Mounted Ball Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearing with concentric lock use adapter sleeves (sold separately) to lock onto shafts in a way that enables high running speeds with little vibration. They work for applications that require reversing because they allow shafts to rotate in both directions.

Make up for imperfections and gaps between your bearing and shaft for a tight fit. These bearing adapter sleeves are the most common way to mount a bearing with a tapered bore onto a cylindrical seat. They work with both straight and stepped shafts. Secure using the included lock nut.

Compact-Base Mounted Ball Bearings
Also known as tapped-base bearings, these ball bearings mount to surfaces from the bottom through threaded holes. Because of their narrow profile, they’re commonly used in tight-clearance spaces, including systems where multiple shafts are mounted close together.
Concentric lock shaft-mount bearings have a locking collar that centers and secures the shaft in the bearing bore. To install these bearings, tighten the single screw on the locking collar around its inner ring on your shaft. Their firm grip on shafts reduces vibration for quieter operation.

Permanently Lubricated Washdown Compact-Base Mounted Ball Bearings
These bearings are rated IP69K as able to withstand washdown environments such as food, pharmaceutical, and chemical plants. Their fluoropolymer-coated housing is as corrosion resistant as 304 steel and safe for contact with food. The lubrication is NSF registered H1 for incidental contact with food. Because they’re permanently lubricated, these bearings are good for use in hard-to-reach areas or spaces that don’t receive regular maintenance. Also known as tapped base mounted ball bearings, they have threaded holes for fastening through the bottom to secure shafts in tight spaces. Having no mounting bolts on top makes them easier to clean, as well.
Concentric lock shaft mount bearings center and secure shafts in the bearing bore. To install, tighten the single screw on the locking collar around its inner ring on your shaft. By gripping shafts firmly, they reduce vibration in your system for quieter operation.For technical drawings and 3-D models, click on a part number.

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.

Mounted Ball Bearings with Four-Bolt Flange
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
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.

Permanently Lubricated Washdown Mounted Ball Bearings with Four-Bolt Flange
Made to withstand frequent washdowns, these bearings are permanently lubricated, which means you’ll never have to add lubricant. Use them in hard-to-reach areas in food, beverage, pharmaceutical, and chemical plants. With a 316 stainless steel housing, these bearings won’t rust from salt water, chlorine, or chemicals. All are lubricated with NSF registered H1 grease, which is certified for incidental contact with food.
