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
