SKF®
FY 1.1/4 AFM

Four-bolt cast iron flange units are designed to support shafts through walls, bulkheads and other flat surfaces. The housing mounts flush to the surface and the load is carried by the four mounting bolts. F4BM medium duty 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.
