Ball Bearings
Open bearings dissipate heat more efficiently than shielded and sealed bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Electrically Insulated Ball Bearings
Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently. Shields keep out dust and contaminants.

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.
