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.

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.

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.

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.

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.

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.

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.

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.

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.

Easy-Access Mounted Cylindrical-Roller Bearings

Thick, long rollers handle the highest loads of any mounted bearing we offer. Install them with confidence into coal crushers, sludge presses, wood hogs, and other demanding applications. The top lifts off for quick access when you need to install or maintain the shaft. The sturdy housing bolts down to support shafts as they turn.

Lubricate regularly to keep your bearing in tip-top shape, including upon installation. Seals hold lubricant in while keeping dust and contaminants out.

For Radial Loads—Accommodate minor changes in the length of your shaft as it expands and contracts from nearby machinery heat. They're typically positioned away from the drive end in assemblies with long shafts.

For Combined Radial and Thrust Loads—Secure shafts in place and absorb the thrust load. However, these bearings are not designed to handle shafts that expand or contract. They're typically positioned near the drive side of an assembly.

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.

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.

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.

Quick-Mount Ball Bearings for Food and Beverage

Set-Screw Shaft

Mount

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.
