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.

Steel and 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.

Oil-Embedded 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.

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

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.

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.

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.

Sealmaster—Famous for exceptional sealing, Sealmaster bearings include a signature three-part seal in the inner ring. This design blocks out gritty debris and purges old grease to extend the life of the bearing.

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.

Light Duty Mounted Ball Bearings

With a two-piece housing made from thin pressed metal, these bearings are a cost-effective option when extreme precision isn't necessary. Less stable than bearings with forged, one-piece housings, they're good for hand-cranked systems, gravity feed conveyor rollers, and other low-speed applications. Inside, the balls roll nearly friction-free to support smooth rotation.

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

Steel Housing—Best for dry environments as moisture will cause them to 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.

Eccentric Lock—An off-center opening wedges against the shaft to grip it as it turns. Eccentric locks won't mar the shaft like a set screw, but the shaft will only rotate in one direction, so they aren't suitable for applications where the load will be reversed.

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.

One-Piece Thrust Ball Bearings

No need to assemble cages and washers—these thrust ball bearings come as one piece for easy installation. The balls spin inside a raceway instead of a cage, so there's room for more balls to support higher loads than three-piece bearings. An outer band holds the balls 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.

Mounted Ball Bearings with Four-Bolt Flange

Smoother than smooth—the balls inside these bearings roll nearly friction-free. The four-bolt flange supports shafts with a stronger connection to the mounting surface than two-bolt alternatives.

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

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.

841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.

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. Backed with steel, they're as strong as other all-metal thrust bearings. However, they're best for dry environments since moisture will cause the steel to rust.

Tight-Clearance Thrust Ball Bearings

Save space around your shaft—set the end of your shaft vertically on top of these bearings instead of inserting it through. They work similar to miniature turntables, so you can even use them to precisely rotate equipment. Fastened by a center rivet, these bearings don’t require you to assemble cages and washers like three-piece designs. They have thick washers, deeply grooved raceways, and oversized balls to support higher loads than bearings of the same size. The balls are exposed, which makes them easy to lubricate, but the oil may attract dust and grime.

Hub-Mount Screw-Clamp Bushings

Transfer torque directly from a shaft to a hub. These bushings install over your hub to mount a sprocket, pulley, or gear to a shaft at the same time. Common in industrial gearbox applications, they can also connect a hollow shaft over a solid shaft. As screw-clamp bushings, they're good for shock loads. When you tighten the included clamping screws, the outer rings compress against a sprocket, pulley, or gear in between them, causing the inner rings to tighten around the shaft.
