⚠️ Premature Wear & Tear

Low-quality linear track bearings degrade quickly under heavy loads or high-speed operations, leading to costly downtime. Our bearings use German/Japanese-grade steel and precision grinding for 3x longer lifespan.

⚠️ Inconsistent Precision

Misalignment or poor tolerances cause vibrations and inaccuracies in CNC machines. YIDI’s bearings achieve ±0.005mm repeatability with rigid rail designs and recirculating ball technology.

⚠️ Limited Customization

Off-the-shelf solutions rarely fit unique applications. We offer OEM/ODM services—custom lengths, materials (stainless steel for corrosion resistance), and load ratings tailored to your needs.

Why Choose YIDI?

• High-Speed Capability: Tested up to 10 m/s with minimal noise (≤50 dB).
• Heavy-Duty Loads: Dynamic load ratings from 5,000N to 50,000N.
• Corrosion Resistance: Optional stainless steel (SS304/316) for harsh environments.
• Easy Installation: Compatible with THK, HIWIN, NSK rail systems (interchangeable designs).
• Cost Savings: 30% lower prices than European brands with same-day shipping for stock items.

❓ What’s the difference between linear track bearings and linear bushings?

Linear track bearings (like ours) use recirculating balls for higher load capacity and precision, while bushings rely on sliding contact, offering lower friction but less rigidity. Track bearings are ideal for high-precision applications like CNC machines.

❓ Can YIDI bearings replace THK or HIWIN parts?

Yes! Our linear track bearings are designed with interchangeable dimensions to fit THK, HIWIN, and NSK rails. We provide CAD models for easy integration. Contact us for a compatibility check.

❓ What’s the lead time for custom orders?

Standard products ship in 5-7 days. Custom OEM/ODM linear track bearings (e.g., special lengths, materials) take 15-20 days. Expedited options are available—inquire now.

❓ Do you offer samples for testing?

Absolutely! We provide free samples for most linear track bearing models (shipping costs may apply). Request yours via our contact form.

❓ How do I maintain my linear track bearings?

For optimal performance:

1. Clean rails and bearings monthly to remove debris.
2. Re-lubricate every 6 months (or 2,000 km of travel).
3. Check for misalignment or unusual noise.
4. Avoid exposure to water or corrosive chemicals unless using stainless steel models.

❓ What payment methods do you accept?

We support TT (Bank Transfer), L/C, PayPal, and Western Union. For new customers, we require 30% deposit with the balance due before shipment. O/A terms are available for long-term partners.

❓ Do you provide installation support?

Yes! We offer:

• Detailed installation manuals (PDF + video).
• Remote technical support via WhatsApp/email.
• On-site training for bulk orders (additional fees may apply).

Mark Johnson

CNC Shop Owner, Texas, USA

"Switched from THK to YIDI for our Haas mills. The LTB-25 bearings cut our maintenance costs by 40% with zero drop in precision. The 30% savings went straight to our bottom line. Highly recommend!"

Sophie Leclair

Automation Engineer, Lyon, France

"YIDI’s stainless steel linear track bearings were the only ones that held up in our food-packaging line. Other brands corroded within months. Their team also helped us customize the rail length—service was flawless."

Raj Patel

Robotics Startup CEO, Bangalore, India

"As a startup, budget was tight. YIDI’s LTB-15 bearings gave us THK-level precision at half the cost. Their OEM support let us iterate quickly. Now we’re scaling production!"

Carlos Mendoza

Maintenance Manager, Mexico City, Mexico

"Our old bearings failed every 6 months in the high-dust environment of our cement plant. YIDI’s sealed LTB-35 bearings have lasted 18+ months so far. The free sample convinced us—now we’re a repeat customer."
