A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

With a spherical raceway and two rows of balls, these bearings compensate for shaft misalignment.
Open bearings dissipate heat more efficiently than sealed bearings.
