Why Your Current Linear Motion Rail Supplier is Costing You
As a purchasing manager or engineer, you’ve likely faced these frustrations with linear motion rails:
💸 Hidden Costs
Paying 40-60% more for branded rails (THK, Hiwin) when identical-spec alternatives exist at factory-direct prices.
⏳ Long Lead Times
Waiting 8-12 weeks for standard rails. YIDI Motion delivers in 15 days with 500+ SKUs in stock.
📏 Precision Compromises
Inconsistent accuracy (±0.05mm tolerance) leading to machine downtime or rejected batches.
🔄 Inflexible MOQs
Forced to order 100+ units when you only need 20. YIDI offers no MOQ for stock items.
🌍 Customs Hassles
Delays due to incorrect HS codes or missing certifications. We handle CE/RoHS compliance for seamless import.

- Fast Delivery: 15-day lead time for standard sizes (HSR15/20/25/30/35/45). 48h express for stock items.
- Customization: OEM/ODM for lengths (100-6000mm), preload classes (C0-C3), and surface coatings (chrome, black oxide).
- Quality Assurance: ISO 9001:2015 certified, 100% inspected before shipment (hardness, roughness, straightness).
- Global Compliance: CE, RoHS, REACH certified. HS Code: 8482.99.00 for smooth customs clearance.
🔍 Round Rail vs. Square Rail: Which Fits Your Application?
Not sure whether to choose round rail (SHS) or square rail (HSR/QR)? Here’s a quick comparison:
| Feature | Round Rail (SHS) | Square Rail (HSR) |
|---|---|---|
| Load Capacity | Moderate (4-way equal load) | High (4-way + moment load resistance) |
| Accuracy | ±0.05mm/m | ±0.03mm/m |
| Speed | Up to 5 m/s | Up to 3 m/s |
| Best For | Lightweight apps (3D printers, laser cutters) | Heavy-duty (CNC, robotics, semiconductor) |
| Cost | ⭐⭐ (Budget-friendly) | ⭐⭐⭐ (Premium) |
💡 Pro Tip: For high-precision CNC machines, opt for square rails (HSR). For cost-sensitive, high-speed applications, round rails (SHS) are ideal.
📊 Technical Specifications
Our linear motion rails are available in the following configurations:
| Model | Width (mm) | Height (mm) | Load Rating (N) | Precision Grade |
|---|---|---|---|---|
| HSR15 | 15 | 23 | 4,800 | C0/C1 |
| HSR20 | 20 | 30 | 8,500 | C0/C1/C2 |
| HSR25 | 25 | 38 | 13,600 | C0/C1/C2 |
| HSR30 | 30 | 45 | 19,600 | C0/C1/C2/C3 |
| HSR35 | 35 | 52 | 26,500 | C0/C1/C2/C3 |

FAQ: Linear Motion Rail Procurement, Simplified
❓ How do I choose between round and square linear rails?
Round rails (SHS) are ideal for lightweight, high-speed applications (e.g., 3D printers, laser cutters) due to their 4-way equal load capacity and lower cost. Square rails (HSR) excel in heavy-duty, high-precision applications (e.g., CNC machines, robotics) thanks to their superior moment load resistance.
❓ What’s the lead time for custom linear rails?
For stock items, we ship within 48 hours. For custom lengths or coatings, the lead time is 15-20 days. Urgent orders? Contact us for expedited options.
❓ Can YIDI Motion match THK or Hiwin specifications?
Yes! Our linear motion rails are dimensionally interchangeable with THK (HSR/QR) and Hiwin (MGW/MGN) series. We use the same GCr15 bearing steel and heat treatment processes to ensure identical performance.
❓ Do you provide CAD models for integration?
Absolutely. We offer free 2D/3D CAD models (STEP, IGES, DXF) for all our linear rail products. Request them via email or download from our online portal.
❓ What’s your MOQ for linear motion rails?
For stock items, there’s no MOQ. For custom orders, the MOQ is 10 units (negotiable for high-volume clients).
❓ How do you ensure quality control?
Every rail undergoes 100% inspection for:
• Hardness (HRC 58-62)
• Straightness (±0.03mm/m)
• Surface roughness (Ra ≤ 0.4μm)
• Dimensional accuracy
We also provide third-party lab test reports upon request.
❓ What payment methods do you accept?
We support:
• T/T (30% deposit, 70% before shipment)
• L/C at sight
• PayPal/Western Union (for orders under $5,000)
• Alibaba Trade Assurance (for added security)
❓ Do you offer samples?
Yes! Order free samples (shipping cost applies) to test our linear motion rails in your application. Contact us with your model number and quantity.
Real User Reviews

"Replaced my worn-out THK rails with YIDI’s HSR30. The smoothness is identical, and I saved $800 per machine. Will buy again!"
Emma R. – ★★★★★
Automation Engineer, UK
"Ordered SHS15 rails for a 3D printer build. Arrived in 10 days, and the tolerance was spot-on. Great value!"
David K. – ★★★★☆
Maintenance Manager, Australia
"The stainless steel option solved our corrosion issues in a humid environment. Only 4 stars because shipping took 21 days (but that’s on the courier)."
