The “throw-out bearing” is the heart of clutchoperation. When the clutch pedal is depressed, the throw-out bearing moves toward the flywheel, pushing in the pressure plate’s release fingers and moving the pressure plate fingers or levers against pressure plate spring force.
Clutch Release bearings are designed for engagement and disengagement of clutch in commercial vehicles and tractors.
The bearing reduces friction between the pressure plate levers and the release fork it has a front cover made of special heat-treated steel, for wear resistance during clutch engagement. Fitted with special accessories to prevent external contamination, the bearing is a sealed unit pack with a lubricant.
