Features of Super Smart Ball Sleeve:

• Double ball bearing - matching ball bearing track, providing twice the load capacity
• Even when installed in a slightly non-circular housing, the hard steel outer ring can maintain the assembly diameter of the bearing.
• The bearing disc can swing, rotate, and deflect, providing universal self alignment to compensate for the alignment deviation of the bearing housing.
• The dual edge brush option can prevent contaminants from entering while maintaining lubrication.
