Product Description

DHS helical worm gearbox stainless gearboxes

Our complete range of helical-worm gear stainless steel SS316 units are helical/helical-worm combinations, providing higher efficiency than common helical-worm gear units. The footprint and shaft sizes are similar to common used standards and sizes S37, S47, S57, S67 in the market.

The DHS series is a direct replacement to the SEW S series gearboxes (S37, S47, S57, S67). This means that it only takes 4 bolts to be loosened and 4 bolts to be tightened in order to go from a common cast iron gearbox to stainless steel hygienic design gearbox. In this way the high standards of hygiene requirements in the food industry are met.

  • The housings are produced from first class electro polished SS316 stainless steel.
  • Hygienic, round and the smooth design ideal for the food industry.
  • All hollow shafts are produced in Duplex Stainless Steel 2205
  • Filled with food grade gear lubricant, NSF-H1 certified
  • High quality HNBR seals, for performance at wet/harsh environments and broad chemical resistance.
  • Laser engraved technical characteristics instead of tagplate to avoid dirt traps.
  • Standard hollow shafts 20, 25, 30, 35, 40 & 45 mm (other metric or inch sizes upon request)
  • IEC motor adaption or with integrated motor (SEW type)

DHS features are:

  • Standard ratio’s 22.5 : 1 to 217.41: 1
  • Standard hollow shafts 20, 25, 30, 35, 40 & 45 mm (other metric or inch sizes upon request)
  • Sizes 38, 48, 58, 68
  • Direct replacement to the SEW S series cast iron gearboxes
  • Output flanges, torque arms, protective caps are optional
