The Hidden Costs of Subpar Linear Motion
Your production line stops every 3 hours for adjustments. That's 25% downtime you can't afford. Standard lead screws buckle under long travels, causing:
- Premature wear: Traditional screws degrade 40% faster in extended applications (>2m)
- Positioning errors: ±0.3mm inaccuracies from thermal expansion in uncompensated designs
- Speed limitations: Critical velocity constraints reduce your machinery's potential by 35%
What Your Machinery is Missing
Long ball screws solve these issues but come with their own challenges:
| Challenge | Impact | YIDI Solution |
|---|---|---|
| Critical speed limitations | Reduces max RPM by 40% | Optimized ball circulation design |
| Deflection under load | Causes positioning errors | Pre-loaded double nut systems |
| Thermal expansion | ±0.5mm dimensional changes | Temperature-compensated materials |

YIDI Motion's Long Ball Screw Solutions
Unmatched Precision for Extended Lengths
Our C5-grade long ball screws maintain ±0.005mm/m positioning accuracy even at 6-meter lengths. The secret:
- German-ground threads: Surface finish Ra <0.2μm reduces friction by 20%
- 100% pre-load testing: Each screw undergoes 2x rated load validation
- Patented ball return: 30% smoother operation than standard designs
Built for Heavy-Duty Industrial Applications
From CNC routers to semiconductor equipment, our screws handle:
vs. 25kN industry average
30% faster than competitors
2x longer service life
Industrial-grade stability

Frequently Asked Questions
About Long Ball Screws
Q: What's the maximum length you can manufacture?
A: Our standard production goes up to 6 meters. For custom applications, we've delivered screws up to 12 meters using our continuous milling process. Lengths beyond 8m require special logistics arrangements.

Q: How do you prevent buckling in long screws?
A: We address this through:
- Optimized slenderness ratio (max 60:1)
- Intermediate support designs for lengths >4m
- High-strength 50CrMo4 or S55C materials
- Dynamic load calculations for each application
Customization & Ordering
Q: Can you match a competitor's design?
A: Yes. As an OEM/ODM specialist, we can reverse-engineer existing screws or work from your CAD models. Our team has replicated designs from THK, NSK, and Bosch Rexroth with 99.8% dimensional accuracy.
Q: What's your lead time for custom orders?
A: Standard custom screws (lengths <4m): 15-20 working days. Complex orders (special materials, lengths >6m): 4-6 weeks. We maintain a 10,000m inventory of semi-finished products to accelerate production.
Technical Support
Q: Do you provide installation guidance?
A: Absolutely. We offer:
- 3D models and assembly drawings
- Video tutorials for mounting and pre-loading
- On-site support for first-time installations (additional cost)
- Lubrication recommendations for your specific environment
Q: How do I calculate the required screw size for my application?
A: Use our online calculator or provide these parameters:
- Required travel length and positioning accuracy
- Load requirements (dynamic and static)
- Speed and acceleration needs
- Environmental conditions (temperature, contaminants)
- Mounting orientation (horizontal/vertical)
Our engineers will recommend the optimal specification within 24 hours.

What Our Customers Say
Texas, USA
"We were skeptical about switching from our US supplier, but YIDI's long ball screws not only matched the quality but reduced our costs by 30% without compromising performance. The 4-week delivery was faster than our previous supplier's 8 weeks. Highly recommend for anyone looking for reliable long-travel solutions."
Purchased: 50x 4m C5-grade screws | Savings: $12,000/year
Berlin, Germany
"The technical support from YIDI was exceptional. They helped us optimize our design for a 7-axis robot, suggesting a double-nut configuration that eliminated backlash in our prototype. Their screws have been running 24/7 for 18 months without any issues."
Purchased: 20x custom 3.2m screws | Application: Robotic assembly
Seoul, South Korea
"Our solar tracking systems require high durability in extreme weather. YIDI's corrosion-resistant long ball screws have zero failures in 2 years of operation across 15 installations. Their ability to provide complete documentation for our ISO 9001 audits was a major plus."
