    Our most precise bearings for tackling radial and thrust loads at once, 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). Choose them for equipment that requires both high speed and pinpoint accuracy, such as machine tool spindles. For example, a bearing on a spindle withstands a radial load as it spins at high speeds and a thrust load when the cutting tool touches the workpiece. These bearings don’t handle as much force from radial loads as standard ones, but you can pair them with a cylindrical roller bearing to increase their load capacity.
    Single Row—Single-row bearings withstand thrust loads from one direction.
    Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.
    Sealed—The best choice for dirty environments. A barrier seals out dust so it won't gunk up or wear down the balls. However, these bearings retain the most heat since air can't flow through.
    Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
