    Ball Bearings

    Image of Product. Front orientation. Ball Bearings. Ball Bearings, Open.

    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.

    Flanged Ball Bearings

    Image of Product. Front orientation. Ball Bearings. Flanged Ball Bearings, Open.

    Open

    Install these bearings inside a housing and they won't budge. The flange presses against the housing wall, so vibration and other sudden forces parallel to the shaft (thrust loads) won't knock them off-kilter.
    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.
    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.

    Bearing

    Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
    Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.
    Sealed Bearing—Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.
    Shaft Liners—Shaft liners allow you to use the bearing on unhardened and unground shafts.

    Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.

    Dry-Running Flanged Sleeve Bearings

    Image of Product. Front orientation. Contains Annotated. Flanged Sleeve Bearings. Dry-Running Flanged Sleeve Bearings.
    Made of naturally slippery plastic so you’ll never have to add lubricant. They’re ideal for clean environments where you need to prevent oil drips or graphite flakes. Compared to metal bearings, they are lighter and will never rust.
    Flanged sleeve bearings combine a sleeve and thrust bearing in one. The flange supports thrust loads and prevents the bearing from being pushed out of place. The sleeve is the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.
    Nylon—The most popular choice, nylon is wear resistant yet economical. Keep in mind, though, that it will swell and weaken when exposed to moisture.
    MDS-Filled Nylon—A step up from standard nylon bearings. Upgraded with fine particles of molybdenum disulfide (MDS), these bearings have extra lubricity and wear resistance. However, they’re still nylon, which will swell and weaken when exposed to moisture.
    Moisture-Resistant Acetal—These bearings won’t warp or swell from humidity or direct contact with water, unlike nylon.
    Ultra-Chemical-Resistant PTFE—The most chemical-resistant bearings we offer. PTFE is unaffected by the harsh fluids that other plastics can't handle, including all strong acids and bases. PTFE also reduces friction better than nylon but is not as strong.

    Vibration-Damping Oil-Embedded Sleeve Bearings

    Image of Product. Front orientation. Sleeve Bearings. Vibration-Damping Oil-Embedded Sleeve Bearings.
    These bearings quiet equipment by absorbing vibration. The rubber layer on the inside of these bearings flexes to align the shaft and reduce rattling. The bronze core is made from porous metal and saturated with oil to reduce maintenance and downtime. They’re used in compressors, engine mounts, and other vibrating equipment that suddenly starts and stops.
    With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.
    841 Bearing Bronze with 304 Stainless Steel Shell—The choice for most wet locations. These bearings won't corrode after washdowns and can stand up to most detergents and oil.
    Synthetic Oil Base—A high-quality lubricant makes all the difference. Synthetic oil is less sensitive to temperature changes than mineral oil, so it won't get runny and leak away at higher temperatures.

    These bearings don’t come with a lubricant, so you can select the oil that meets the needs of your application. You’ll need to refill the oil, so make sure the bearing is located where you can access it. All are fabricated and inspected in the U.S.
    With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.
    High-Load Chemical-Resistant 954 Bearing Bronze—The strongest of our bronze bearings. The addition of iron and aluminum makes them exceptionally strong and resistant to chemicals. They’re often used in the most demanding environments, such as salt mines. Also known as aluminum bronze.
