SSF produces custom seamless rolled rings on rolling mills from approximately Ø 100MM to 1200 MM in outside diameter, and weighing from 1Kg. To 300 Kg. in carbon, alloy, and stainless grades of steel. Certain grades of non-ferrous materials such as copper are also within our rolling capabilities.

In additional to plain rectangular shapes (PRS), all rolling mills are capable of producing ID/OD contour configurations

SSF specializes in the design and manufacture of a wide variety of contoured or profiled seamless rolled rings that reduce input weight and save money on machining costs. Common near-net shapes that we offer are:

• Single cups
• Double-flange OD/ID
• Shaped bearing races
• Train tires
• A variety of custom spherical shapes.
