1. Backlash and Precision Loss: Traditional lead screws introduce play over time, causing ±0.1mm positioning errors in CNC machines. For aerospace or medical devices, this means failed quality inspections and costly rework.
2. Premature Wear in Harsh Environments: Standard carbon steel screws corrode in humid or chemical-exposed settings, reducing lifespan by 40-60%. Factories in coastal regions or food processing plants face frequent replacements.
3. Supply Chain Bottlenecks: Lead times from European or Japanese suppliers often exceed 12-16 weeks. Delayed deliveries halt production lines, costing manufacturers $10,000+/day in downtime.
“We switched to YIDI Motion after a 3-month delay from our German supplier. Their 4-week delivery and ISO 9001-certified screws saved our automation project.” — Mark T., Operations Director at AutoTech LLC

5 Key Advantages of YIDI Motion Ball Screws
- German/Japanese Machinery Precision: Ground ball screws achieve 98-99% efficiency vs. 70-80% for lead screws, reducing motor power requirements by 30%.
- Zero Backlash Design: Preloaded nuts eliminate play, ensuring ±0.01mm repeatability for semiconductor and optical applications.
- Corrosion Resistance: Stainless steel (AISI 440C) or DLC coating options for marine, medical, or food-grade environments.
- High Load Capacity: Dynamic load ratings up to 100 kN—ideal for heavy-duty presses and CNC routers.
- China’s Supply Chain Agility: 50% faster delivery than European/Japanese suppliers with no compromise on quality (ISO 9001, CE, RoHS certified).

Case Study: 40% Cost Reduction for a U.S. CNC Manufacturer
Client: Precision Machining Inc. (Texas, USA)
Challenge: High costs and long lead times from a Japanese supplier for 25mm x 10mm pitch ball screws (annual volume: 500 units).
YIDI Solution:
- Supplied rolled ball screws with C5 accuracy at $150/unit (vs. $280 from the incumbent).
- Reduced lead time from 14 weeks to 5 weeks using our Shijiazhuang factory’s vertical integration.
- Added custom end machining to match their existing mounting system.
Result: $65,000 annual savings with zero compromise on performance. The client expanded orders to include linear guides in 2025.

FAQ: Procurement, Customization & Support
How do I choose between rolled and ground ball screws?
Rolled ball screws are cost-effective (30-50% cheaper) and suitable for 80% of industrial applications (e.g., packaging machines). Use ground ball screws for high-precision needs (CNC, aerospace) where ±0.005mm/300mm accuracy is required.
What’s the minimum order quantity (MOQ) for custom ball screws?
Standard sizes: 10 units MOQ. For custom diameters/lengths: 50 units. Prototyping available for 1-2 samples (lead time: 10-15 days).

Do you offer ball screw nut assemblies?
Yes! We provide preloaded nuts (single/double), flanged nuts, and anti-backlash nuts for high-precision applications. All nuts undergo 100% inspection for torque consistency.
How do I calculate the lifespan of a ball screw?
Use the formula: L10 = (C / F)³ × 10⁶ revolutions, where C = dynamic load rating (N) and F = applied load (N). For example, a 25mm screw (C=45kN) with a 10kN load lasts ~337 million revolutions (~10,000 km travel).
What payment terms do you accept?
TT (30% deposit, 70% before shipment), LC at sight, or PayPal for samples. For long-term partners: 60-day OA terms (subject to credit approval).
Do you provide installation support?
Absolutely. We offer:
- Free CAD/STEP files for your design team.
- Video tutorials on alignment and preloading.
- On-site training (for orders >$50,000; travel fees apply).
Limited-Time Offer: 10% Discount on First Order
Order 50+ ball screws before June 30, 2026 and receive:

What Our Clients Say
“Upgraded my Haas VM-2 with YIDI’s 16mm x 5mm ground ball screws. Surface finish improved from Ra 0.8 to Ra 0.4, and my spindle life doubled. The DLC coating handled coolant splashes like a champ. 5/5 stars.”
“Needed zero-backlash screws for a pick-and-place robot. YIDI’s C3-grade screws with preloaded nuts delivered ±0.008mm repeatability. Their German-language support was a game-changer for our team.”
“Switched from a local supplier to YIDI for 25% cost savings on 40mm heavy-duty screws. The only downside? Customs took 5 extra days—but their FOB pricing still beat everyone else. Will order again.”
