Seamless Tube and Hollow Bar

Ovako’s tubes and hollow bars are used when there are stringent demands on the material, such as within the rolling bearing, automotive, hydraulic and manufacturing industries. As a service to our customers, we have a standard tube program offering smaller order quantities and a shorter lead time than we normally require for a production batch. Ovako has two such standard programs. The bearing steel program covers roughly 350 tube sizes from OD 50.6 to 243.5 mm, and the Ovako 280 hollow bar program that covers microalloyed steel hollow bars in grade Ovako 280 based on the standard EN 10294. Within the Ovako 280 hollow bar program, we keep roughly 250 dimensions in stock from OD 30 to 242.7 mm. Both the bearing steel tubes and the Ovako 280 hollow bar program are based on tight machining allowances. For each item we can provide a guaranteed finished turned size for either inner or outer chucking. Both have the tubes stocked at our mill as well as at some of our sales companies and appointed distributors. In addition to the bearing steel program and the Ovako 280 hollow bar program, we supply tubes in all Ovako standard steel grades. 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.
