About Ball and Roller Bearings
More
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.
Shielded bearings dissipate heat more efficiently than sealed bearings.
Bearings with a retaining ring have a removable retaining ring that holds the bearing inside a housing.

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.
Open bearings dissipate heat more efficiently than sealed bearings.

One-Way Locking Needle-Roller Bearing Clutches

The needles in these bearings roll freely in one direction, but lock to transmit torque when the rotation of the shaft is reversed. Also known as drawn-cup roller clutches. An arrow on the lip indicates the rotational direction that locks the bearings.
Triple-row bearings support radial loads.
Bearings with 301 stainless steel springs handle higher temperatures than bearings with acetal springs.
