⚠️ 5 Critical Pain Points in Linear Motion Systems You’re Probably Facing
Purchasing managers and engineers in automation, CNC, and packaging industries often struggle with:
❌ High Costs from European/US Suppliers
Paying 30-50% more for branded linear guide rail & carriage assembly systems without added value. YIDI Motion offers equivalent quality at competitive prices.
❌ Long Lead Times (12+ Weeks)
Waiting months for deliveries slows down production. Our China-based supply chain ensures 4-6 week delivery for standard orders.
❌ Compatibility Issues
Off-the-shelf ball bearing linear guides don’t fit your machine’s specifications. We provide OEM/ODM customization for seamless integration.
❌ Inconsistent Precision
Poor tolerance control leads to ±0.05mm errors in CNC applications. Our German/Japanese equipment guarantees ±0.01mm accuracy.
❌ Lack of After-Sales Support
No technical backup for installation or maintenance. YIDI offers 24/7 engineering support and 1-year warranty.

❓ Frequently Asked Questions (FAQ)
➤ What’s the difference between ball bearing and roller bearing linear guides?
Ball bearing guides (e.g., YG-15, YG-25) offer high speed and low friction, ideal for light to medium loads. Roller bearing guides (e.g., YG-30, YG-45) provide higher load capacity and rigidity for heavy-duty applications.
➤ Can I get a sample before placing a bulk order?
Yes! We offer free samples for standard models (e.g., YG-15, YG-25). Custom samples may incur a fee, which is refundable upon bulk order. Contact us at adam@yidimotion.com.
➤ What’s the MOQ for OEM/ODM orders?
Our minimum order quantity (MOQ) is 50 meters for standard rails. For custom designs, MOQ starts at 100 meters. We also offer small-batch prototyping for R&D purposes.
➤ How do I choose the right linear guide for my CNC machine?
Consider these factors:
- Load Requirements: Dynamic/static load capacity (check our spec table).
- Precision Needs: SP-class for ±0.01mm, H-class for ±0.03mm.
- Speed & Acceleration: Ball bearings for high speed, rollers for high acceleration.
- Environment: Stainless steel for corrosive conditions.
- Space Constraints: Compact rails (YG-15) vs. heavy-duty (YG-45).
