About Ball and Roller Bearings

Angular-Contact Ball Bearings
Open
Sealed
Shielded
The raceways in these bearings are positioned off-center to handle angular (combined radial and thrust) loads.
Double-row bearings handle thrust loads in both directions.
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.
