About Miba
Miba Aktiengesellschaft, headquartered in Laakirchen, Austria, develops and produces function-critical components along the entire energy value chain. The product portfolio includes hydrodynamic plain bearings (radial, axial and pad bearings up to the Segmented Journal Bearing for wind turbine main bearings), sintered parts such as sintered gear, steering and gear components, friction linings for clutches and brakes, coating solutions, and power electronics components such as resistors, bypass switches and cooling systems. The manufacturing processes range from laser welding of bearing materials onto steel substrates (42CrMo4 with CuSn12Ni2), explosion, cold and hot roll cladding, and electromagnetic pulse technology (EMPT) to special machinery construction including laser-controlled CNC machining of very large components with diameters up to 20 meters. Customers come from automotive, commercial vehicles, rail, aviation and shipping, wind power, power plant and plant engineering as well as oil and gas. With around 7,400 employees at approximately 30 locations in Europe, North and South America and Asia, the group achieved revenue of 1.202 billion EUR in the 2025/26 fiscal year. Reference customers include Bosch, Siemens, GE, Daimler, ZF, Schaeffler, Rolls-Royce, Pratt & Whitney and Volkswagen.
