Product overview
The Zhuhai SV Tech Co., Ltd. AXR 8810 SSG-D is a standard servo for model steering, control-surface movement and mechanical actuation. Its coreless motor drives stainless steel gears, with two bearings specified in the assembly. The servo weighs 46 g and occupies an external envelope of 35.5 × 15 × 32 mm. A 300 mm cable provides connection reach, while installation requires matching the mounting holes and servo-arm connection to the intended mechanism.
The electrical interface combines a 4.8–8.4 V supply range with PWM control at 333 Hz. At 8.4 V, the servo has a 10 kg·cm stall torque, a 0.062 s/60° no-load speed and a separate rated torque of 5 kg·cm. Performance figures are also specified at 5, 6 and 7.4 V. Continuous-load selection must account for rated torque and duty cycle, while the power supply needs headroom for transient current and cable voltage drop.
Control integration requires attention to the distinction between the 1520 µs reference pulse and the 1500 µs midpoint in the angle mapping. The specified mapping assigns 500, 1500 and 2500 µs to -90°, 0° and 90°, respectively; center and usable travel depend on the controller and delivered version. Initial commissioning should remove or limit load while establishing direction and mechanical travel. Mounting-part fabrication also requires the final installation drawing and interface version because dimensional reference points can differ.
