Slip these bearings onto a shaft and secure with the included set screws, no special tools required. All have an extended inner ring for additional shaft support.
Bearings with a black-oxide steel ring have some corrosion resistance.
Sealed bearings block out dust and other contaminants better than shielded bearings.

Mounted Ball Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with nickel-plated cast iron housing are more corrosion resistant and durable than bearings with a cast iron housing.
Bearings with a set screw secure to shafts without using a collar. They let shafts rotate in both directions, so they’re good for applications where you need to reverse. However, the set screw will leave some marring on the shaft.
Bearings with eccentric lock have a collar that you twist in one direction to grip and the other to release. Compared to bearings with a set screw, they’re easier to install, require less adjustment over time, and are better for high-speed applications. But, they only work on shafts that spin in one direction.

Extra-Clearance Mounted Ball Bearings
![](/prerenderstable/mvPRE/contents/gfx/imagecache/445/4453n21c1-@halfx_1695842907.png?ver=imagenotfound)
Keep shafts, such as those with a shoulder, clear of the mounting surface. These bearings have a higher mounting base that gives them more space to the mounting surface than standard mounting bases. All have a set screw for securing them to shafts without having to use a collar. The screw lets shafts rotate in both directions, so they’re good for applications where you need to reverse.

Washdown Mounted Ball Bearings
Meeting IP69K for washdown environments, these mounted ball bearings are used in food, beverage, pharmaceutical, and chemical plants. All have NSF registered H1 lubrication, which is certified for incidental contact with food and is suitable for food and beverage applications. Made of 316 stainless steel, they resist corrosion and prevent rusting caused by salt water, chlorine solutions, and chemicals.
Set screw bearings secure to shafts as you tighten their screw. They don’t need a collar, but the screw does leave some marring on shafts.
Clamp on bearings have a locking collar to center shafts and secure them better than set screw bearings, so there’s less vibration and noise. To install them, tighten the locking collar’s screw until it grips the inner ring.
Snap optional covers onto bearings to shield them from moisture. Made of polypropylene, they resist corrosion, won’t absorb water, and are FDA compliant.

Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with a set-screw shaft mount secure to shafts with no need for an additional collar. They can be used for bi-directional shaft rotation when applications require reversing action. The set screw may cause some marring on the shaft.
Bearings with an eccentric-lock shaft mount are better than bearings with a set-screw shaft mount for high-speed applications, but only rotate in a single direction.

Permanently Lubricated Washdown Mounted Ball Bearings with Two-Bolt Flange
Permanently lubricated and IP69K certified for washdown environments, these mounted ball bearings are useful for hard-to-reach areas in food, beverage, pharmaceutical, and chemical plants. Mount them using their two-bolt flange. For excellent corrosion resistance and preventing rust caused by salt water, chlorine solutions, and chemicals, their housing is made of 316 stainless steel. All have NSF registered H1 lubrication, which is certified for incidental contact with food and is suitable for food and beverage applications.
Concentric lock bearings have a locking collar to center shafts and secure them better than set screw bearings, so there’s less vibration and noise. Install them by tightening the locking collar’s screw until it presses against the inner ring.
Snap optional covers onto bearings to shield them from moisture. Made of polypropylene, they resist corrosion, don’t absorb water, and are FDA compliant.

These bearings have the highest speed ratings of any mounted ball bearing that we offer. The clamp-on collar creates a 360° grip around the shaft for a strong, mar-free hold. Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.

Mounted Ball Bearings with Four-Bolt Flange
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Set screw bearings secure to shafts as you tighten their screw. They don’t need a collar, but the screw leaves some marring on shafts. Use them in applications where shafts rotate in both directions.
Eccentric lock bearings are quick to install—twist them in one direction to tighten and the opposite to loosen. They’re better than set screw bearings for high speed applications, but they only work with shafts that rotate in one direction.
Concentric lock bearings enable high running speeds while maintaining low levels of vibration; you must pair them with an adapter sleeve (sold separately). They’re good for applications where shafts rotate in both directions.

These bearings have the highest speed ratings of any mounted ball bearing that we offer. The clamp-on collar creates a 360° grip around the shaft for a strong, mar-free hold. Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.

Combine with threaded pipe to mount these bearings in a variety of positions without the need for a flat mounting surface. Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
NPSM (National Pipe Straight Mechanical) threads are compatible with NPT threads. See more about pipe thread type and sizing.
