About Ball and Roller Bearings

Mounted Ball Bearings with Four-Bolt Flange
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.
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.

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.
Set-screw bearings secure to shafts as you tighten their screw. They don’t need a collar; however, the screws leave some marring on the shaft.
Concentric-lock bearings have a collar that centers and secures the shaft in the bearing bore. To install, tighten the single screw on the collar around its inner ring on your shaft. These bearings have a secure grip on the shaft that reduces vibration and noise.

Food Industry Mounted Ball Bearings with Four-Bolt Flange
The lubricant in these mounted ball bearings is suitable for incidental contact with food. Bearings are self-aligning to compensate for shaft misalignment.
Steel bearings are stronger than stainless steel bearings, but not as corrosion resistant.
Stainless steel bearings are more corrosion resistant than steel bearings.
Sealed bearings block out dust and other contaminants better than shielded bearings.
Shielded bearings dissipate heat more efficiently than sealed bearings.

Mounted Sleeve Bearings with Four-Bolt Flange
Capable of handling temperatures from -400° to 750° F, these graphalloy bearings have the widest temperature range of any of our mounted bearings. They are self-aligning to compensate for shaft misalignment.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Washdown Mounted Ball Bearings with Four-Bolt Flange
Meeting IP69K for washdown environments, these mounted ball bearings are used in food, beverage, pharmaceutical, and chemical plants. They have excellent corrosion resistance and prevent rusting caused by salt water, chlorine solutions, and chemicals because their housing is 316 stainless steel. All have USDA H1 approved lubrication, which is certified for incidental contact with food and is suitable for food and beverage applications.
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.
