LORDWORLD

LORDWORLD 25KG 180° Digital Servo Motor PWM

SKU CH-X039-SN2C8

Waterproof digital servo delivers 25 kg·cm torque at 7.4 V with 180° control for robot arms and DIY models

  • High torque for robotic arms with 25 kg-cm at 7.4 V
  • Precise 180° control via high-precision potentiometer and PWM signal
  • IP67 waterproof sealing resists splashes in outdoor or marine builds
  • Metal gears and dual ball bearings give durability with minimal noise
  • Compact anodised aluminium case at 40 × 20 × 40.5 mm aids heat dissipation

Robot steering servo

The LORDWORLD digital servo delivers 25 kg-cm torque at 7.4 V and rotates through 180 degrees. Metal gears and dual ball bearings provide precise positioning for robotic arms, boats, aircraft and general DIY models. An anodised aluminium case aids heat dissipation. IP67 sealing protects against water splashes.

PWM signal and voltage check

Verify that your controller can supply a standard PWM signal and a stable 7.4 V source capable of the servo peak current. The 25T spline horn matches the included metal arm; confirm the mounting pattern suits your frame. This unit is not recommended for RC car steering applications.

Thermals noise and power

The aluminium housing spreads heat during continuous operation keeping temperatures moderate. Dual ball bearings and a high-precision potentiometer keep acoustic output low under load. Current draw scales with torque demand; ensure the power supply can sustain the 7.4 V rail without excessive voltage drop.

Questions about this item

What comes in the box and do I need a separate controller or power supply?

The servo includes a 25T metal horn; a PWM controller and a 7.4V power source must be provided separately.

Should I choose the 25kg 180° version or the 35kg and 20kg alternatives mentioned?

The 25kg 180° model suits robots and robotic arms; the supplier suggests 35kg then 20kg for RC cars.

What does the 25kg.cm torque at 7.4V mean when the servo is installed in a robot arm?

At 7.4V the servo can hold 25kg.cm, giving strong lifting force for joints in robots, arms, boats or planes.
