Senior Engineer, Tesla

"YIDI’s ball screw actuators exceeded our torque requirements for the Model Y assembly line. Their OEM team delivered prototypes in 10 days – unheard of in this industry."

Dr. Lena M.

R&D Director, Siemens Healthineers

"The ±0.005mm repeatability of YIDI’s actuators was critical for our MRI calibration systems. Their FDA-approved materials gave us peace of mind for medical compliance."

Carlos R.

Procurement Manager, Bosch Rexroth

"Switching to YIDI reduced our actuator costs by 22% without sacrificing quality. Their just-in-time delivery keeps our production lines running smoothly."

❓ What’s the difference between a ball screw and lead screw actuator?

Ball screws use recirculating ball bearings to eliminate friction, offering 90-95% efficiency, higher precision (±0.01mm), and longer lifespan (10M+ cycles). Lead screws rely on sliding contact, with 60-70% efficiency, lower precision (±0.5mm), and shorter lifespan (1M cycles). For high-load or high-precision applications, ball screw actuators are the superior choice.

❓ Can YIDI customize a linear ball screw actuator for my specific application?

Absolutely. We offer full OEM/ODM services, including:

• Custom screw diameters (6-63mm) and leads (1-20mm).
• Special materials (stainless steel, hardened steel, or corrosion-resistant coatings).
• Unique stroke lengths (up to 3000mm).
• Integrated sensors (encoders, limit switches, or temperature probes).
• Environmental adaptations (IP65+ sealing, food-grade lubrication, or cleanroom compatibility).

Submit your requirements here, and our engineers will provide a free design consultation.

❓ How fast can YIDI deliver custom linear ball screw actuators?

Our 15-20 day lead time is among the fastest in the industry, thanks to:

• In-house manufacturing with German/Japanese CNC machines.
• 100-employee team (30% senior technicians).
• Pre-engineered modular designs for rapid customization.
• 24/7 expedited shipping for urgent orders (additional fees apply).

For standard models, we can ship within 3-5 days.

❓ What’s the maximum load your linear ball screw actuators can handle?

Our standard models support loads from 500N to 8000N. For heavier applications, we offer:

• Double-nut preloaded designs for up to 15,000N.
• Tandem arrangements (multiple screws in parallel) for 20,000N+.
• Custom ball nut materials (e.g., bronze or steel) for extreme loads.

Note: Load capacity depends on screw diameter, lead, and speed. Always consult our engineering team for your specific use case.

❓ Do you provide samples for testing?

Yes! We offer free samples for qualified customers (minimum order value applies). Here’s how it works:

1. Submit your technical requirements via our contact form.
2. Our team will select the best match from our inventory or propose a custom design.
3. We’ll ship a sample within 5-7 days (express shipping available).
4. Test the sample in your application. No obligation to purchase.

Pro Tip: Ask for our performance data sheets to compare our actuators against your current solution.

❓ What payment methods and logistics options do you accept?

Payment Methods:

• TT (Telegraphic Transfer) – 30% deposit, 70% before shipment.
• Letter of Credit (L/C) – For orders over $50,000.
• PayPal – For samples and small orders.
• Western Union – For urgent payments.

Logistics Options:

• Air Freight (DHL, FedEx, UPS) – 3-7 days.
• Sea Freight – 20-40 days (cost-effective for bulk orders).
• Express Train (China-Europe) – 12-15 days.

❓ What’s your warranty and after-sales service policy?

We stand behind our linear ball screw actuators with:

• 2-Year Warranty against manufacturing defects.
• Lifetime Technical Support – Our engineers are available for troubleshooting.
• Free Replacements for defective units (verified by our QC team).
• On-Site Training for complex installations (additional fees may apply).

Note: Warranty does not cover misuse, improper installation, or wear-and-tear. Always follow our installation guidelines.

★★★★★

"We replaced our hydraulic cylinders with YIDI’s linear ball screw actuators in our packaging line. The energy savings alone paid for the upgrade in 6 months. Plus, the precision improved our product consistency by 25%."

Sophie L.

R&D Engineer, Germany

★★★★★

"YIDI’s custom YDA-2010 actuators with IP67 rating were perfect for our outdoor robotics project. They’ve survived -20°C to 80°C without a single failure in 18 months. The CE certification made our compliance process seamless."

David K.

Production Director, Canada

★★★★☆

"The lead time was impressive – we received our custom actuators in 18 days. The only reason I’m not giving 5 stars is that the initial quote was slightly higher than competitors. But the quality and service more than made up for it."
