HS-85MG
13mm, 3-Pole, Standard Voltage, Metal Gear Actuator (6V)
The HS-85MG is a compact, high-reliability servo actuator built for demanding commercial and industrial applications. Its 3-pole ferrite motor with metal gears delivers consistent 3.0–3.5 kgf·cm (41.7–48.6 oz·in) of torque at standard 4.8–6V operating voltages, while weighing just 21.9 grams in a 29×13×30mm package.
Key Features:
- Metal gear train with 4-gear metal construction for durability under load
- Top ball bearing output shaft reduces friction and extends service life
- 24-segment spline (Ø5.76mm) for secure horn fitment
- Analog circuit with standard PWM command protocol — compatible with most standard RC and industrial controllers
- Standard rotation with conventional potentiometer feedback
Ideal Applications: The HS-85MG is well suited for UAV control surfaces, robotics joints, and light industrial automation where space and weight are constrained but reliable torque output is critical.
