Low-Profile Mounted Ball Bearings
Designed with a thin, compact housing, these bearings are good for space-constrained applications.
Bearings with steel housing are stronger than bearings with stainless steel and aluminum housings. They are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Sealed bearings block out dust and other contaminants better than shielded bearings.
Bearings with an 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. However, they only work on shafts that spin in one direction.

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.
Set screw shaft-mount bearings secure to shafts when you tighten the set screw, with no need for an additional collar. Set screws cause some amount of marring on shafts.
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.

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.

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