New line of
gearboxes with GHA treatment

Worm and bevel helical gearboxes with aluminum alloy case, equipped with stainless steel nuts, bolts and hollow output shaft. An exceptional feature of these gearboxes is the innovative patented "GHA" treatment applied to the external and internal surfaces of the gearbox housing, to which it confers extraordinary chemical-physical properties.

Innovative gearboxes with GHA treatment

What does "GHA" mean?

The "G.H.A." (Golden Hard Anodizing) treatment is the latest and most innovative technology applicable to aluminum-based alloys surfaces. This is an anodic oxidation process enriched with silver ions which gives the treated surface exceptional antibacterial, anti-corrosion, anti-wear and thermal conductivity properties.
The anodic oxidation generates a protective layer of ceramic type, very hard, refractory to heat and unremovable.

Moreover, by means of a patented process, the typical porosities of the anodic oxide crystals are galvanically sealed with silver ions.

The high hardness of the anodic oxide and the uniform distribution of the silver ions guarantee chemical-physical properties of extreme interest for applications in the food, pharmaceutical and marine fields. The GHA gearbox line is an exclusive Tramec patent.

  • High hardness of the GHA-treated surface (HV 500-600)
  • High resistance to abrasive wear
  • Excellent thermal dissipation
  • High efficiency
  • Ability to withstand high voltages, thanks to the non-magnetic characteristics.
  • Stainless steel nuts and bolts

Advantages

GHA gearboxes VS stainless steel gearboxes / with other treatments

Thanks to the special properties conferred by the patented treatment to which they are subjected, gearboxes  and motors of the GHA series are an excellent alternative to those exclusively made in stainless steel or treated with other processes (i.e. nickel plating or special paintings).

  • External surface actively antibacterial vs. inert surfaces, which do not prevent bacterial proliferation
  • 1/3 lighter than stainless steel
  • Over 13 times higher thermal conductivity (204 W / m ° C) compared to stainless steel (15 W / m ° C)
  • Cheaper than the corresponding stainless steel version
  • Nickel free
  • Non-magnetic motors, capable of withstanding high voltages
  • Safe and aseptic

Respect for the environment

They are Eco-Friendly: made with non-polluting and completely recyclable components;

They can be cleaned with ECO-sustainable and non-polluting products with a potentially neutral pH; cleaning with highly polluting products such as sodium hydroxide (caustic soda) is not recommended;

For the production of a GHA reducer much less energy is required than for the corresponding stainless steel product;
