Two custom-designed machines enable us to spin cast bearings up to
48 inches in diameter. These machines employ bottom draw pouring furnaces
and inert gas pressurization of the cavity being cast. This guarantees
an oxidation-free environment for the molten metal.
This is how a coreless casting looks just after being produced on
our machine. With the centrifugal casting process, all impurities
migrate to the center or waste area with all virgin babbitt securely
suspended on the walls of the shell, which yields a completely void-free
casting and superior grain structure for extended wear and reliability.
After the bearings are cast, they are proof-machined and ultrasonically
inspected for bond integrity.
