clutch and the transmission. It is usually made of metal and is resistant to wear and durable. Its main function is to eliminate the heat and resistance generated by the direct friction between the clutch pressure plate and the fork during high-speed rotation, and to separate the pressure plate from the friction disc by pushing the pressure plate, thus cutting off the power output from the crankshaft and making it possible to shift gears.

The clutch release bearing works by transferring the force of the pedal to the clutch release fork, which then pushes the release bearing, which in turn pushes the clutch pressure plate to separate it from the clutch disc. During this process, the release bearing needs to withstand certain axial and rotational forces. Clutch release bearings are generally lubricated with grease to ensure their proper operation.

 How long does a clutch release bearing last? Clutch Release Bearing Life

Regarding the service life of the release bearing, there is no uniform standard for this because it is affected by a variety of factors. Generally speaking, the average service life of the release bearing is about three years, or driving more than 100,000 kilometres, or even longer. However, the specific service life will be affected by a variety of factors, mainly including:

 1. Driving conditions: Frequent starting, acceleration and deceleration operations will increase the burden on the release bearing, thus shortening its service life.

2. Vehicle maintenance: Regular inspection and replacement of lubricating oil, keeping the clutch system clean and dry and other maintenance measures can extend the service life of the release bearing.

3. Quality of parts: High quality release bearings usually have a longer service life.

4. Driving habits: Frequent half linkage, rapid acceleration, rapid deceleration and other bad driving habits will accelerate the wear of the clutch release bearing.

5. Vehicle environment: If you often drive in congested cities, the clutch will be used frequently, and the wear of the release bearing will be relatively fast.

 In addition, the damage to the release bearing may also be related to the following factors:

1. Improper setting of the clutch pedal free stroke, resulting in the release bearing often in the engagement state, causing fatigue damage or even ablation.

2. After the release bearing is eroded by dust, the grease deteriorates, aggravating its damage.

3. Poor fit of separation bearing and separation sleeve, especially large or loose fit gap, will lead to impact load on the separation bearing and accelerate its damage.

Therefore, in order to ensure the normal operation of the vehicle and prolong the service life of the release bearing, the owner should carry out regular maintenance and inspection of the vehicle, and replace the release bearing in time when it is found to have signs of damage. At the same time, attention should be paid to keeping the clutch system clean and dry to avoid dust and moisture intrusion. To ensure the normal operation of the release bearing and extend its life.
