    High-Strength Replacement Bearings

    Sealed Power A-Series engine bearings have a small percentage of silicon mixed in with the aluminum and tin that make up the bearing-surface alloy. The silicon resists wear while polishing the journals of a crank surface during operation. A bored Micro-groove design helps to minimize debris embedding, which can score the crank's surface.
