The HS-225BB is a mini servo ideal for applications that call for lightweight, high speed, and lots of torque. The custom designed integrated circuits provide strong standing torque, narrow dead band, and stable operation even at low voltage. This circuitry is matched to a precision gear train and single ball bearing output shaft for ultra-smooth operation. Offered in both resin and metal gears with the standard mounting hardware package, including a full selection of servo horns for any application.
