The beginnings

Nanni Gears was founded in 1971 by Silvano Nanni, who from the beginning has worked on the design and production of elliptical gears, which have the characteristic of transforming a uniform rotational motion into a rotational motion with speed varying during each revolution.


Elliptical pulleys, like the gears, also allow a variable speed on the output shaft. Splined shafts: 300 mm diameter x max 800 mm length; 50 mm diameter x max 1800 mm length; 8 mm max module.


Nanni Gears supplies several internationally-renowned companies, particularly manufacturers of automated machines for printing, textiles and general automation, which need to vary the speed of a shaft, a feeder, a blade or a welder in the course of a single revolution.


Pulleys for toothed belts of all kinds; chain gears: max 1200 mm diameter; spur gears and helical gears: from 0.5 mm to 8 mm module, max 1200 mm diameter; elliptical gears and pulleys.
