About Zahnradfabrik Liesen
Zahnradfabrik S. Liesen is a gear manufacturer based in Unna, North Rhine-Westphalia, producing transmission components according to customer requirements. The specialty is spur gears, pinion shafts and gear couplings, manufactured from engineering drawings, enquiry sketches or sample/prototype. Production covers single parts as well as small and medium batch sizes. Geometry quality control is performed separately from the grinding machine on a fully automatic CNC-controlled gear measuring machine that inspects workpieces up to 1,000 mm in diameter and up to 1,500 kg and documents the quality. The company offers full service including consultation, planning, manufacturing and shipping readiness. Since 1992, more than 100,000 gears have been manufactured. Production takes place in Unna on Hammer Straße, where the administration is also located.
