Deep Groove Ball Bearing Description
Deep groove ball bearings are one of the most common style of ball bearings which support axial forces in both directions as well as radial forces. The bearing has a single row of balls retained in a cage and is sealed for life with an NBR seal on both sides of the bearing, the bearing is pre-greased which means you do not need to lubricate the bearing.
