Clutch Release Bearing 306775B

Clutch Release Bearing 306775B is a key precision component in the clutch system of manual transmission vehicles. It is responsible for achieving smooth and reliable separation of engine power from the transmission input shaft when the driver operates the clutch pedal. It is located at the front end of the transmission input shaft and directly acts on the finger-shaped release finger (or lever) of the clutch pressure plate diaphragm spring. When the hydraulic pressure generated by the clutch master cylinder (or the mechanical force transmitted by the cable) drives the clutch slave cylinder (or shift fork), the bearing is pushed axially and accurately pressed against the release mechanism of the clutch pressure plate, thereby releasing the clamping force of the pressure plate on the clutch friction plate, interrupting the transmission of engine torque to the transmission, and providing the necessary conditions for smooth shifting. Its performance directly affects the lightness of clutch operation, response speed and smoothness of the entire transmission system. The working environment requires it to withstand high mechanical stress and a certain thermal load.

The design of the 306775B release bearing fully considers the durability and smoothness of operation under high load conditions. It is usually made of high-strength steel and integrated with precision needle roller or ball bearing units to ensure low-friction, high-precision rotational motion under frequent axial thrust. Optimized internal grease filling and efficient sealing structure are its core advantages, designed to provide long-term lubrication protection, effectively isolate external contaminants (such as dust, moisture) and internal grease leakage, significantly extend the service life of the bearing and maintain its performance consistency. The bearing has been strictly matched and verified to ensure perfect coordination with the release mechanism of the specified clutch pressure plate, provide a clear and consistent release point feeling, and effectively reduce operating noise. Its robust structure and reliable performance make it an important guarantee for the efficient, quiet and long-life operation of the clutch system under demanding daily driving and various working conditions.
