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

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.

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.

One-Way Locking Ball Bearing Clutches
Internal locking elements (sprags) lock to transmit torque in one direction while turning freely in the other direction. Use them in applications where precision movement is required, such as pick-and-place and automated indexing conveyor systems. Shields keep out dust and contaminants.
Shielded bearings dissipate heat better than sealed bearings, but don’t keep out as much dust.
For dirty or dusty environments, sealed bearings are the best choice, since they block out contaminants better than shielded bearings.
