1910 Series Servo Hub Shaft (25 Tooth Spline, 8mm Shaft Diameter, 16mm Length)

Though most servos support their splined output shafts with internal bearings, servos’ internal bearings aren’t designed for significant radial loads. This Servo Hub-Shaft comes to the rescue for 25 tooth (H25T) splined servos! It’s designed to be supported by an external 8mm round bore ball bearing.

The output goBILDA® 16mm pattern, offering four of each thru- and threaded holes, allows this Hub-Shaft to drive hub-mounted motion components such as gears, wheels, control arms, and more across the goBILDA® ecosystem of components. The hex counterbores of its thru-holes allow for the secure capture of hex nuts and hex-head screws.

Speaking of goBILDA® compatibility—the hub pattern conveniently remains on-pattern with nearby components when the hub shaft is installed on a goBILDA® 2000 Series Servo. That’s because the Hub-Shaft’s height was chosen specifically with the spline height of 2000 Series Servos in mind!
