SCHLEIFRING (Schleifring GmbH, also known as Schleifring und Apparatebau) is a German technology company headquartered in Fürstenfeldbruck, Bavaria, with a second German production site in Kaufbeuren. It develops and manufactures electrical slip rings and contactless rotary transmission systems (Drehübertrager) that transfer electrical power, signals, data and media between stationary and rotating components. The company describes itself as the global technology and market leader for slip rings and rotary transmitters, serving more than 3,000 customers worldwide with a team of over 700 employees. According to its own materials, it has completed more than 6,000 custom developments, holds over 260 patents, and operates from five international locations. SCHLEIFRING was founded in Fürstenfeldbruck in 1974. In 1980, Wegmann & Co. Beteiligungsgesellschaft mbH became the majority shareholder with 90% of the company. A second German production facility opened in Kaufbeuren in 1997, focused on slip rings for medical and safety technology. In 2000, Schleifring North America, LLC was established in Elgin, Illinois. The company introduced its first complete gantry system for CT scanners in 2003 and received the Bavarian Mechatronics Innovation Prize in 2004. In 2006, Siemens Medical Systems named it "Supplier of the Year" in the quality category, selected from 1,422 suppliers. In 2010, the Fürstenfeldbruck plant was expanded and Schleifring Transmission Technology (Tianjin) Co., Ltd. was founded in China for sales and service of wind turbine slip rings. In 2020, Schleifring GmbH acquired 100% of Electro-Miniatures Corp. (EMC) in Moonachie, New Jersey, USA, a developer and producer of slip rings for military applications and satellites. In 2026, the company founded Schleifring Cable Solutions, s.r.o. (SCS) in Trenčín, Slovakia, to manufacture cable assemblies for the defense sector. SCHLEIFRING's products are used in wind turbines for hydraulic or electrical pitch adjustment, medical technology (CT scanners with inner diameters up to two meters), radar systems, the defense industry (e.g., armored vehicles and tank turrets such as the Leopard 1, Leopard 2, Puma infantry fighting vehicle and Gepard anti-aircraft gun tank), safety technology and baggage scanner slip rings, aerospace (vacuum, extreme temperature fluctuations, ionizing radiation), remotely operated vehicles (sonar, underwater cameras, oil extraction), and industrial applications including automotive, pharmaceutical, food and printing industries. Transmission technologies include contacting power/signal/data transfer via gold spring wire, metal graphite and silver band contacts; contactless inductive power transfer and capacitive data transfer; optical signal transmission via fiber optics; high-frequency transmission up to about 250 MHz; contactless data transmission up to 10 Gbit/s; and media rotary unions or hybrid systems for liquids and gases. The company is the parent company of the Schleifring Group and operates as the top entity of the Schleifring business segment within Wegmann Holding. Its subsidiaries include Schleifring North America, LLC and Electro-Miniatures Corp. in the USA, Schleifring Transmission Technology (Tianjin) Co., Ltd. in China, and Schleifring Cable Solutions, s.r.o. in Slovakia.
