Kumera SF-, SG-, E-Series - High External Loads Gearbox Range

The SF-, SG-, E-gearbox series are specifically designed for vertical shaft applications with high external loads. These ranges include in total 30 gear unit sizes, which are optimally divided to meet required torque ranges, ratios and shaft end load requirements.

The output shaft, bearings and housing are designed to withstand high external loads. The E-series gearbox can be equipped with a flanged output shaft to achieve the highest possible load capacity and bending stiffness.

The SF- and SG-series are equipped with lip seals. E-series gearboxes are equipped with drywell seals on the output shaft and labyrinth seal on the input shaft to ensure maximum usability.

The gearbox can be connected to a structure with a standard cast iron connection foot or an easily customizable plate foot to maximize versatility in final assembly.

Technical data:

  • Nominal torque rating   0,5 - 850 kNm
  • Nominal power rating up to 6000kW
  • 42 catalogue gear ratios from 5,6:1 to 630:1  (special ratios on request)
  • 30 gearbox sizes; shaft center distances from 80 mm to 800 mm
  • Weight from 32 kg to 20 000 kg
