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.

Oil-Embedded Sleeve Bearings
Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Needle-Roller Thrust Bearings
Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings. Because of the large contact area between the rollers and washers (not included), these bearings are great for medium to heavy duty, low-friction jobs. For use on hardened and ground surfaces.
Washers allow you to use the bearing on unhardened and unground surfaces.
