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.

These bearings have the highest speed ratings of any mounted ball bearing that we offer. The clamp-on collar creates a 360° grip around the shaft for a strong, mar-free hold. Bearings are self-aligning to compensate for shaft misalignment.

Bearings with torque indicator tell you when the shaft is centered, ensuring smooth rotation in applications with high vibration.

Shielded bearings dissipate heat more efficiently than sealed 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.

316 stainless steel bearings resist corrosion and prevent rusting caused by salt water, chlorine solutions, and chemicals. Snap optional covers onto bearings to shield them from moisture. Made of polypropylene, they resist corrosion, won’t absorb water, and are FDA compliant.

Polymer-coated cast iron bearings are also known as tapped-base mounted ball bearings. They require access to the underside of the mounting surface.

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.

Use these UHMW bearings in wet, corrosive environments.

Bearings with UHMW housing are made of a single UHMW polyethylene block. They have good vibration-damping qualities.

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

Bearings with a set-screw shaft mount secure to shafts with no need for an additional collar. They can be used for bi-directional shaft rotation when applications require reversing action. The set screw may cause some marring on the shaft.

Bearings with an eccentric-lock shaft mount are better than bearings with a set-screw shaft mount for high-speed applications, but only rotate in a single direction.

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.
