❓ 1. What's the difference between linear rails and linear guides?

Linear rails (also called guide rails) are the track components, while linear guides refer to the complete system including the rail, carriage, balls, and seals. At YIDI Motion, we manufacture both components to ensure perfect compatibility.

❓ 2. How do I choose the right linear rail for my application?

Consider these factors:

1. Load capacity: Calculate both static and dynamic loads (we provide free load calculations)
2. Precision requirements: Standard (C), High (H), or Precision (P) grades
3. Environment: Corrosive, cleanroom, high-temperature, etc.
4. Speed: Maximum travel speed (our rails support up to 5m/s)
5. Life expectancy: L10 life calculation based on your usage

Need help? Our engineers provide free consultation to select the optimal rail for your application.

❓ 3. Can you provide custom linear rail solutions?

Absolutely. We specialize in:

• Non-standard sizes: Any length from 100mm to 6,000mm
• Special widths: From 15mm to 65mm (or custom)
• Unique hole patterns: Pre-drilled mounting holes to your specifications
• Material customization: Stainless steel, high-temperature alloys, etc.
• Surface treatments: Black oxide, zinc plating, nickel plating, DLC coating

Lead time for custom orders: 6-8 weeks for prototypes, 4-6 weeks for production runs.

❓ 4. What's your minimum order quantity (MOQ)?

Our flexible MOQs set us apart:

• Standard sizes: 10 units minimum
• Custom sizes: 50 units minimum
• Sample orders: 1-2 units available for testing (refundable with bulk order)

Note: We offer volume discounts starting at 100 units.

❓ 5. How do you ensure quality control?

Our 7-step quality control process includes:

1. Incoming inspection: 100% check of raw materials
2. In-process inspection: Real-time monitoring during production
3. Heat treatment verification: Hardness and microstructure analysis
4. Precision grinding check: Surface roughness and dimensional accuracy
5. Assembly inspection: Preload and smoothness testing
6. Final inspection: 100% visual and functional testing
7. Outgoing inspection: Random sampling before shipment

We provide detailed inspection reports with every shipment.

❓ 6. What's your warranty policy?

We offer a 2-year warranty against manufacturing defects, with these terms:

• Coverage: All components (rails, carriages, balls, seals)
• Conditions: Proper installation and usage according to our guidelines
• Process: Contact us with photos/videos of the issue

"We've been using YIDI Motion's linear rails in our CNC machines for over 2 years. The precision and durability are comparable to the German brands we used before, but at 40% lower cost. Their technical team helped us select the right rail size for our application, and the delivery was on time every time. Highly recommended!"

Maria Garcia, Automation Engineer at RoboTech Solutions, Spain

★★★★★

"YIDI Motion's custom linear rails saved our project. We needed a specific width and hole pattern that no other supplier could provide without a massive MOQ. They manufactured exactly what we needed in just 6 weeks, and the quality was excellent. Their DLC-coated rails have performed flawlessly in our harsh operating environment."

Chen Wei, Purchasing Director at Shenzhen Electronics Co., China

★★★★☆

"We switched from a local supplier to YIDI Motion and saw immediate improvements in quality and consistency. Their ISO 9001 certification gives us confidence in their processes. The only reason I'm not giving 5 stars is that their lead times can be a bit long for custom orders, but the quality is worth the wait."

David Kim, CEO at MedTech Innovations, South Korea

★★★★★

"For our medical devices, we need ultra-precise and reliable components. YIDI Motion's cleanroom-compatible linear rails have exceeded our expectations. They provided all the necessary FDA compliance documentation, and their stainless steel rails have shown no signs of corrosion in our sterilization processes. Excellent service and support!"

Anna Schmidt, Operations Manager at AutoParts GmbH, Germany

★★★★★

"We were skeptical about switching from our long-time German supplier, but YIDI Motion proved us wrong. Their rails are just as precise (if not more so) and the cost savings have been significant. The CE certification gave us the confidence to try them, and we haven't looked back. Their 24h response time is also a big plus compared to our previous supplier."
