Extreme-Load Tapered-Roller Thrust Bearings

With thick, tapered rollers, these thrust bearings are the strongest we offer. The rollers spin inside a raceway instead of a cage, so there’s room for more rollers to support higher loads than three-piece designs. You’ll often find them on crane hooks and kingpins that connect semi-trailers to semi-tractors. However, they rotate at a fraction of the speed of other roller thrust bearings.

Since they come as one piece, you don’t need to assemble cages and washers to install. An outer band holds the rollers inside the raceway, keeping lubricant in and dirt out.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

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. In addition to a band, these bearings also have a rubber seal to block dust from creeping in and wearing down the rollers. However, they retain the most heat since air can’t flow through.

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.

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.

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.

Needle-Roller Bearings

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.

Oil-Embedded Flanged Sleeve Bearings

Install and forget these self-lubricating bearings. All are made from porous metal and saturated with oil to reduce maintenance and downtime. A good all-around choice, they are used in everything from palm-sized fans in electronics to tire-sized pulleys. Although these bearings will work in most conditions, oil may drip away if temperatures get too high. Consider a graphite-lubricated bearing for higher temperatures or places where you can’t afford the mess. All are fabricated, lubricated, and inspected in the U.S.

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.

841 Bearing Bronze—A classic choice for a starter pick. Also known as SAE 841 bearings.

High-Load 863 Iron Copper—Iron makes these bearings harder, stronger, and more resistant to sudden starts and stops than 841 bearing bronze. However, they operate at slower speeds. The increased iron content makes these bearings appear silver.

Extreme-Load Heat-Treated Iron Copper—Our strongest oil-embedded flanged sleeve bearings. They’re heat treated to form a uniform internal grain that makes them stronger than 863 iron copper. As a result, they’re often used to support extreme loads in earth-moving equipment and railroad applications. The increased iron content makes these bearings appear silver.

Mineral Oil Base—Mineral oil consistently lubricates at most temperatures but doesn’t last as long as synthetic 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.

Mounted Ball Bearings

Smoother than smooth—the balls inside these bearings roll nearly friction-free. The sturdy housing bolts down to support shafts as they turn.

Lubricate regularly to keep your bearing in tip-top shape. Bearings with seals and shields keep lubricants in and contaminants out, and come packed with grease. Open bearings require initial lubrication and offer less protection against dust and debris.

Nickel-Plated Cast Iron Housing—Combine the strength of iron with the corrosion resistance of stainless steel at an affordable price point. Nickel-plated iron is also unlikely to chip.

Set Screw—Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.

Ultra-Low-Friction Oil-Embedded Flanged Sleeve Bearings

Our slipperiest metal bearings, these are ideal for machinery with frequent starts and stops, such as conveyors. With nonstick PTFE particles added to the oil, they reduce friction to minimize wear and heat, so equipment runs more efficiently and lasts longer. All are fabricated, lubricated, and inspected in the U.S.

Easy-Adjust Mounted Ball Bearings with Two-Bolt Flange

Change the position of your bearing without having to remove your shaft. Just loosen the bolt in the elongated mounting hole for quick adjustments. The housing mounts in place with a two-bolt flange, the most common type of flanged bearing. Inside, the balls roll nearly friction-free to support smooth rotation.

Lubricate regularly to keep your bearings in tip-top shape. These bearings come packed with grease and sealed to block out dust and contaminants.

Powder-Coated Cast Iron Housing—A rugged iron base coated in thick powder that protects against water, mild detergents, and oil. However, if the coating is scratched or chipped, the underlying iron may rust.

Set Screw—Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.

Flanged Sleeve Bearings

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.

High-Load 932 Bearing Bronze—These bearings are strong enough for sudden starts and stops, plus they resist wear and tear. They are cast from an alloy of leaded tin bronze for uniform rigidity and strength. Also known as 660 leaded bronze bearings.

Oil-Embedded Thrust Bearings

Our simplest-to-use thrust bearings, with no moving parts and no need to lubricate. Their porous surface releases oil over time, so you can install and forget them. While they run in most conditions, oil may drip away if temperatures climb too high. For extremely hot environments, consider graphite-lubricated bearings. All are fabricated, lubricated, and inspected in the U.S.

Dry-Running Metal-Reinforced Plastic Thrust Bearings

Combine naturally slippery PTFE with the strength of metal. These bearings don't need lubricant, so there's no oil to maintain, drip off, or attract dust.

Mounted Ball Bearings with Three-Bolt Flange

Smoother than smooth—the balls roll nearly friction-free within a sturdy housing to support shafts as they turn. A good choice for tight spaces, these bearings mount with a three-bolt flange that only requires access from one side during installation.

Lubricate regularly to keep your bearing in tip-top shape. These bearings come packed with grease and sealed to block out dust and contaminants.
