Clutch throwout bearings are usually referred to as Clutch Release Bearing and they are functionally the same component. The clutch release bearing is a key component in the automotive clutch system, responsible for performing the power separation and engagement between the engine and transmission. When the driver depresses the clutch pedal, the release bearing pushes the pressure plate to separate the clutch plate from the flywheel, thus interrupting the power transfer. When the pedal is released, the release bearing resets under the action of the return torque, so that the power from the engine is retransmitted to the transmission.

The clutch release bearing is subjected to severe working conditions and has to withstand axial loads, shock loads and radial centrifugal forces during high-speed rotation. In addition, due to the fork thrust and the counterforce of the release lever are not in the same straight line, it will also form a torsional moment. Therefore, clutch release bearings need to have good performance characteristics such as wear resistance, high temperature resistance, precise guidance and low frictional resistance .

Damage can be caused by high operating temperatures, lack of lubrication, improperly set freewheeling travel or excessive loads. For example, a driver half-pressing the clutch while turning or decelerating, or over-adjustment of the vehicle's freewheeling travel, may result in the clutch being in a half-engaged, half-disengaged state, which generates a large amount of heat and transfers it to the release bearing, which may ultimately result in damage to the bearing .

In daily use, in order to prolong the service life of the clutch release bearing, the owner should pay attention to the light pedal, easy clutch, avoid frequent engagement and disengagement, reduce the impact load. At the same time, regular maintenance to ensure that the release bearing has adequate lubrication, and in accordance with the operating regulations, to avoid the clutch half-engagement and half-disengagement state .

Summarize:

Clutch Throwout Bearing and Release Bearing are actually the same kind of parts, just with different names. They play the same role in the clutch system, i.e., when the driver operates the clutch pedal, they are pushed hydraulically or by other mechanical means to separate the clutch pressure plate from the flywheel, thus realizing the clutch release function.

In different regions and contexts, this component may be called differently, but their functions and roles are the same. In short, the clutch throwout bearing and the clutch release bearing are two different names for the same component.
