Clutch Release Bearing 8014CST

The 8014CST Clutch Release Bearing is a key actuator in the clutch system of manual or automated manual transmissions in automobiles. Its core function is to precisely and low-frictionally transmit the axial thrust generated by the release fork or hydraulic actuator to the finger-shaped end of the clutch pressure plate's diaphragm spring (or coil spring lever) when the clutch pedal is operated. This disengages the clutch friction plates from the engine flywheel, interrupting power transmission and enabling gear shifting. This bearing assembly typically consists of a precision-manufactured deep groove ball bearing or angular contact ball bearing, ensuring high axial load capacity and low operating torque. The bearing unit is encapsulated in a housing made of engineering plastic (such as phenolic resin or reinforced nylon) or metal and features a specific mounting interface (such as a slot, flange, or friction bushing) for secure connection to the clutch release mechanism.

The 8014CST model is designed to adhere to specific dimensions (inside and outside diameter, height) and performance parameters (such as rated dynamic and static axial loads, limiting speed, and operating temperature range). It is pre-filled with high-temperature-resistant, long-life grease and features a sealed structure to withstand the high-temperature environment generated by clutch operation and achieve maintenance-free operation. The bearing must be precisely matched to the target vehicle's clutch release mechanism (fork type, travel) and pressure plate specifications to ensure accurate release stroke, smooth operation, and long-term reliability. Its performance directly affects clutch disengagement efficiency, pedal feel, and system durability, making it suitable for designated clutch assemblies in passenger cars and light commercial vehicles.
