Servo Attachments
These various attachments provide a way to utilize the torque created by your servo.
Arms
Servo arms are great for driving linkages and also pair well with beams.
Gears
Transfer the torque of your servo into a gear train with these MOD 0.8 servo gears.
Hubs
Servo hubs have the goBILDA® pattern for easy mounting of other pattern-based components.
Shafts
Servo shafts pair well with bearings to isolate radial loads. Just like regular shafts, servo shafts allow for the attachment of motion components via hubs, though in some cases—such as with the positive-drive 8mm REX™ profile—you can attach gears, sprockets, and pulleys directly to the shaft. Round profile servo shafts are particularly convenient for allowing attached components to be clocked in an unlimited number of ways.
Couplers
Servo couplers adapt the servo spline to drive another shape, such as an 8mm REX™ shaft, in order to transfer the torque created by the servo into other areas of your build.
