1. Linear Guide: Responsible for Straight, Stable Movement
A linear guide acts as the track and support for machinery, bearing loads and constraining motion direction to ensure moving parts stay aligned, steady and undistorted.
It only provides guidance and load-bearing without thrust, but determines rigidity, straightness and service life.
It is widely used in robotic arms, dispensing machines, cutting machines, 3D printers, CNC machines and more - any equipment requiring reciprocating linear motion relies on HGR Linear Guide And SFU Ball Screw for stable performance.
2. Ball Screw: Responsible for Driving & Precise Positioning
A ball screw serves as the power actuator, converting motor rotation into linear thrust.
It handles transmission and positioning, delivering force and controlled displacement for high-precision feeding.
Simple rule:
①Linear guide = controls direction & bears load
②Ball screw = provides thrust & ensures positioning
3. Linear Guide + Ball Screw: The Perfect Precision Motion Pair
Working together, they form a complete precision motion system:
①Ball screw pulls and pushes the load
②Linear guide keeps it on track without deviation or shaking
Like a locomotive and railway - no ball screw means insufficient power; no linear guide means unstable direction.
The accuracy, speed and stability of laser machines, soldering machines, engraving machines and inspection equipment are mostly determined by this combination.
4. Quick Selection Tips
①For linear guides: Higher load requires wider guides and more blocks
②For ball screws: Longer travel and higher speed need thicker screws
③Golden match: Guide width ≈ screw diameter for optimal rigidity
These small components are the motion soul of equipment. Lishui City Hengli Automation Technology Co.,LTD manufactures every HGR Linear Guide And SFU Ball Screw to strict standards, delivering stable, precise and reliable motion control solutions.
5. Integrated Solution: Linear Stage Modules
Lishui City Hengli Automation Technology Co.,LTD also provides pre-assembled linear stages for plug‑and‑play convenience, no on-site assembly or alignment needed.
Ball Screw Linear Modules
Driven by a servo motor rotating the ball screw, the nut drives the stage linearly.
Advantages: high precision, strong rigidity, smooth transmission.
Suitable for high-precision positioning and heavy‑thrust applications: dispensing machines, assembly equipment, inspection platforms.
Linear Stage Selection Guide
①Short travel, high precision, heavy load: choose 5mm or 10mm lead
②Long travel, high speed, light load: choose 16mm or 20mm lead
