    Mounted Ball Bearings

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. 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.
    Clamp On—Tighten the clamping screw to close the collar around your shaft for a secure, mar-free grip. The collar centers the shaft, decreasing vibration and allowing for higher speeds than set screws. Also known as concentric lock bearings.
    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.
    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.
    SKF—Manufactured in Europe with a strong focus on precision. The more precise the bearing, the more efficiently it will run.
    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.

    Swap out worn inserts instead of replacing the entire mounted unit. To choose an insert, match the manufacturer model number on your existing bearing.
    Set-Screw Shaft Mount—Tighten the screws against the shaft to hold the bearing in place, regardless of the direction the shaft spins.
    Eccentric-Lock Shaft Mount—Twist the collar one way to tighten these bearings and the other way to loosen. They're a good choice when you need to take your setup apart frequently. However, they only turn one way, so they won't work with shafts that reverse.
    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.

    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.
    Clamp-On Shaft Mount—The clamp tightens around the shaft for a strong 360° grip. These mounts attach more securely than set screws to reduce vibration. Plus, there aren't any screws pressing into the shaft, so it stays free from damage. Also known as a concentric lock.
    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.

    Image of Product. Front orientation. Mounted Bearings. Food-and-Beverage Mounted Ball Bearings with Four-Bolt Flange.
    With NSF-registered H1 grease, these bearings are safe for use on food and beverage lines. Install them into conveyors, packaging systems, and other food processing applications where contact with ingredients is rare but possible. The balls roll nearly friction-free within a sturdy housing to support shafts as they turn. The four-bolt flange creates a stronger connection to the mounting surface than two-bolt alternatives.
    Lubricate your bearings regularly to keep them in tip-top shape. These bearings come packed with grease and sealed or shielded to block out dust and contaminants.
    Plastic Housing—Lightweight and naturally rust-resistant, with a smooth surface that's easy to wipe clean.
    316 Stainless Steel Housing—The most corrosion-resistant metal we offer, these housings hold up to harsh chemicals and salt water.
    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.
    Closed Caps—Mount on the end of the shaft to block out debris and prevent accidental contact with rotating parts.
    Open Caps—Install anywhere along the shaft to block out debris and prevent accidental contact with rotating parts.

    High-Temperature Graphite-Lubricated Sleeve Bearings

    Image of Product. Front orientation. Sleeve Bearings. High-Temperature Graphite-Lubricated Sleeve Bearings.
    Made of a graphite and metal alloy, these bearings stay slippery at high temperatures where oil burns off and other bearings fail. With no need for refills, they require little to no maintenance. You’ll find them in pumps, propellers, and mixers that spin near steam or inside ovens. However, graphite may eventually flake off, dropping flecks and leaving smudges. If you need a spic-and-span space, consider dry-running bearings made of slippery plastic instead. 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.
    Extreme-Temperature Chemical-Resistant Graphalloy—From the freezer to the furnace, these bearings glide in extreme temperatures where other bearings grind and fail. They resist decay caused by the strong acids or bases found in cleaning fluids. They even work underwater without swelling or warping.

    Permanently Lubricated Mounted Ball Bearings

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. Permanently Lubricated Mounted Ball Bearings.
    Reduce upkeep with bearings that never need lubrication. Inside, an oil-infused solid polymer fills the spaces between the balls to keep them rolling nearly friction-free. The polymer releases the optimal amount of lubricant on startup—never too much or too little. The embedded oil never leaks out, and seals keep dust and contaminants from sneaking in. The sturdy housing bolts down to support shafts as they turn.
    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.

    You don't need any special tools to install these bearings in food production areas. Slip them onto a shaft and secure with the turn of a screw for easy mounting. Greased with NSF-registered H1 lubricant, these bearings are safe to install on food-processing equipment, such as conveyor belts, so long as they don’t directly touch the food. They're IP69K rated, so they'll stand up to the hot water from a pressure washer when cleaning your facility at the end of the day.
    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.
    Corrosion-Resistant Nickel-Plated Steel—These bearings resist mild chemicals, such as the ammonia in cleaning solutions, while maintaining the strength of steel. The nickel coating can wear or chip over time, though. If it does, the steel beneath will rust quickly.
    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.

    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.

    Reduce upkeep on your food line with bearings that never need lubrication. On startup, an oil-infused solid polymer releases the optimal amount of food-safe, NSF-registered lubricant—never too much or too little. The embedded oil never leaks out, and seals keep dust and contaminants from sneaking in. Install them into conveyors, packaging systems, and other food processing applications where contact with ingredients is rare but possible. The balls roll nearly friction-free within a sturdy housing to support shafts as they turn. The four-bolt flange creates a stronger connection to the mounting surface than two-bolt alternatives.
    316 Stainless Steel Housing—The most corrosion-resistant metal we offer, these housings hold up to harsh chemicals and salt water.
    Clamp On—Tighten the clamping screw to close the collar around your shaft for a secure, mar-free grip. The collar centers the shaft, decreasing vibration and allowing for higher speeds than set screws. Also known as concentric lock bearings.
    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.

    Lift the top off to install, inspect, and maintain your shaft without full disassembly. Inside, the sleeve is made from babbitt, a tough, corrosion-resistant alloy. With no moving parts, sleeve bearings stand up to dusty, dirty environments better than ball or roller bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing bolts down to support shafts as they turn.
    Lubricate regularly through the housing's lubrication port to keep your bearing in tip-top shape. The grooves help to evenly distribute lubrication across the bearing's surface.

    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.

    A mounting flange prevents movement during tightening. These bushings are good for shock loads. When you tighten the included screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.

    The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered sprockets and pulleys of the same bushing trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
