    Ball Bearings

    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.
    Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
    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.

    Electrically Insulating Ball Bearings

    Shielded

    Protect bearings from stray currents. The ceramic balls insulate bearings from electrical charges in electric motors and power generators that can damage the inner ring over time. The balls also generate less heat than metal ones, so you don’t have to lubricate them as often to keep bearings running smoothly.
