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 Thrust 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.

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.
Sealed bearings block out dust and other contaminants.
