Release Bearing SACHS
The SACHS clutch release bearing 053151.231031 forms the connection between the rotating clutch and the static actuating system. It is responsible for making sure the clutch functions reliably.
The ever increasing efficiency optimization on modern drivelines results in an increasing susceptibility to vibration phenomena. The flexible SACHS clutch release bearing decouples vibrations that originate from the engine and are transmitted to the clutch system, thus reducing driveline vibrations.
Absolute noiselessness and uncompromising reliability under any kind of operating condition must be ensured over its entire service life. With the SACHS clutch release bearing from ZF it is possible to compensate for a potential assembly- or tolerance-related off set.
The Technology
There is normally no play between the clutch releaser and the clutch (diaphragm spring), i.e. the releaser rotates with the clutch disc. The actuating system generates a preload, which ensures that the clutch and the thrust ring rotate at the same speed. Differences in rotational speeds would cause noise and higher levels of wear.
SCHEMATIC STRUCTURE
TESTING AND INSTALLATION
To reduce weight, most release clutch bearing housings from SACHS, among others, are now made of synthetic materials. Special plastics which have been modified with regards to wear, friction, and form stability are used for the sliding sleeve. The inner and outer ring of the clutch release bearing are high-precision, high-strength steel parts. In order to guarantee reliable lubrication of the ball-bearing grooves over the entire service life, only special grease is used.
Quality "Made in Germany"
The clutch systems from ZF Race Engineering have brought motor sports teams worldwide to the forefront, from mass sports to Formula 1.
The knowledge gained from these race series has been flowing into the development of High Performance products for years.
Clutch release bearing
The clutch release bearing transfers the force from the clutch pedal to the clutch, separating engine and gearbox when you change gear. As an original ZF SACHS part it is made to original-equipment quality, made in Germany and precisely to OE reference.
What the release bearing does
The clutch release bearing (also called throw-out bearing) sits on the gearbox input shaft and, when the clutch pedal is pressed, pushes against the diaphragm spring of the pressure plate. This opens the clutch and interrupts the power flow between engine and gearbox so the gears can be changed smoothly. As a moving part it is subject to wear.
Why the release bearing is replaced together with the clutch
Because the gearbox has to be removed for the job, it makes sense to replace the release bearing together with the clutch. A worn release bearing often shows through a grinding or rumbling noise when the pedal is pressed. Renewing the release bearing during the clutch change avoids doing the work twice.

Frequently asked questions about the clutch release bearing
What does the clutch release bearing do?
The clutch release bearing transfers the force from the clutch pedal to the pressure plate and thereby opens the clutch. This interrupts the power flow between engine and gearbox when changing gear.
When does the release bearing need to be replaced?
When a grinding or rumbling noise occurs while pressing the clutch pedal, or the clutch is hard to disengage. It is usually replaced together with the clutch.
Should the release bearing and clutch be replaced together?
Yes. Because the gearbox has to be removed for both jobs, replacing them together saves labour costs and makes technical sense.
Is this release bearing an original part?
Yes. It comes from ZF SACHS, an original equipment manufacturer, matches the respective OE reference and is made in Germany.
