Product overview
The Zhuhai SV Tech Co., Ltd. AXR 8822 SSG-D is a standard servo for model steering, control-surface movement and mechanical actuation. Its configuration combines a coreless motor, stainless steel gears and two bearings in a 35.5 × 15 × 29.9 mm body weighing 46 g. A 300 mm cable provides connection reach for installation. Integration requires matching the power supply, PWM signal, mounting holes and servo-arm connection, with the final mounting drawing and interface version established before fabricating installation hardware.
The servo accepts 4.8–8.4 V and uses PWM control at 333 Hz. At 8.4 V, it delivers 22 kg·cm stall torque and a no-load speed of 0.101 s/60°, while rated torque is 10 kg·cm. Stall torque is unsuitable as a continuous-load rating, so load selection also depends on duty cycle. The 1520 µs reference pulse differs from the 1500 µs position midpoint; neutral and usable travel depend on the controller and delivered version. Initial setup requires removed or limited load, and the supply needs headroom for transient current.

| Neutral position and travel qualification | The reference pulse is 1520 µs, while the position midpoint is 1500 µs; neutral position and usable travel require confirmation for the controller and delivered version.Controller and delivered version. |
| Stall torque limitation | Stall torque cannot be treated as a continuous load rating; continuous-load selection must also consider rated torque and duty cycle.Continuous-load selection. |
| Voltage range qualification | The operating voltage range defines permitted supply voltage.Operation within the permitted supply range. |
| Mounting dimensions qualification | Drawing and specification dimensions may use different reference points; the final mounting drawing and interface version require confirmation before fabricating mounts.Mount fabrication. |
| Integration and commissioning | Check supply, signal pulse width, mounting holes and servo-arm connection. Establish neutral position, movement direction and mechanical travel before progressively applying the working load.Initial setup with the load removed or limited. |
| Electrical and mechanical constraints | Provide supply headroom for transient current; avoid cable voltage drop, reversed connections and sustained loading against mechanical stops.Supply sizing and mechanical installation. |
