Precise power/stroke motion sequences thanks to spindle & bevel gear drives

Screw Jacks "Gold" – For Extreme Environmental and Operational Conditions 
The shiny casing, mounting flange and cover indicate the highest degree of corrosion resistance. In simple terms, the conventional aluminum components as well as the external parts have been replaced by components made of the aluminum bronze material CuAl10Fe5Ni5. All the spindles and shafts as well as the internal elements are manufactured from stainless steel or synthetic material (seals). 

Significant Advantages

• High corrosion stability combined with a high degree of wearing resistance and cavitation protection through CuAl10Fe5Ni5
• Resistance against mechanical damages due to an oxide protection film (basically Al203) that immediately forms on the material surface
• Excellent performance in applications with gases, fluids and solid materials

• features high scaling resistance (up to 800°)
• has a lower degree of corrosion resistance to strongly acidic media with high oxidation potential (such as nitric acid) as well as alkaline materials, because these will dissolve the oxide coating and prevent its formation.
• has a lower tendency to selective corrosion (dealumination)
