What is a clutch release bearing?

Clutch release bearing definition and function

Clutch release bearing, also known as clutch release bearing or clutch throw-out bearing, is one of the indispensable parts in automobile manual transmission. It is located between the clutch and the transmission, and is responsible for pushing the clutch pressure plate to separate from the flywheel through mechanical or hydraulic mechanism when the driver presses the clutch pedal, interrupting the power transmission from the engine to the wheels, so as to allow the driver to carry out the operation of shifting gears.

Clutch Release Bearing Working Principle

- Operation process: When the driver depresses the clutch pedal, the clutch master cylinder generates hydraulic pressure, which acts on the release bearing to move it forward. The release bearing contacts and pushes the release finger (or release pawl) on the clutch pressure plate, resulting in the separation of the driven disc between the pressure plate and the flywheel, completing the power disconnection.

- Location: Usually mounted on the first shaft bearing cover of the transmission, between the clutch pressure plate and the transmission.

- Design features: Designed to rotate freely to reduce friction and wear when pushing the clutch pressure plate; some advanced designs also have automatic centring function to further improve working stability and service life.

Clutch Release Bearing Failure

If there is a problem with the clutch release bearing, possible symptoms include, but are not limited to: incomplete clutch disengagement, difficulty in shifting gears, abnormal sounds coming from the clutch area, and the clutch pedal feels heavy.

 Conclusion

Clutch release bearing is the core component to ensure the smooth operation of automotive manual transmission clutch system, and its importance is self-evident. Reasonable selection and timely replacement of good quality release bearings can not only safeguard the driving experience, but is also one of the important measures to maintain vehicle safety. When purchasing, it is recommended to prioritise the brand and model that matches your vehicle, while paying attention to the quality and reviews of the product to ensure the best results.
