    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.
    Polyester Plastic Housing—Lightweight and naturally rust-resistant, with a smooth surface that's easy to wipe clean.
    Aluminum Housing—One-third the weight of cast iron but not as strong. Aluminum also resists corrosion.
    Press Fit—For a tight connection to the shaft, install with a press or by heating and then cooling the bearing. Also known as an interference fit.
    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.
    Locknut—Tighten the nut for a strong hold that stands up to heavy vibrations without letting go. An adapter sleeve is required and sold separately.
    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.

    Mounted Ball Bearings with Four-Bolt Flange

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. 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.
    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.
    Polyester Plastic Housing—Lightweight and naturally rust-resistant, with a smooth surface that's easy to wipe clean.
    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.
    Locknut—Tighten the nut for a strong hold that stands up to heavy vibrations without letting go. An adapter sleeve is required and sold separately.
    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.

    Mounted Ball Bearings with Two-Bolt Flange

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. Mounted Ball Bearings with Two-Bolt Flange.
    Smoother than smooth—the balls inside these bearings roll nearly friction-free. The sturdy housing supports the shaft and secures with a two-bolt flange, the most common type of flanged bearing.
    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.
    Polyester Plastic Housing—Lightweight and naturally rust-resistant, with a smooth surface that's easy to wipe clean.
    PEEK Housing—PEEK resists harsh chemicals and won’t melt or deform at high temperatures. These housings are highly wear-resistant, but they may crack or dent from hard impacts and vibrations.
    Press Fit—For a tight connection to the shaft, install with a press or by heating and then cooling the bearing. Also known as an interference fit.
    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.

    Light Duty Mounted Ball Bearings with Two-Bolt Flange

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. Light Duty Mounted Ball Bearings with Two-Bolt Flange.
    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. The balls inside roll nearly friction-free to support smooth shaft rotation. The housing mounts in place with a two-bolt flange, the most common type of flanged bearing.
    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.
    303 Stainless Steel Housing and 304 Stainless Steel Housing—Prevent rust from exposure to moisture and mild chemicals, including ammonia-based cleaning solutions.
    Press Fit—For a tight connection to the shaft, install with a press or by heating and then cooling the bearing. Also known as an interference fit.
    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.

    Light Duty Mounted Ball Bearings

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. 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.
    304 Stainless Steel Housing—Prevent rust from exposure to moisture and mild chemicals, including ammonia-based cleaning solutions.
    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.

    Mounted Tapered-Roller Bearings

    Support heavier loads than mounted ball or needle-roller bearings, but at lower speeds. These bearings also withstand thrust loads, which are forces acting parallel to the shaft. The sturdy housing bolts down to support shafts as they turn.
    Lubricate your bearings regularly to keep them 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.
