    About Ball Bearings
    industrial info icon

    Select bearings by load direction, seal type, capacity, and speed ratings to limit wear and keep your equipment running.

    Hex-Bore Ball Bearings

    No need for set screws—the inside corners of these bearings hold them in place on hex shafts as they rotate. They're a good choice when your setup needs to come apart frequently, since there aren't extra mounting steps.
    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.
    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.

    Quick-Mount Ball Bearings

    Set-Screw

    Shaft Mount

    Slip onto a shaft and secure with the turn of a screw. You don't need any special tools to mount these bearings.
    Set-Screw Shaft Mount—Tighten the screws against the shaft to hold the bearing in place. For high-speed applications, consider clamp-on shaft mounts, which are less likely to slip.
    Black-Oxide Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
    Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.
    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.
