Gear Couplings

MAINA has been manufacturing gear couplings of all types and dimensions for over sixty years.

Our range includes:

  • standard GO-A couplings, with an outer flange diameter of up to 500 mm;
  • large GO-B and GO-B HT couplings, with an outer flange diameter of up to 2000 mm;
  • G20, G35 and G60 couplings for special applications, suitable for severe misalignments, up to 6 degrees;
  • GTS gear couplings for hoist barrels;
  • HS high speed gear couplings, with accurate precision-ground gear teeth, suitable for speeds of up to 36500 rpm.

The finest quality raw materials and the highest accuracy of the machining, thanks to the latest toothing machines, enable MAINA to achieve maximum load capacity in minimum space and the longest lifetime with minimum maintenance.
