Overview
This 20KG high-torque digital servo is designed for RC steering and robotic joints, featuring 270 rotation, IP65 protection, and an all-metal gear train with metal output shaft. It is positioned for 1/8 and 1/10 scale RC cars and robot arm projects that require strong torque and stable control.
Key Features
- 20KG CM class high-torque digital (non-analog) servo with 270 rotation
- IP65 protection
- High-precision digital design with MCU control
- All-metal internal gears and metal output shaft
- Double ball bearings for smoother operation
- Oxidized metal middle frame for improved heat dissipation
- High-precision potentiometer for improved accuracy/linearity and stable operation
- Coreless motor core (low rotor inductance, fast response, high efficiency, compact size)
- 3-wire lead with Signal / Positive pole / Negative pole

Details
Choose between the standard and upgraded 20kg 270° servo versions by comparing weight, voltage range, current draw, speed, and stall torque.
High-torque digital control with a metal gear train and IP65 protection for RC steering and robotic joints.
Balanced torque and fast response help keep steering and joint motion stable under load.
An oxidized metal middle frame supports heat dissipation, while double ball bearings and metal gears improve durability.
A high-precision potentiometer and coreless motor design support smooth 270° travel and responsive control.
Use the dimensioned drawing to confirm fitment and mounting hole alignment before installation.
Standard 3-wire lead (signal/positive/negative) with a 29 cm cable length simplifies integration into RC and robotics builds.
Common applications include Ackermann-style steering linkages and large-angle joint mechanisms.
Ideal for robot arms and bionic robotics where wider joint rotation helps expand motion range.
A free course document bundle includes tutorials, a quick guide, sample code, and 3D drawings.
Each pack includes the 20kg 270° single-axis servo plus a plastic accessory kit with horns and screws.
