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

Description

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 12 mm ball screw with 4 mm or 5 mm lead options. The rod end features an M121.25 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.

Key Features

• Two installation styles: Direct coupling and 45 foldback

• Precision planetary gearbox: high accuracy and higher torque output

• Precision ball screw: described as imported, with 2 si accuracy (0.02 mm) in the materials

• Rod end thread options: external thread or internal thread

• Multiple drive choices: servo motor or stepper motor configurations with selectable gear ratios
