HISTORY

Today’s Koellmann Gear Division of the Thielenhaus Group dates back to the Köllmann GmbH gear factory, which was founded in Leipzig in 1904. Originally producing precision gear wheels and specialising in bevel gears, in 1907, Köllmann became the first special factory to produce rear axles and change speed gears for the automotive industry. Köllmann also produced the gear cutting tools required for this work. In addition to the production of gears and tools in Leipzig, long milling machines were built in Langenberg. The company then moved its headquarters there after the end of the Second World War, before moving to Düsseldorf-Heerdt in 1951.
