Identifying Surplus Mounted Units
Mounted bearing units consist of a bearing insert housed within a cast iron, steel, or thermoplastic casing. When evaluating surplus inventory, it is critical to identify both the housing style—such as pillow block, two-bolt flange, or four-bolt flange—and the specific bearing insert. Part numbers are often cast directly into the housing, while the insert may have its own distinct markings. Clear photos of these identifiers assist in determining the configuration and shaft size.
