SMS group has banked almost 100 years of experience in ring and wheel rolling. This dates back to Keller & Banning Maschinenfabrik und Eisengießerei (machine works and iron foundry) and Wagner Maschinenfabrik. Today, our ring and wheel-rolling activities stand for innovative technology, precision, and top quality. Almost 600 ring-rolling machines, over 100 complete plants and facilities, as well as satisfied customers all over the world conclusively prove our leading position. So you can rest assured: we know the industry inside out and meet your expectations.

Ring blank presses
Top quality starts with the blankCrucial to your products are the ring blanks. The better the starting product matches the final ring shape, the more cost-efficient your downstream processes are. This in turn means higher productivity. That's how you benefit from our reliable, future-proof ring blank presses with press forces of up to 100 MN.
Ultimate solutions - custom-made for you
Pressing forged ring blanks involves upsetting, pre-piercing, and piercing. There is also an extra step for profile blanks in the form of profiling. Sleeve-type rings are forged in a pot die. So, whatever the application and power range you want - we supply the right ring blank press for you.








Radial and radial-axial ring rolling machines
Wide range of profilsOur ring rolling machines produce rings by enlarging the diameter of ring blanks. The process works like this: first, the blanks are heated to forging temperature. Then, our radial ring rolling machines reduce their wall thickness using a main roll and a mandrel. Alternatively, radial-axial ring rolling involves two axial rolls which simultaneously decrease the height of the blanks.
Ring expanders
Lower-cost ring productionHere is another highlight from SMS group - our ring expanders which are perfect for ring rolling machines. The core components are a hydraulically movable expanding cone and expanding jaws. This is how you achieve excellent plastic deformation of rings. It's an extra advantage that the control system automatically accounts for the spring-back and compensates it during the next expanding stroke.

RAW ecompact®
Innovative drive concept for ring productionWhat's best about our new electrohydraulic drive solution is that it saves you serious money. That's because it consumes between 25 and 50 percent less energy than conventional ring rolling machines. Instead of a large central hydraulic system, several small, self-contained electrohydraulic drives provide the necessary energy - wherever and whenever you need it.
Your benefits at a glance
- Low investment costs
- Lower operating costs
- Lower noise emissions
- Compact dimensions
- Automatic control and software included
- Short delivery times and fast commissioning
