    Ball Bearings

    Open

    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.
    Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.
    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.

    Permanently Lubricated Ball Bearings

    Image of Product. Front orientation. Ball Bearings. Permanently Lubricated Ball Bearings.
    Install and forget these self-lubricating bearings. Their lubricant is a solid material that fills the space between the balls and releases oil over time, so you'll never need to add more.
    Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.
    Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
    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.
    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.

    Shims for Ball Bearing Housings

    Image of System. Front orientation. Exploded view. Contains MultipleImages. Shims. Sold Individually, For Ball Bearing Housings, Round.
    No need for keys, pins, or messy adhesives. These shims fit around the outer ring of your bearings for a secure hold in stamped, molded, or worn housings. All have ridges that press against the housing like a spring to keep the bearings in place. The ridges also dampen vibration for smooth operation, adjust for temperature fluctuations to maintain their grip, and compensate for up to 0.5° of misalignment. These shims are also known as tolerance rings.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these shims resist rust. However, they’ll corrode or pit when exposed to salt water and chemicals.
