Wind Turbine Blade Hubs

Wind Turbine Blade Hubs

Wind Turbine Blade Hubs

Our Wind Turbine Blade Hubs have a 17 mm hub center center mounting hole that fits most older GM/si type alternators.  If your PMA or PMG rotor shaft isn't 17 mm, see our wind turbine hub adapters to make them compatible with our hubs!

 

  • 1/4" bolt holes are 15/16" center to center and are spaced perfectly for our Raptor Generation 4 blades
  • Each wind turbine hub is laser cut for precision
  • Perfectly balanced, will not bend
  • Evenly spaced cooling holes to prevent overheating
  • Made in the USA
