1309 Series Sonic Hub (8mm REX Bore)


This hub has an 8mm REX bore to match our 8mm REX shafting.  The hex profile creates a positive drive that can handle heavy torque loads without concern of rounding out.  The Sonic style hub is perfectly balanced for high-speed applications.  The unique design conforms tightly around a shaft when tightened, without distorting the threaded holes on the goBILDA 16mm pattern.  The outer profile is 32mm so that it can be run in a bearing to isolate radial loads, or even clamped around!
