This genuine Porsche Needle Cage (Part No. 99920147000 / 999-201-470-00) is an original equipment transmission bearing designed and manufactured to Porsche’s exact factory specifications. This durable needle roller bearing assembly is used inside the manual gearbox to support critical rotating shafts, ensuring smooth transmission operation.
Fits:
Porsche 911 1974 - 1986 4 & 5 speed
Diagram Ref no 7.
This needle cage bearing functions as a rolling element bearing within the manual transmission. Specifically, it serves to:
• Support and guide rotating transmission shafts under load
• Reduce friction and wear between metal components
• Maintain alignment of gears and shafts for smooth shifting
• Minimise transmission noise and heat build-up during operation
A needle cage typically houses many small cylindrical rollers that distribute load over a larger surface area than a plain bearing, which enhances durability and reduces friction in high-speed, high-load gearbox environments.
Function
• Friction Reduction: Needle rollers reduce surface contact friction between rotating components.
• Load Handling: Supports radial loads within the transmission at critical gear positions.
• Smooth Operation: Promotes precise and efficient gear movement with minimal resistance.
• Long Service Life: Engineered to resist wear and maintain structural integrity under continued transmission stresses.
Transmission bearings like this needle cage are critical to the longevity and smooth operation of a manual gearbox. Without proper bearing support, shafts can wear prematurely, gears can grind, and shifting can become rough or imprecise. A genuine Porsche OE bearing offers the correct hardness, dimensional tolerances, and roller design — ensuring the transmission operates as it did when new.
Replace this bearing if you notice:
• Unusual gearbox noise, especially when changing gears
• Rough or notchy shifting feel
• Vibration or unusual resonance from the transmission
• Sluggish gear engagement
• During full gearbox rebuild or overhaul
