As a producer of rolled and forged rings for almost a century, Ovako has a proven track record in this product niche. We strictly control the whole production chain, from melt to the rolling of the rings. For example, to ensure the superior quality of our rings, we carefully manage the levels of oxygen content in the steel to ensure the production of a cleaner steel. Few ring producers can match our commitment to consistent quality from delivery to delivery.
As a result of our quality control, manufacturers can simplify their production processes and reduce their costs because the rings are not only predictably consistent from batch to batch, but also easy to process further. Ovako produces profiled rings with very small allowances and tight tolerances close to the final shape of the end product. In addition, our machined rings enable customers to concentrate resources on finishing and/or assembly. Furthermore, Ovako can offer shot blasted rings of diameters up to 4,000 mm and weights up to 5,000 kg.
Reducing global CO2 emissions demands smarter product solutions and requires rethinking on many levels: more performance benefits per kilogram of product, less raw materials, and substituting fossil fuel energy sources with primarily fossil-free electricity.

Rings can also be heat treated before delivery in a variety of executions such as
- Normalised
- Soft annealed
- Stress relieved
- Isothermally annealed
- Quenched and tempered
Advantages of Ovako's rolled and forged rings
- Consistent quality from batch to batch
- The ability to produce profiled rings close to the final shape of the customer's end product results in more efficient production and cost savings
- Machined rings with close tolerances and an even quality level speeds up production and cuts costs by enabling customers to focus on finishing and/or assembly
Rings to meet the industry's needs
The bulk of our production is consumed by the rolling bearing industry, but a substantial share is also delivered to customers in other industrial segments, such as the heavy vehicle, automotive and machine tool manufacturing industries. The dimensional range is Ø 170 to 4,000 mm and the weight range is 7 to 5,000 kg. Forged rings are also supplied up to 3,400 kg.
Rings with lower widths than stated in the ring mill technical data can often be rolled in multiples and parted. Ovako has a capable machine park for this purpose and expanded its parting capacity with additional state-of-theart parting technology and a packaging robot.
We made it! But we are still not satisfied
What a journey! It took years of hard work to make our steelmaking operations more sustainable. In 2022, we went carbon neutral in all operations. But we´re still not satisfied - our journey towards steel production without CO2 emissions continues.
