    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.
    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.
    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.

    Ball Bearings

    Shielded

    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.
    Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.
    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.

    Shielded

    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.
    Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.
    Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

    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.

    Ball Bearings for Food and Beverage

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

    Sealed

    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.
    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.
    Corrosion-Resistant 440C Stainless Steel—Combine the strength of steel with the corrosion resistance of stainless steel.

    Thrust Ball Bearings

    For silky-smooth motion, the balls inside these bearings roll nearly friction-free. You'll often find them at the end of a shaft or between a stationary and rotating surface, such as on a propeller or rotary table.
    These bearings come as three separate pieces—one cage and two washers. The cage holds the balls in place, while the washers create a surface for the balls to roll on. This design is easy to lubricate, but the oil will attract dust and grime since it's exposed.
    Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
    Stainless Steel—These bearings won't degrade from water or mild chemicals, such as the ammonia in cleaning solutions. However, they're not as strong as steel bearings.

    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.
    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.

    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.
    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.
    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.
    High-Load PEEK—Get the strength of reinforced PTFE without compromising on heat resistance. With no additives, such as polyester fabric, PEEK bearings won’t melt at high temperatures. They’re also nearly as slippery and chemical resistant as plain PTFE.
    High-Load Moisture-Resistant Rulon LR—Won’t swell in wet or humid places, similar to acetal, but can support higher loads. These bearings also operate smoothly from cryogenic to oven-like temperatures.
