Federal-Mogul Göteborg AB is one of the world’s leading suppliers of Daros® piston rings for the global marine and ship industry.
Piston ring packs for advanced, large bore engines
Federal-Mogul Göteborg AB designs and manufactures piston rings, and offers its expertise for materials, geometry, tribology and coatings.
The company develops optimised ring packs for advanced, large bore engines, including ring solutions of up to 980mm.
Piston rings are available for new engines, where designers have changed combustion chamber conditions to gain improved engine performance, and for existing vessels, where ship owners require extra or specific features.
World-class capabilities for industrial piston ring development
The acquisition of the former Daros Piston Rings AB in Göteborg in 2010 further expanded Federal-Mogul’s leading position in the industrial piston ring sector.
The combination of complementary technologies provides major engine manufacturers with a single, consistent sales and service channel for different product types.
Daros is now used as a brand name for all two-stroke rings, whereas Goetze is the brand for all four-stroke rings. Product and process development is driven through a global network of locations to support the industrial engine customer base.
World-class capabilities for industrial piston ring development are offered by an experienced team in Friedberg and Burscheid / Germany and Gothenburg / Sweden using extensive global test and development facilities.
Piston ring technology with sealing properties
Federal-Mogul develops piston ring technology with durable and highly efficient dynamic sealing properties, which helps clients achieve better fuel efficiency, lower emissions and longer overhaul intervals.
Material properties, coating performance and ring design all contribute to a dynamic sealing system, which delivers maximum service life and minimum maintenance.
The company uses its extensive experience in large bore engine applications to create reliable engines with a typical lifespan of 20-30 years.
