Looking for a Genuine Toyota Balance Shaft Bearing No.1 (Part No. 11911-28011-02) with guaranteed OEM authenticity and precise fitment? This original factory bearing is engineered to Toyota’s exact specifications and is designed to support the balance shaft assembly with optimal load distribution, smooth rotation, and long-term engine reliability.

The Balance Shaft Bearing No.1 plays a critical role in minimizing engine vibration by maintaining precise balance shaft alignment and reducing rotational friction. Manufactured using high-quality materials and strict tolerance controls, this genuine Toyota bearing ensures stable oil clearance, consistent lubrication, and quiet operation under varying engine speeds and load conditions.

Over time, worn or damaged balance shaft bearings can lead to symptoms such as increased engine vibration, abnormal knocking or humming noises, reduced engine smoothness, and accelerated wear of related internal components. Replacing the bearing with a genuine OEM Toyota part helps restore factory-level refinement and protects the balance shaft and engine block from further damage.

This bearing is designed for direct installation with compatible Toyota engines, ensuring correct seating, alignment, and oil flow without modification. Using the correct OEM part number is essential, as balance shaft bearings require exact dimensional accuracy to function properly within the engine’s internal architecture.

Installing non-genuine or incorrect bearings can result in improper clearances, oil starvation, increased vibration, premature bearing failure, and costly engine repairs. Choosing an original Toyota bearing helps maintain engine integrity, performance, and long-term durability.

Before purchasing, always verify the part number (11911-28011-02), bearing position (Balance Shaft, No.1), and engine compatibility according to your vehicle’s specifications to ensure precise fitment and reliable, factory-approved performance you can trust.
