What Is Sealed Ball Bearing?

A bearing assembly protected by seals to retain lubrication and reduce contamination.

A sealed ball bearing contains rolling balls within a bearing assembly protected by seals. The product data specifies sealed ball bearings in the wheels used by a sliding-door hanger system.

Buying Considerations

Confirm the bearing and wheel construction as a complete hardware system. Proper track alignment and load limits remain important even with sealed bearings.
