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.

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.

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.

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.

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.

Food-and-Beverage Mounted Ball Bearings

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 smooth rotation.

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.

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.

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.

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.

Thread-Mount Ball Bearings

Smoother than smooth—the balls roll nearly friction-free inside a sturdy housing to support shafts as they turn. A good solution when you lack flat mounting surfaces, these bearings mount directly onto the ends of threaded pipe. Just twist to tighten and mount them in a variety of positions.

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