Precision Stainless Steel Ball Bearings
Made to tight tolerances, these 440C stainless steel bearings combine speed and accuracy with corrosion resistance.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Flanged Ball Bearings
The flange ensures proper positioning inside a tube or housing.

Oil-Embedded Sleeve Bearings
Startup friction causes these 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.

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.

High-Load Oil-Embedded Flanged Sleeve Bearings
Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes these bearings to release a thin layer of oil onto their surface. Color is silver because of the iron.
863 iron-copper bearings are also known as Super 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.
