diymore 8125MG Digital Servo Motor, 25 kg, 270°, Metal Gearbox

diymore 8125MG Digital Servo Motor – 25 kg, 270°

A high-torque digital servo motor for RC models, robotics, and DIY projects. The 8125MG features an all-metal gearbox, an aluminum center section, a 270° control range, and an operating voltage of 4.8–8.4 V.

High-torque, durable design

According to the manufacturer’s specifications, the holding torque is approximately 23–27 kg·cm depending on the supply voltage, and the operating speed is approximately 0.18–0.14 seconds/60°. The metal gears, dual ball bearings, and CNC-machined aluminum center section make it suitable even for high-load applications.
