Always with a high level of efficiency, our helical gearboxs offer an optimum ratio between torque output and installation space. This means: a helical gear unit almost always fits your application.
R Series Helical gearboxs are the "hidden classics" in our gear unit portfolio: 6 single-stage and 15 two- and three-stage frame sizes cover a torque range from 50 to 18 000 Nm. This gear unit series is also far ahead in terms of gear unit ratios: from i = 1.30 to i = 289.74, in double gearboxs even i = 27 001. Torque ratings and gear unit ratios this finely stepped are hard to find in the market.
