7mm Wide Linear Rails
Miniaturization has revolutionized the field of precision motion systems. One standout innovation is the 7mm wide linear rail, designed to offer compact, smooth, and highly accurate linear motion in tight-space applications.
YH Linear Motion Systems (https://yhlinear.com/) has taken the concept of miniature linear guides to the next level with its 7mm wide linear rails, delivering cutting-edge performance for robotics, medical devices, 3D printing, and automation industries.
What Are 7mm Wide Linear Rails?
A 7mm wide linear rail is a miniature version of a standard linear guide system, engineered for applications where space is limited but precision cannot be compromised. These rails are narrow (just 7mm across) yet provide exceptional load-bearing capacity and motion smoothness.
Their compactness makes them perfect for micro-automation, optical systems, small CNC machines, and portable inspection tools. Despite their size, they maintain industrial-level accuracy comparable to larger rails.
Why Size Matters in Linear Rails
Smaller rails like the 7mm wide linear rail bring unique advantages:
Space Efficiency: Ideal for compact designs without sacrificing rigidity.
Reduced Weight: Lighter systems contribute to higher efficiency and reduced inertia.
Enhanced Speed: Lower mass allows for faster acceleration and deceleration.
Miniaturized Automation: Enables development of smaller, smarter robotic and inspection systems.
In industries where “every millimeter counts,” these compact rails are the foundation of innovation.
Design Features of 7mm Wide Linear Rails
| Feature | Description |

Comparing 7mm Rails to Standard Rails
| Feature | 7mm Linear Rail | Standard Linear Rail |
|---|---|---|
| Width | 7mm | 12–20mm+ |
| Load Capacity | Moderate | High |
| Weight | Very Light | Heavier |
| Application | Compact systems | Large machinery |
| Noise Level | Low | Moderate |
| Speed | High | Variable |
| Precision | Very High | High |
While smaller in size, 7mm rails deliver impressive rigidity and stability for their scale.
Load and Speed Characteristics
Dynamic Load Rating: Up to 700–1,000 N (depending on model)
Static Load Rating: Up to 1,500 N
Speed Limit: Up to 2 m/s continuous motion
Operating Temperature: -20°C to +80°C
Accuracy Class: C, H, or P precision available
These specifications make them suitable for both light-duty automation and high-speed motion systems.
Material and Surface Treatments
YH Linear offers 7mm rails in several material and coating options:
Stainless Steel (SUS440C): Corrosion-resistant for cleanroom environments.
Chrome-Plated Alloy Steel: Superior hardness and wear resistance.
Nickel Coating: Added corrosion protection for humid environments.
DLC and Teflon Coatings: Low friction and self-lubricating performance.
Each rail undergoes grinding, hardening, and inspection to ensure precision and durability.
Installation Guidelines
Clean the mounting surface thoroughly.
Align the rail using precision alignment tools.
Secure bolts with even torque distribution.
Slide the carriage to check for uniform smoothness.
Apply lubrication via provided ports.
Run an initial test cycle at low speed.
Proper installation directly affects accuracy and rail lifespan.
Maintenance and Longevity
To maintain peak performance:
Lubricate every 200–500 hours of operation.
Use cleanroom-grade grease for delicate systems.
Inspect raceways for debris or scoring.
Replace seals or wipers periodically.
Store rails horizontally to prevent deformation.
With regular maintenance, YH Linear’s 7mm rails can last over 30,000 km of operational travel.
