Product overview
Zhuhai SV Tech Co., Ltd.’s AXR 6812 TG is a standard servo for RC steering, control surfaces and mechanisms. Its physical configuration combines an iron-core motor, stainless steel gears and two bearings in a 40 × 20 × 36.3 mm package weighing 49 g. A 300 mm lead provides the electrical connection, while PWM control operates at 333 Hz. Integration requires matching the supply, mounting pattern and arm connection, with the final mounting drawing and interface version established before machining mating parts.
The servo accepts 4.8–8.4 V, with performance figures specified at 4.8, 6 and 7.4 V. At 7.4 V it provides 23 kg·cm stall torque and a 0.095 s/60° no-load speed, alongside a separate 7 kg·cm rated torque. Stall torque cannot serve as a continuous load rating. The 1520 µs reference pulse differs from the 1500 µs position centre, so controller neutral and usable travel require checking for the delivered version. Power provision must accommodate transient current, and movement must avoid sustained contact with mechanical stops.

| Load-sizing limitation | Stall torque is not a continuous load rating; mechanism sizing must account for rated torque and duty cycle. |
| Neutral and travel qualification | The 1520 µs reference pulse differs from the 1500 µs position centre; neutral setting and usable travel require confirmation for the controller and delivered version. |
| Mounting qualification | Drawing and tabulated dimensions may use different datums; mating parts require the final mounting drawing and interface version. |
| Electrical and mechanical integration precautions | Allow for transient current and prevent voltage drop, reversed connections and sustained contact with mechanical stops. |
