Automotive clutch release bearing detailed explanation and purchase guide

 First, what is an automotive clutch release bearing?

Automotive Clutch Release Bearing (Clutch Release Bearing) is an important component in the automotive clutch system, mainly responsible for pushing the clutch pressure plate to separate the clutch plate from the flywheel when the driver presses down the clutch pedal, thus interrupting the transmission of power between the engine and the gearbox. This process ensures smoothness and comfort when the vehicle is shifting gears. Separation bearing is usually located between the clutch pressure plate and transmission input shaft, the working environment is extremely harsh, need to withstand high temperature, high load and high speed rotation conditions.

 Second, the working principle of automobile clutch release bearing

1. Depressing the clutch pedal: when the driver depresses the clutch pedal, the hydraulic system or mechanical linkage transmits the force to the clutch release bearing. 

2. Push the clutch pressure plate: the release bearing moves forward and pushes the clutch pressure plate to separate the clutch disc from the flywheel.

3. Interrupts power transmission: as the clutch disc separates from the flywheel, no more power from the engine is transmitted to the gearbox, allowing the driver to shift gears smoothly.

4. Release the clutch pedal: when the driver releases the clutch pedal, the release bearing returns to its original position, and the clutch pressure plate presses the clutch disc again, resuming power transmission.

 Third, the main components of automobile clutch release bearing

1. Bearing: internal ball or roller, used to reduce friction and wear. 

2. Shell: to protect the internal bearing, provide support and positioning.

3. piston: in a hydraulic system, the piston pushes the release bearing forward.

4. spring: in some designs, the spring is used to help the release bearing reset.

 Fourth, automotive clutch release bearing function and role

1. Smooth gearshift: to ensure smooth separation and combination of clutch disc and flywheel, and reduce the shock and vibration during gearshift. 

2. Prolong life: prolong the service life of the whole clutch system by reducing the wear and tear of the clutch system.

3. Improve safety: reliable release bearing can reduce the safety risk caused by clutch failure.

 V. Common Problems and Failures of Automotive Clutch Release Bearings

1. Wear due to lack of lubricant: clutch release bearing needs grease for lubrication. If this is neglected in practice, resulting in clutch release bearing lack of oil, then in the case of no lubrication or less lubrication release bearing wear will be lubricated several times to dozens of times, the temperature will also have a great increase in order to damage more easily.

2. Free travel is too small or loaded too many times: according to the requirements of the general clutch release bearing and the clearance between the release lever for 2.5mm is more appropriate, reflected in the free travel on the clutch pedal for 30 ~ 40mm. free travel is too small or no free travel at all, will make the release lever and the release bearing in the state of constant engagement, resulting in bearing working time is too long, damage is serious. At the same time, the more loaded times, the more likely to produce fatigue damage to the separation bearing.

3. Other factors: whether the separation lever is adjusted flat or not, whether the separation bearing return spring is good or not, etc. also has a great influence on the damage of the separation bearing. If the separation adjustment is not flat, the separation fork is deformed or the separation bearing spring does not return to the position, it will cause in the clutch work against the separation bearing, so that it is always in the working state, the temperature is getting higher and higher, so it is easy to burn the separation bearing, reduce its service life.

 Sixth, automotive clutch release bearing maintenance and maintenance

1. Avoid half-engaged and half-disengaged state: drive the vehicle according to the operation regulations to avoid half-engaged and half-disengaged state of the clutch, in order to reduce the number of times the clutch is used.

2. Regular lubrication: Pay attention to the maintenance of the vehicle, regularly or in the annual inspection and maintenance, using the steaming method to let the grease soak through the release bearing, so that it has sufficient lubricant.

3. levelling the clutch release lever: pay attention to levelling the clutch release lever to ensure that the spring force of the return spring is in accordance with the regulations.

4. Adjust the free stroke: Adjust the free stroke to meet the requirements (30~40mm) to prevent the free stroke from being too large or too small.

5. Smooth operation: try to press the clutch pedal lightly and easily during driving to make it smoothly engage and disengage.

 The price of automobile clutch release bearing

The price of automotive clutch release bearings varies depending on the quality, brand, model and sales channel. Here are some common price ranges:

- Economy vehicles: about RMB 100-300.

- Mid- to high-end vehicles: approximately between RMB 300-800.

- Luxury brand vehicles: may exceed RMB 1,000.

 VIII. Reasons for the price difference of automotive clutch release bearings

1. Brand and quality:

   - Original parts: usually produced by automobile manufacturers, reliable quality, but higher price.

   - Aftermarket parts: produced by third-party manufacturers, the price is relatively low, but the quality and warranty policy may be different.

2. Automotive clutch release bearing materials and technology:

   - High-quality materials and advanced manufacturing technology will lead to higher costs, which will result in higher prices.

   - Some high-end brands may use special lubricants and sealing technology to improve durability and performance.

3. Vehicle model and complexity:

   - The design of clutch systems varies from model to model, with some models having more complex release bearings that cost more to produce.

   - The release bearings of luxury brand vehicles usually have higher precision and durability requirements, so the price is also higher.

4. Region and automotive clutch release bearing sales channels:

   - Labour costs and transport costs in different regions will affect the final price.

   - The cost of 4S shop and professional repair shop is usually higher than that of general repair shop.

 Nine, how to choose the right automotive clutch release bearing?

When choosing a suitable automotive clutch release bearing, the following factors should be considered:

1. Suitability:

   - Make sure that the selected bearing matches perfectly with the vehicle model, transmission type and clutch specifications. Check the vehicle owner's manual or contact the vehicle manufacturer to confirm the specific model and specification of the required clutch release bearing.

2. Quality:

   - Give preference to well-known brands or certified quality products to ensure durability and reliability. Famous brands usually have stricter quality control system and better after-sales service.

3. Performance requirements:

   - According to the vehicle's usage environment, driving habits and maintenance schedule, choose the appropriate bearing performance level. For example, high-performance vehicles may require bearings with higher heat resistance and longer life.

4. Price:

   - Under the premise of ensuring quality and suitability, choose the appropriate price range according to your personal budget. It is not necessary to pursue the most expensive products, but to ensure cost-effective.

5. after-sales service:

   - Understand the supplier or seller's after-sales service policy, to ensure that in the process of use can get timely technical support and maintenance services.

Summary

Automotive clutch release bearing is a key component to ensure smooth gear shifting. Choosing the right release bearing requires not only considering the price, but also the brand, quality, applicability and user evaluation and other factors. The following are some suggestions for choosing the right clutch release bearing:

1. Determine the applicable model: Check the vehicle manual or contact the manufacturer to confirm the required model.
