About Ball and Roller Bearings

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.

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.
