LORDWORLD

LORDWORLD HPS-2518MG 25KG Digital Servo Motor

SKU CH-12FD-8W828

Digital servo with metal gears, dual-ball bearings and IP67 sealing delivers 25 kg·cm torque at 7.4 V across 180° for robots and models

  • Precise 180° control backed by high-precision potentiometer
  • IP67 waterproof rating resists splashes in outdoor robots
  • 25 kg·cm torque at 7.4 V drives heavy loads
  • Metal gears with dual-ball bearings cut noise and wear
  • Compact 40×20×40.5 mm aluminium case dissipates heat efficiently

High-Torque Digital Servo for Robotics

The LORDWORLD HPS-2518MG is a 25KG.CM digital servo built for robotic arms, RC models, and DIY automation. Its metal gear train and dual-ball bearings deliver precise 180° movement under PWM control. An integrated high-precision potentiometer improves linearity and extends operational life for demanding motion tasks.

Upgrade from Standard Plastic-Gear Servos

This unit replaces weaker plastic-gear servos that strip under load or drift over time. The jump is worth it when your project requires 25KG.CM torque at 7.4V, IP67 water resistance, or the thermal stability of an anodized aluminum case. Builders needing only light positional control for small indoor models will not benefit from the added cost and weight.

Check Voltage Supply and Mounting Space

Verify your power source can deliver 7.4V to reach the rated torque; lower voltage reduces output. Confirm the 40mm by 20mm by 40.5mm footprint and 25T spline match your chassis and servo horn requirements. The 68g mass may affect balance on lightweight airframes or multi-servo arms.

Questions about this item

What are the exact dimensions of the anodized aluminum case so I can design the mounting cutout?

The case measures 40 mm wide, 20 mm deep, and 40.5 mm high, with a weight of 68 g.

How do I connect the PWM signal lead to avoid reversing polarity on the first power-up?

Plug the three-wire lead so the orange or white signal wire faces the controller pin marked PWM, red to 7.4 V, and brown or black to ground.

When should I replace the metal gear set or the 25T servo horn after heavy robotic-arm use?

Inspect the metal gears and 25T horn every 20 hours of high-load operation; replace if backlash exceeds 1° or teeth show visible wear.
