The release bearing belongs to the clutch system part of the automobile manual transmission, which is located at the back side of the clutch pressure plate and is a key component in the automobile transmission system. Specifically, it is installed between the engine and the gearbox, and is one of the key components connecting the engine and the gearbox.

What is a release bearing?

The release bearing, often referred to as the ‘clutch release bearing’, is a bearing used between the clutch and the transmission. Its main function is to push against the diaphragm spring on the pressure plate when the driver presses the clutch pedal, pushing the pressure plate to separate from the friction plate, thus cutting off the power output from the crankshaft and realising the separation of the clutch. The release bearing should move flexibly without any sharp noise or jamming, and it needs to be lubricated regularly to maintain a good working condition.

Is the release bearing part of the clutch assembly?

Yes, the release bearing is part of the clutch assembly. The clutch assembly usually consists of the following major components:

- Flywheel: directly connected to the engine crankshaft and provides the rotating platform for the clutch disc.

- Clutch disc: located between the flywheel and the clutch pressure plate, transmits power by friction.

- Clutch pressure disc: pressed against the clutch disc and in contact with the release bearing by means of a spring or pressure bar.

- Release bearing: Located between the clutch pressure plate and the release fork, it is used to push the pressure plate to achieve the release of the clutch disc.

- Release Fork: connects the clutch pedal to the release bearing and transmits the force of the pedal.

These components work together to realise the clutch's function of controlling power transmission between the engine and the gearbox. Among them, the release bearing, as one of the key components, plays a vital role in the smooth engagement and gentle disengagement of the clutch.

Therefore, the release bearing is one of the indispensable components in the clutch assembly, and it plays an important role in the working process of the clutch.

In summary, the release bearing not only belongs to the key part of the clutch assembly, but also plays an indispensable role in the automotive transmission system.
