NISSAN 32223-0T200 Main Shaft Needle Roller Bearing

The genuine Nissan 32223-0T200 countershaft / main shaft needle roller bearing (BRG MAIN SHAFT) is a critical precision component of the manual transmission's internal assembly. This bearing ensures stable, minimal-friction rotation of the transmission shafts, directly contributing to smooth gear shifting and efficient drivetrain operation.

Technical Features and Functions:

• Heavy-duty design: The needle roller construction provides an exceptionally high radial load capacity within a minimal installation envelope, which is essential in a compact transmission housing.
• Premium material quality: Manufactured to stringent OEM standards from hardened bearing steel that withstands high operating temperatures and continuous mechanical stress.
• Optimized lubrication: Designed to allow transmission fluid to circulate effectively through the rollers, minimizing frictional heat and premature wear.

Common Symptoms of Bearing Wear or Failure:

• Abnormal noises: Whining, growling, or metallic friction sounds from the transmission that may change when pressing or releasing the clutch pedal.
• Vibration: Noticeable vibrations felt through the gear shift lever or the vehicle floor pan during driving.
• Difficult shifting: Inaccurate or stiff gear engagement caused by improper shaft positioning.
• Metal particles in the gear oil: Presence of tiny metal flakes from surface fatigue (pitting) on the raceways or rollers observed during an oil change.

Replacing internal transmission bearings requires advanced technical expertise. Using genuine Nissan parts guarantees a perfect fit and restores factory performance.
