Flange-Mount Ball Bearing Units
Cast iron flange units are designed to support shafts through walls, bulkheads and other flat surfaces. The medium duty flange housings accommodate a larger bearing for a given shaft size, resulting in a greater load carrying capacity . Both series are supplied with a grease fitting for relubrication and provide for initial bearing alignment. 
Both the cast iron and medium duty flange units are available in four bolt (F4B) and two bolt (F2B) configurations.
