About Ball and Roller Bearings
More
Set Screw Collar Ball Bearings
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.
Bearings with a retaining ring have a removable retaining ring that holds the bearing inside a housing.
Flanged bearings have a flange that ensures proper positioning inside a tube or housing.

One-Piece Thrust Ball Bearings
In addition to handling higher loads than three-piece ball bearings, one-piece bearings are easier to handle. They have an outer band that holds the bearing together and acts as a shield against dust and other contaminants.

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.

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.
Snap optional covers onto bearings to shield them from moisture. Made of polypropylene, they resist corrosion, won’t absorb water, and are FDA compliant.
