A Servo Hub Shaft is one of several integral parts of a ServoBlock. The 0.80″ long shank provides ample room to run a 1/2″ bore bearing around it to isolate radial load from being applied directly to the spline of your servo. The top of the Servo Hub Shaft is 1″ in diameter and possesses the Actobotics 0.770″ hub pattern (8 x 6-32 threaded holes) so that other Actobotics components can easily be attached. The center bore provides easy access to allow you to install the stock servo screw which will hold the Servo Hub Shaft down onto the servo. Servo Hub Shafts are offered with the 24 Tooth (C1)  or 25T spline, which means they’re compatible with most servo brands on the market. Patented.
