About this product
When release bearing performance matters, the Schaeffler LuK 500 0037 20 delivers — built to the same dimensional and material standards as the original part it replaces. Compatible with ALPINA, BMW vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 11 040 131, 11040131, 11 047 231, 11047231 and 21 more. Matching these numbers confirms a like-for-like replacement with no loss of function. Schaeffler LuK is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price. Every part is dispatched with tracked delivery and a 14-day money-back guarantee with hassle-free returns.
release bearing buying guide
Why replace this part?
The clutch release bearing (throw-out bearing) is a ball bearing assembly that slides on the gearbox input shaft guide tube and, when the clutch pedal is pressed, contacts the clutch pressure plate diaphragm spring to disengage the clutch. Although it only contacts the pressure plate during clutch operation, its failure causes noise and complete loss of clutch function. It is always replaced as part of a complete clutch kit.
Signs you need a replacement
- Squealing, chirping, or grinding noise that changes with clutch pedal position
- noise disappears when clutch pedal is fully released or fully depressed
- clutch pedal vibration
- difficulty engaging gears due to incomplete clutch disengagement
- noise worsens progressively over weeks
When to replace
Always replace with the clutch disc and pressure plate — separating these items makes no economic sense given shared labour costs. Typically every 60,000–100,000 miles. Continuous-contact release bearings (common on VAG group vehicles) wear faster as they are always loaded.

How do I know when to replace my release bearing?
Listen for a squealing or rumbling noise that appears when the clutch pedal is depressed and disappears when released. This noise points specifically to the release (thrust) bearing and should not be ignored.
What tools do I need to replace a release bearing?
Tools needed: gearbox jack, circlip pliers (some designs), socket set, clutch input shaft grease. Difficulty: Professional recommended.
