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.

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.

Spherical-Roller Bearings
Two rows of rollers give these bearings dynamic radial load capacities over five times higher than comparably sized tapered-roller bearings. Also known as rock crusher bearings, they handle heavy shock loads and are used for metal milling machinery, mining and oil field equipment, and in paper mills.

Needle-Roller Bearings
Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.
Sealed bearings block out dust better than open bearings, but retain more heat.

Precision Needle-Roller Bearings
Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
Open bearings dissipate heat more efficiently than sealed bearings.
Shaft liners allow you to use the bearing on unhardened and unground shafts.

High-Speed Mounted Ball Bearings
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.
Sealed bearings block out dust and other contaminants better than shielded bearings.

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.
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.
