The OE Match Clutch Release Bearing also known as a throw-out bearing, is a high-quality replacement clutch system component designed to transfer force from the clutch release mechanism to the clutch pressure plate. Manufactured to OE specifications for fit, performance and durability, this precision-engineered bearing plays a vital role in ensuring smooth clutch engagement and disengagement.
PLEASE NOTE: These require additional lubrication. This can be done through the two small holes at the back. It appears that otherwise they run dry too quickly.

Constructed from premium-grade bearing materials and designed to withstand continuous rotational forces, heat and mechanical loads, the clutch release bearing enables the clutch assembly to operate smoothly while minimising friction and wear. It is an essential component for maintaining proper clutch performance, gear selection and driving comfort.
What This Product Does:
- Transfers force from the clutch release fork to the pressure plate.
- Enables smooth clutch disengagement when the pedal is pressed.
- Allows rotational movement between stationary and rotating components.
- Reduces friction within the clutch release mechanism.
- Supports smooth gear changes and transmission operation.
- Helps maintain consistent clutch pedal feel.
- Contributes to overall drivetrain reliability and performance.
Symptoms Of Wear Or Failure:
- Squealing, whirring or grinding noises when the clutch pedal is depressed.
- Noise that disappears when the clutch pedal is released.
- Rough or inconsistent clutch pedal operation.
- Increased clutch pedal effort.
- Vibration felt through the clutch pedal.
- Difficulty engaging or changing gears.
- Clutch drag or incomplete disengagement.
- Excessive wear within the clutch release mechanism.
- Complete clutch operation failure in severe cases.
Why Replacement Matters:
- The clutch release bearing is subjected to constant mechanical loading, rotational movement and heat whenever the clutch is operated. Over time, the internal bearing surfaces can wear, lubrication can deteriorate and bearing clearances can increase, leading to noise, vibration and reduced performance.
- A failing release bearing can affect clutch operation and place additional stress on the pressure plate, release fork and other clutch components. If left unresolved, bearing failure can lead to difficult gear changes, clutch disengagement problems and potentially extensive clutch system damage requiring major repairs.
- Replacing a worn clutch release bearing restores smooth clutch operation, improves driving comfort and helps protect other clutch components from premature wear. An OE Match replacement provides factory-style fitment, precision manufacturing and dependable long-term durability, ensuring reliable clutch performance and helping maintain the driving experience expected from your Porsche.

Porsche Clutch Release Bearings | Smooth, Silent & Precise Clutch Operation
Clutch release bearings are crucial components within your Porsche’s clutch system, ensuring smooth engagement and disengagement of the clutch. Also known as throw-out bearings, they allow the clutch pressure plate to operate seamlessly when the pedal is pressed, reducing friction and maintaining consistent pedal feel.
At Design911, we supply premium clutch release bearings engineered to meet or exceed original performance specifications. Each bearing is precision-machined, sealed, and lubricated for durability, ensuring silent operation and reliability under extreme heat and load conditions.
Whether you’re performing a clutch replacement, solving noise issues, or upgrading for performance reliability, our Porsche clutch release bearings deliver long-lasting smoothness, precision, and peace of mind.
What Do Clutch Release Bearings Do?
The clutch release bearing serves as the critical link between the clutch fork or slave cylinder and the pressure plate. It allows for the controlled engagement and disengagement of the clutch system when the pedal is operated.
Core Functions:
- Provides a smooth, low-friction interface between clutch fork and pressure plate.
- Allows consistent clutch engagement and disengagement.
- Reduces noise and vibration during pedal operation.
- Maintains correct alignment and pedal feel.
Without a properly functioning clutch release bearing, your Porsche’s clutch pedal may feel rough, noisy, or unresponsive — and clutch operation can become erratic or stiff.
Why Do Clutch Release Bearings Fail or Wear Out?
Release bearings are constantly exposed to rotational forces, heat, and friction. Over time, wear or contamination leads to reduced lubrication, noise, and eventual failure.
Common Causes of Failure Include:
- Lack of lubrication or grease breakdown.
- Contamination from clutch dust, oil, or road debris.
- Excessive heat from prolonged clutch use or slipping.
- Misalignment during installation or worn guide tubes.
- Bearing surface pitting or corrosion.
When a bearing fails, symptoms include squealing, grinding, or rattling noises when pressing the clutch pedal — clear signs replacement is needed to prevent further clutch system damage.
Why Replace Your Porsche Clutch Release Bearing?
Replacing a worn or noisy clutch release bearing ensures smooth, quiet clutch operation and prevents costly damage to the clutch assembly. Upgraded bearings offer enhanced sealing, heat tolerance, and wear resistance — ideal for performance or heavy-duty applications.
Key Benefits:
- Eliminates clutch noise, vibration, and stiffness.
- Ensures smooth and precise clutch pedal operation.
- Extends clutch system lifespan by reducing component wear.
- Built from durable, high-tolerance materials.
- Suitable for standard, performance, or motorsport use.
- Recommended during every clutch replacement for best results.
Replacing the bearing together with the clutch disc and pressure plate guarantees balanced wear and reliable, consistent performance.
Highlights
- Premium Porsche clutch release bearings for smooth operation.
- Precision-engineered for quiet, friction-free performance.
- Heat- and corrosion-resistant construction for longevity.
- Ideal for Porsche 911, Cayman, Boxster, and more.
- Direct-fit replacements for road or performance applications.
- Essential for any clutch rebuild or upgrade.
