Your benefits

  • Reduce noise

    as the helical-worm gearmotor minimizes noise pollution in the area surrounding your system thanks to its running smoothness.

  • Increase efficiency

    because the gearmotor offers a high degree of efficiency thanks to its combination with a helical gear stage in the

Helical-worm gear units

  • Helical-worm combinations with significantly better efficiency than single helical-worm gear units
  • Very low-noise operation
  • Available variants:
    • Foot- or flange-mounted
    • B5 or B14 flange-mounted
    • Solid or hollow shaft
    • Hollow shaft with keyed connection, shrink disk, splined hollow shaft, or TorqLOC®
