    Ball Bearings

    Image of Product. Front orientation. Ball Bearings. Ball Bearings, Shielded.

    Shielded

    Smoother than smooth—the balls inside these bearings roll nearly friction-free. You’ll often find them on rapidly rotating parts, from the whirring chuck on a power drill to the spinning shaft on an electric motor.
    Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.
    Corrosion-Resistant 440C Stainless Steel—Combine the strength of steel with the corrosion resistance of stainless steel. These bearings won't degrade from water or mild chemicals, such as the ammonia in cleaning solutions. However, they'll weaken when exposed to salt water and harsh chemicals, such as bleach.
    Extended Inner Ring—Connect to mating parts without the need for a spacer. The inner ring juts out farther than the outer ring, so shaft collars and other objects won't touch the bearing's moving parts.
    ABEC Rating—Bearings with an ABEC rating meet industry tolerance standards established by the Annular Bearing Engineers Committee (ABEC). They're rated on a scale from 1 to 9. The higher the rating, the tighter the tolerance. Bearings rated ABEC 1 or 3 are precise enough for most applications. If your application consistently runs at high speeds or requires high accuracy, consider bearings rated ABEC 5 or higher, since they generate less friction and heat.

    Flanged Ball Bearings

    Install these bearings inside a housing and they won't budge. The flange presses against the housing wall, so vibration and other sudden forces parallel to the shaft (thrust loads) won't knock them off-kilter.

    Shielded

    The most precise bearings we offer, with tolerances tighter than a speck of dust. Rated ABEC 7 out of 9, they meet strict tolerance standards established by the Annular Bearing Engineers Committee (ABEC). You'll find them in equipment that requires both high speed and pinpoint accuracy, such as gyroscopes.
