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.

Clamp-On Collar Ball Bearings
Quickly secure these bearings onto shafts with the clamp-on collar for a concentric, mar-free hold. Tighten the single screw on the locking collar around its inner ring on your shaft to center and secure the shaft in the bearing bore. The collar’s firm grip reduces vibration and noise in your system. The steel rings on these bearings have a black-oxide finish for some corrosion resistance.

Washdown Clamp-On Collar Ball Bearings
Designed to stand up to frequent washdowns, you can quickly secure these ball bearings onto shafts with the clamp-on collar in food, beverage, pharmaceutical, and chemical plants. The collar centers your shafts and secures them better than set screw ball bearings, which reduces vibration and noise. To install these bearings, tighten the single screw on the collar around its inner ring on your shaft for a mar-free hold.
Coated with nickel, the steel rings on these bearings won’t corrode from water and harsh cleaners, similar to 304 stainless steel. The inner ring is extended for added shaft support. All of these bearings have NSF registered H1 lubrication, which is certified for incidental contact with food and is suitable for food and beverage applications.

Ultra-Thin Ball Bearings
These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.
Open bearings dissipate heat more efficiently than shielded bearings.
