VBF Clutch bearings are used in the part that transfers or shuts off the driving force.
When the driving force is shut off, the clutch release bearing is affected by a strong force from the high-speed rotating diaphragm spring, and starts to rotate suddenly. If there is a significant gap between the rotation centers of the diaphragm spring and the clutch release bearing, the contact surfaces are likely to generate heat and wear, and this greatly impacts the clutch function.
