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.

Thread-Mount Bearings
Combine with threaded pipe to mount these bearings in a variety of positions without the need for a flat mounting surface. Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
NPSM (National Pipe Straight Mechanical) threads are compatible with NPT threads. See more about pipe thread type and sizing.

Flange-Mounted Linear Ball Bearings
The flanged housing makes these bearings a good solution for vertical linear motion applications. All are for use with round end-supported shafts and have a fixed-alignment design for use where shaft misalignment is unlikely. End seals keep lubricant in and dirt out.

Corrosion-Resistant Flange-Mounted Linear Ball Bearings
The bearing, housing, and balls of these mounted bearings are stainless steel for excellent corrosion resistance. The flanged housing is good for vertical linear motion applications. All bearings are for use with round end-supported shafts and have a fixed-alignment design for use where shaft misalignment is unlikely. End seals keep lubricant in and dirt out.
