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.

Types of R Helical Gearbox

  • Single- or multi-stage
  • Foot- or flange-mounted
  • Foot- and flange-mounted
  • Flange-mounted with extended bearing housing

Benefits of R Series

  • Comprehensive offer: Because 6 single-stage and 15 two- and three-stage frame sizes offer finely stepped torque ratings and gear ratios.
  • Easy combination: Because you can easily combine your helical gear unit with an AC motor or a servomotor of your choice from our modular motor system.
