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.
