Special gearboxes in the fourth generation
KACHELMANN GETRIEBE GmbH from Strullendorf near Bamberg is a fourth-generation family business specialising in the design and manufacture of special industrial gearboxes as well as contract manufacturing of drive elements such as gears, shafts, gear racks, bevel gears and Zyklopaloid gearing according to drawing or sample. Materials processed include hardened and tempered steels, case-hardening steels and nitriding steels as well as bronze (including GC-CuSn12Ni, GZ-CuSn12Ni), with in-house heat treatment by hardening and tempering, case hardening and nitriding. The service portfolio includes individual part manufacturing, cross-brand repair and retrofit of third-party products, new manufacture and overhaul of METALLUK couplings, rapid repair, CAD design, reverse engineering of old parts as well as maintenance, condition monitoring and worldwide installation. Customers come from industries such as nuclear facilities, crane systems, chemical industry, plastics and rubber industry, conveying technology, mining and open-cast mining, steel industry, automotive industry, wastewater and sewage treatment plants, municipal vehicles as well as agricultural vehicles and vintage cars. Manufacturing takes place at the site in Germany, installation is carried out worldwide; more than 500,000 gearboxes have been delivered.
