SGS Series Helical Worm Gearmotors

Superior Gearbox’s SGS Series right angle gearmotors offer helical-worm gearing that combines durability with exceptional performance in a compact design. Its helical input stage provides greater efficiency than a single stage worm unit. An additional helical gear unit added to the input enables very large ratios.

Product Range

  • Power ratings from 0.05 to 46 HP
  • Ratios from 3.97 to 33,818
  • Output torques to 35,400 lb-in

Reducer

  • Efficiency up to 94%, depending on ratio
  • Worm shaft and helical gears manufactured from certified steel, heat treated to a case hardness of 58-62 Rockwell C
  • Gears are milled, hardened and ground to assure minimum noise, minimum heat, and maximum efficiency
  • Torque rating based upon mechanical capacity under continuous duty operation
  • Gearcases made of high strength gray cast iron
  • Anti-friction bearings for optimum load capacity and long life
  • Captured keys on input and output shafts
  • O-ring on flange to prevent oil leakage when mounted on a surface that is not totally flat
  • High cross-section modulus design, rugged monobloc design for maximum rigidity
  • Center tapped holes on output shafts to aid the installation of shaft components
  • Metric or Inch dimension output shaft
  • Removable inspection cover

Motor

  • Inverter duty
  • Connection terminals
  • Low rotor inertia for high cycling and tight control
  • EISA (IE3) “Premium” available
  • 50Hz, 60Hz, or 50/60Hz global motor for shipment into Europe

Mounting

  • Torque arm for shaft mounting
  • B14 or B5 flange with centering tenon
  • Foot mounting
  • Can be ordered for any mounting orientation

Optional Features

  • C-Face or IEC motor adapter
