Genuine OEM Hyundai Crankshaft Thrust Bearing Set, part number 210302B000. This set of precision-engineered bearings is crucial for supporting the crankshaft within the engine block, specifically managing its axial (front-to-back) movement. They reduce friction and prevent excessive play, which is vital for maintaining proper engine operation and longevity. Positioned around the crankshaft's center journal, these metal bearing shells are designed for high-stress environments. Choosing genuine OEM thrust bearings ensures factory-specified tolerances, material composition, and surface finish, which are critical for preventing premature wear, maintaining oil film integrity, and ensuring a long, reliable service life for the engine.
