    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.
    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.
    Highly Corrosion-Resistant 316 Stainless Steel—The most corrosion-resistant metal bearings we offer. They won't pit or weaken from salt water or harsh chemicals, such as bleach and chlorine found in cleaning solutions.
    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.

    Dry-Running Ball Bearings

    Image of Product. Front orientation. Ball Bearings. Dry-Running Ball Bearings.
    Made of naturally slippery plastic so there's no lubricant to maintain or make a mess. These bearings are ideal for spic-and-span spaces since oil won't drip off, wash out, or collect dust over time. They won't rust or warp from moisture, so they stand up to thorough cleanings.
    Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, reducing wear and extending the life of the bearing.
    Acetal—The most common choice for plastic bearings, acetal is economical yet still stands up to daily wear and tear.
    High-Temperature Chemical-Resistant PEEK—The most heat- and chemical-resistant plastic bearings we offer. Even inside autoclaves as hot as 330° F, PEEK won't melt. It also won't degrade when exposed to harsh acids and bases.
    316 Stainless Steel Balls—Won't corrode from salt water or harsh chemicals, such as bleach and chlorine found in cleaning solutions.
    Glass Balls—Nonmagnetic, so they won't interfere with sensors and other sensitive electronics.

    Dry-Running Flanged Ball Bearings

    Open

    Don't risk your bearing popping out of place or making a mess. The flange presses against the housing wall, so vibration and other sudden forces parallel to the shaft (thrust loads) won't knock these bearings off-kilter. Made of naturally slippery plastic, there's no lubricant to maintain. No lubricant means no oil that could drip off, wash out, or collect dust, so they're ideal for spic-and-span spaces. They stand up to thorough cleanings since they won't rust or warp from moisture.

    Ball Bearings for Food and Beverage

    Image of Product. Front orientation. Ball Bearings. Ball Bearings for Food and Beverage, Open.

    Open

    Food production rolls along smoothly on these bearings. Greased with FDA-compliant lubricant, they’re safe to install on food-processing equipment, such as conveyor belts, so long as they don’t directly touch the food. The 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.
    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.

    High-Load Dry-Running Ball Bearings

    Image of Product. Front orientation. Ball Bearings. High-Load Dry-Running Ball Bearings.
    Double the balls for double the load capacity—these bearings carry twice as much weight as standard dry-running ball bearings. Made of naturally slippery plastic, there's no lubricant to maintain. No lubricant means no oil that could drip off, wash out, or collect dust, so they're ideal for spic-and-span spaces. They stand up to thorough cleanings since they won't rust or warp from moisture.

    Shims for Ball Bearing Housings

    Image of System. Front orientation. Exploded view. Contains MultipleImages. Shims. Round, For Ball Bearing Housings, Sold Individually.
    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.
