Your benefits

  • Make use of a diversity of applications
    to implement particularly economical applications right from the start. Use combinations from the gearmotor modular concept.
  • Expand energy efficiency
    as our helical gearmotors meet the requirements of efficiency classes IE1 to IE4 meaning that you can use them anywhere in the world.
  • Save time and cut costs
    even in the selection and project planning thanks to the individually configurable, compact helical gearmotors.

Helical gear units

RX series (single-stage)

  • Highly efficient helical gear units in 6 sizes
  • High output speed, up to 830 Nm
  • Gear unit ratios up to i = 8.65
  • Available in foot or flange-mounted design

R series (multi-stage)

  • Optimum ratio between performance and space requirements thanks to 15 sizes
  • Finely stepped gear unit ratios up to i = 289.74; or i = 27,001 for double gear units
  • Available in foot or flange-mounted design
  • Also available with reduced backlash
