Information
Needle roller bearing.
This needle roller bearing, also known as a needle cage bearing, is used in the Porsche 915 type manual transmission. In the gearbox, needle roller bearings support and permit rotation of internal components by minimizing friction between moving parts.
Fits:
Porsche 911 1974 - 1986 4 & 5 speed
Diagram Ref no 7.
This OE Match version meets original specification dimensions and tolerances to ensure proper fit and function when replacing worn or damaged bearings.
The needle roller bearing provides smooth rotational support for transmission shafts and gears. It helps reduce friction and wear between the main shaft and the transmission housing or gear assemblies, allowing gearsets to spin freely and reliably under load. This results in consistent gear engagement, reduced drivetrain stress, and a smoother shifting experience.
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.
Over time, the original needle roller bearings can become worn, leading to increased friction, gear noise, and premature wear of transmission components. A failing bearing may cause rough shifting, gear chatter, or accelerated gearbox wear. Replacing the worn bearing with an OE Match part ensures proper internal support, restores smooth gearbox operation, and helps protect more expensive transmission components from damage.
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

- Severe gearbox damage if bearing failure progresses.
Why Replacement Matters:
- The flywheel-end shaft bearing operates under constant rotational loads and is subjected to significant torque forces, heat and vibration throughout its service life. Over time, bearing surfaces can wear, lubrication can deteriorate and internal clearances can increase, reducing the bearing's ability to support the pinion shaft accurately.
- A worn bearing can allow excessive shaft movement, affecting gear mesh accuracy and placing additional stress on gears, synchronisers and other internal transmission components. If left unresolved, bearing failure can lead to accelerated gearbox wear, increased noise and potentially extensive transmission damage requiring a full rebuild.
- Replacing a worn flywheel-end shaft bearing restores correct shaft support, improves gearbox smoothness and helps protect valuable transmission components from premature wear.

A cylindrical roller bearing is a precision internal gearbox component designed to support rotating transmission shafts while allowing them to operate with minimal friction. Unlike a conventional ball bearing, it uses cylindrical rollers to provide a relatively large contact area between the rolling elements and bearing races, making this bearing type particularly well suited to carrying significant radial loads.
Inside a gearbox, accurate shaft support is critical. Gears must remain correctly positioned relative to one another so their teeth mesh as intended. Excessive bearing wear can allow unwanted shaft movement, potentially resulting in noise, vibration, poor gear engagement and accelerated wear of other transmission components.
This OE Match Gearbox Cylindrical Roller Bearing provides a high-quality replacement for a worn or damaged original bearing during gearbox repair, overhaul or restoration.
What This Product Does:
- Supports a rotating shaft within the gearbox.
- Carries radial loads generated during transmission operation.
- Allows the supported shaft to rotate with low friction.
- Helps maintain accurate shaft alignment.
- Helps maintain correct gear positioning and mesh.
- Reduces unwanted movement within the transmission.
- Supports smooth gearbox operation.
- Helps distribute loads through the bearing surfaces.
- Contributes to reliable transmission operation under varying loads.
- Helps prevent excessive shaft movement.
- Replaces a worn, noisy or damaged gearbox bearing.
- Provides an OE Match replacement for compatible Porsche transmissions.
Symptoms Of Wear Or Failure:
- Whining from the gearbox.
- Rumbling or growling noises.
- Grinding noises from the transmission.
- Noise that changes with road speed.
- Noise that changes depending on the selected gear.
- Increased gearbox vibration. Excessive transmission shaft play.
- Difficult or inconsistent gear selection. Gear lever vibration.
- Transmission noise under acceleration.
- Noise becoming more noticeable on overrun.
- Metallic particles found in the gearbox oil.
- Visible wear or pitting on the bearing surfaces.
- Damaged cylindrical rollers.
- Discolouration caused by excessive heat.
- Roughness when rotating the bearing by hand during overhaul.
- Excessive internal bearing clearance.
- Damage discovered during gearbox disassembly.
Why Replacement Matters:
- Transmission bearings maintain the precise relationship between shafts, gears and other rotating components.
- As a bearing wears, its internal clearances can increase. This can allow the supported shaft to move beyond its intended position. Even relatively small amounts of unwanted movement can affect how transmission gears engage and transfer load.
- A deteriorating bearing may initially produce only a faint whine or rumble. As wear progresses, vibration and shaft movement can increase and place additional loads on neighbouring gearbox components.
- Replacing a worn OE Match Cylindrical Roller Bearing during the early stages of deterioration can help prevent a relatively contained bearing repair from developing into a more extensive gearbox rebuild.
