RCDrone TDN045 Servo Electric Cylinder Linear Actuator 0-100kg, Ball Screw, Planetary Gear, 45 Series

Overview

The RCDrone TDN045 Servo Electric Cylinder is a 45-series servo linear actuator designed for precise push/pull motion in automation equipment. It supports direct-coupled and 45° foldback mounting styles, uses a precision planetary gearbox for high torque and stable motion, and is built around a Ø12 mm ball screw with 4 mm or 5 mm lead options. The rod end features an M12×1.25 interface, with external or internal thread choices. Based on the provided selection tables, the actuator can be configured for up to 1.00 kN rated output (100 kg) and speeds up to 250 mm/s depending on lead, motor, and gear ratio.
