SINOTRUK Truck Clutch Release Bearing Assembly / Clutch Throw-Out Bearing Assembly AZ992116003001 Clutch System / Transmission System Parts

The AZ992116003001 Clutch Release Bearing Assembly is an important component of the SINOTRUK heavy-duty truck clutch system, providing the mechanical interface between the clutch release mechanism and the clutch pressure plate. During normal driving with the clutch engaged, the pressure plate applies clamping force to the driven disc, allowing engine torque to pass through the clutch and into the transmission. When the driver presses the clutch pedal, the clutch operating mechanism moves the release bearing toward the pressure plate. The bearing then transfers the required axial force to the pressure plate while accommodating the rotational movement of the clutch assembly, allowing the driven disc to separate from the engine-side friction surfaces and temporarily interrupt torque transmission. This operating process enables controlled gear changes and smooth clutch engagement and disengagement. For heavy-duty trucks, the release bearing works under repeated mechanical loading, rotational movement, and temperature changes inside the clutch housing. During long-distance transportation, urban delivery, construction operations, and other applications involving frequent gear changes, the bearing is repeatedly engaged and released as part of the clutch operating cycle. A correctly matched release bearing assembly helps maintain consistent clutch operation and proper pressure-plate movement. The AZ992116003001 is identified in SINOTRUK parts information as a clutch release bearing assembly and is listed together with other clutch components such as the clutch pressure plate and driven disc.
