Crankshafts generate the rotational force in combustion engines. Our crankshafts are used to propel ships, for example, and a wide range of other machinery and equipment. With our more than 60 years of machining experience, we are noted for our high level of expertise in the production of heavy-duty crankshafts for ships and for use in machinery such as high-power stationary engines, pumps and compressors.     

Production process

We cover the complete value chain in crank and camshaft production - from the melting and forging processes up to and including the ready-to-install product. Optimized steel compositions, perfectly harmonised processes and high-performance production machinery and equipment guarantee the top quality and excellent dimensional accuracy of our products.    


"Renowned experts in crankshaft production, we are the first address for top-performing crankshafts manufactured exactly to our customers' specifications and demands. In addition to serial production we also produce one-off crankshafts and prototypes. Whatever the specifications and number of items ordered: We always guarantee top quality, maximum precision, excellent customer support and on-time delivery. 
Additional services: reconditioning and repair, after-sales support, including damage and wear analyses of crankshafts."
