The clutch thrust bearing (also known as the release bearing or the throw-out bearing) is a small but important part of your car’s clutch system. It is mounted on the housing of your clutch and slides on a hollow shaft. Attached to the clutch bearing is the clutch fork, which moves the clutch bearing with the help of hydraulic or cable pressure.
While the clutch pedal is pushed down, the bearing moves inward. The bearing will apply pressure to the spring of the pressure plate, freeing the clutch disc from the flywheel and interrupting the transmission. This allows you to correctly and safely engage and switch gears.
