Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Permanently Lubricated Stainless Steel Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

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.

Light Duty Dry-Running Sleeve Bearings
Use where high loads and speeds are not required.
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.
For technical drawings and 3-D models, click on a part number.
Oil-Embedded Flanged Sleeve Bearings
Startup friction causes these bearings to release a thin layer of oil on the bearing’s surface. They’re flanged, so they handle loads both parallel and perpendicular to the shaft. They’re 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.
