Clutch Release Bearing 1177CST

The Clutch Release Bearing 1177CST is a core component of a manual transmission's clutch system, installed between the clutch fork and pressure plate. Its operating principle is as follows: When the driver operates the clutch pedal, the clutch release fork transmits force, pushing the pressure plate away from the flywheel and disconnecting power from the engine to the transmission. When the pedal is released, the pressure plate returns to its original position, and the clutch release bearing re-transmits power to the transmission input shaft, ensuring power transfer and enabling gear shifting.

This component utilizes a ball bearing and collar combination. The outer ring is connected to the clutch release mechanism and can move axially with pedal operation. The inner ring is fixed to the pressure plate release fork, transmitting power synchronously. Rolling elements (balls or needles) are positioned between the inner and outer rings to reduce friction during relative rotation. A cage assembly maintains the position and spacing of the rolling elements, ensuring stability during operation. Its design parameters are tailored to the clutch system specifications of specific vehicle models, meeting the high-temperature and load-bearing resistance requirements of the vehicle's transmission system, ensuring continuous clutch system operation.
