A Hiwin Single-Axis Robot is a compact, self-contained linear motion module that integrates:
A linear guide
A ball screw or belt drive
A servo motor or stepper motor
It is designed for precise linear motion along a single axis and is widely used in automation, pick-and-place systems, and manufacturing lines.
Hiwin’s single-axis robots are known for:
High precision
High stiffness
Compact design
Easy integration
🧩 Components of a Hiwin Single-Axis Robot
Component Description
Linear Guide Provides smooth and rigid guidance (typically from Hiwin’s LM guides)
Drive Mechanism Either ball screw (for precision) or belt (for speed and long travel)
Motor Servo or stepper motor integrated or user-configurable
Base Frame Aluminum or steel extrusion for stability
Carriage/Slider Moves along the axis, carries payload or tool
Limit Sensors Home, end-limit, and optional origin sensors for positioning
Cover Dust-proof or sealed options available
