Founded in the first half of the 16th century by Masatomo Sumitomo, a medicine and bookshop owner, Sumitomo still adheres to a business philosophy set out 400 years ago.
Integrity, sound management and a warning against the pursuit of easy gains have stood each company in good stead and made them collectively one of the five largest business conglomerates in the world.
Sumitomo still utilise the distinctive ‘igeta’ symbol as their emblem in a mark of respect to Masatomo Sumitomo, who used it on the family shop in the late 16th century. It symbolises a frame placed around a well in old Japan. Sumitomo Drive Technologies' clients appreciate a worldwide back-up for their unique products.
Lorenz Braren invented the Cyclo gearbox and founded Cyclo Getriebebau GmbH in Munich, Germany, in 1931. He rewrote engineering history when he was granted a patent for his invention, which introduced a totally new concept in speed reduction.
The Cyclo is a speed reducer without a high speed pinion or gear teeth; it does not operate in shear but in compression. This means that users of Cyclo speed reducers enjoy a valuable benefit - no catastrophic failure. Following World War II Lorenz Braren continued to perfect the Cyclo gearbox until he died in 1953, at the age of 67.
