NISSAN 32264-VB000 Needle Roller Bearing

The genuine OEM Nissan 32264-VB000 needle roller bearing is a precision-engineered, heavy-duty drivetrain component. Needle roller bearings play a critical role in vehicle mechanical assemblies—most commonly in manual transmissions, transfer cases, or differentials—where low-friction, stable rotation of shafts and gears must be ensured within a compact installation space.

Technical Specifications and Construction

• Manufacturer: NISSAN (Genuine OEM part)
• Part Number: 32264-VB000
• Type: Needle Bearing (BEARING-NEEDLE)
• Material Quality: Premium-grade, hardened, and precision-ground bearing steel resistant to high temperatures and continuous mechanical stress.
• Design: Structure featuring thin, cylindrical rollers that deliver outstanding radial load capacity with an extremely low radial cross-sectional height.

Function and Importance

The role of the needle roller bearing is to provide precise radial guidance for rotating components (such as freewheeling gears on transmission shafts). Due to the large contact surface of the needle rollers, the bearing can withstand significant radial loads while minimizing friction loss and heat generation, thereby ensuring smooth and efficient transmission operation.

Typical Symptoms of Wear or Failure

Natural wear of needle roller bearings or improper lubrication (low transmission fluid level, contaminated lubricant) can result in the following issues:

• Abnormal Noises: Humming, rumbling, or whining noises emanating from the transmission that intensify under acceleration or load changes.
• Difficult Gear Shifting: Excessive bearing play or seizure can alter the axial or radial alignment of the gears, preventing smooth gear engagement.
• Metallic Particles in Lubricating Oil: Flaking and spalling (pitting) from the bearing raceways or rollers release fine metal particles into the transmission fluid, risking further damage to adjacent components.

To maintain reliable transmission operation and prevent severe secondary mechanical damage, a worn bearing should be replaced promptly with a genuine OEM part.
