Self-Aligning Ball Bearings
Open
Sealed
With a spherical raceway and two rows of balls, these bearings compensate for shaft misalignment.
Open bearings dissipate heat more efficiently than sealed bearings.
Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.
