High-Load Oil-Embedded 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 them to release a thin layer of oil on the bearing’s surface. Color is silver because of the iron. These bearings are also magnetic due to the high iron content.
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.

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.
Iron-copper bearings support heavier loads than 863 iron-copper 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.

Linear Sleeve Bearings
Bearings are for use with round end-supported shafts. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).
Bearings with 0.001" or 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.
Self Aligning—Bearings compensate for shaft misalignment.
PTFE-lined bearings are chemical resistant and nonabrasive. They have a ceramic coating for added corrosion resistance.

To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually). Bearings with 0.001" or 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.
