Do you know the causes of thrust clutch bearing failure?

When the thrust clutch bearing is working, the force of the clutch pedal will be transmitted to the clutch release bearing. 

The clutch bearing moves toward the center of the clutch pressure plate, so that the pressure plate is pushed away from the clutch plate, separating the clutch plate from the flywheel. When the clutch pedal is released, the spring pressure in the pressure plate will push the pressure plate forward, pressing it against the clutch plate, separating the clutch plate and the clutch bearing, and complete a working cycle.

Causes of thrust clutch bearing failure

The thrust clutch bearing is a relatively important part of the car. If it is not well maintained and malfunctions, it will not only cause economic losses, but also it is quite troublesome to disassemble and assemble once, which takes a lot of man-hours. Therefore, to find out the cause of the failure of the clutch release bearing, and to maintain and maintain it reasonably during use, is of great significance to prolong the life of the release bearing, improve labor productivity, and obtain better economic benefits.

Excessive operating temperature causes overheating. Many drivers often half-depress the clutch when turning or decelerating, and some have their feet on the clutch pedal after shifting; some vehicles have too much adjustment of the free stroke, which makes the clutch disengagement incomplete and in a semi-engaged or semi-disengaged state. The condition causes sliding friction between the friction disc and the flywheel, which produces a large amount of heat transfer to the thrust clutch bearing. The bearing is heated to a certain temperature, and the grease melts or dilutes and flows, which further increases the temperature of the release bearing. When the temperature reaches a certain level, it burns  release bearing.
