Precision Ball Screw Manufacturer & OEM Supplier | YIDI Motion
Ball Screw Manufacturer - Precision OEM/ODM Supplier for CNC & Automation | YIDI Motion
Meta Description: Trusted ball screw manufacturer offering precision ground and rolled ball screws for linear motion systems. OEM/ODM services, ISO certified factory in China exporting to USA, Europe. Fast quotes, custom specs, reliable lead times for procurement managers.
As a procurement manager sourcing ball screws for your CNC retrofit or automation line, you know the headaches. Lead times stretch out. Quality varies wildly between suppliers. And when a screw binds or preloads wrong, downtime hits hard—often thousands per hour.
We've shipped over 100,000 units to U.S. integrators since 2020. Not hype. Just steady deliveries from our Hebei factory. YIDI Motion specializes in ball screws that actually perform under load, without the fluff.
Picture this: your last supplier quoted low but delivered C7 accuracy when you needed C5. Balls chipped after 5,000 hours. We hear that weekly. Our ground ball screws hit C3-C5 consistently, backed by German-imported grinders.

1. Why Procurement Risks Eat Into Your Margins
Specifying ball screws isn't just picking a diameter. Get the lead wrong, and your actuator speed tanks. Overspec on preload, and friction eats power.
Common pitfalls we've seen: Importers chase rock-bottom FOB prices from unverified Alibaba listings. Result? Rolled screws pass as ground. Accuracy drifts. One U.S. robotics firm lost a $200k contract after failures.
Then logistics. 20ft containers stuffed wrong lead to customs holds. Delays from 45 days to 90. We've optimized packing—1,200 SFU1600s per 40ft HQ, fully insured.
Another: No preload matching. Buyers order standard nuts, but forget dynamic/static load mismatch. Balls skid. Life halves. We match nuts to screws per ISO 3408.
2. How Our Ball Screws Solve Real-World Problems
Our lineup covers rolled for budget linear modules, precision ground for high-speed CNC. Diameters from 12mm to 80mm. Leads 2mm to 32mm.
Take the SFU series—flanged nuts, easy mount. DFU for compact builds. Stainless options for washdown environments. No minimums on standard stock.
Custom? OEM/ODM full service. Last month, a German press brake maker needed C3, 50mm dia, left-hand thread. Delivered in 25 days. Tested to 10g accel.
Preload grades: Light to heavy. Reduces backlash to 3 microns. Users report 20-30% less vibration in Z-axis mills.
Short story: A Texas automation shop switched from a Taiwanese supplier. Their balls were undersized. Ours? Hit spec. Backlash near zero. They reordered 500 units.
3. Factory Deep Dive: What Sets Us Apart
HEBEI YIDI IMPORT AND EXPORT TRADING CO., LTD. Factory floor: 100 staff, 30% senior techs. Japan Okuma grinders. German DMG honeys. Full metrology lab—Renishaw probes.
Workflow: Bar stock in, heat treat, thread roll or grind, nut assembly, dyno test. 100% ball circulation check. No skips.
Export to 50+ countries. USA top market—automation boom. Canada robotics. France machine tools. Compliance nailed: REACH, RoHS.
One-stop linear motion: Ball screws pair with our guides, splines, modules. Procurement simplified. No chasing multiple VMI.
Scalable. From prototype 10pcs to 10k/month. Lead: Stock 3 days, custom 20-35. We've hit 15 for rush OEM.

Need ends machined? Ends E/F/G/H per DIN 69051. Nuts single/double. End wipers standard. Stainless 440C balls optional.
Pro tip: For vertical apps, specify higher preload. We've customized for 5g shock loads in packaging lines.
5. Applications Across Industries
- CNC mills/lathes: High rigidity, low backlash.
- 3D printers: Smooth, quiet motion.
- Robotics: Precision positioning.
- Medical devices: Cleanroom compliant.
- Semicon equip: Vacuum tolerant options.
Heavy duty? 63mm dia for injection machines. Tested 1M km life.
6. Installation and Maintenance Realities
Align shafts to 0.02mm/300mm. Pre-tension belts properly. Torque nuts to spec—overdo it, balls gall.
Lube: Grease every 100h light duty, oil mist for high speed. We've seen neglect cut life 50%.
Warning: Mismatched couplings vibrate. Use bellows or disc. Retrofits? Measure existing preload first.
7. Global Shipping and Lead Times
FOB Tianjin. DDP USA available. 40ft holds 2 tons. Tracking via sea freight forwarders.
USA: 28-35 days LCL, 20-25 FCL. Duties? Ball screws 8483.40 HS code, ~3.9%.
Rush? Air freight viable for samples. Get your shipping plan emailed today.

9. What Buyers Are Saying
Mark T., Procurement Mgr, Texas Automation: "Switched to YIDI after Taiwanese screws failed preload test. C5 accuracy spot on. Shipped 25 days to Houston. Reordering."
Sarah L., Ops Director, California Robotics: "OEM custom 40x10 left-hand. Matched our Rev C design perfectly. No recuts needed. Good comms with engineer Adam."
John R., Project Eng, Ontario CNC: "Rolled SFU for prototypes—quiet, no whip. Logistics smooth, cleared border fast. Price beat THK reseller."
Carlos M., Supply Chain, Florida Packaging: "Heavy preload for vertical lift. Held 2kN static. Maintenance interval doubled vs old stock."
10. Buyer FAQs
Q: What's the difference between rolled and ground ball screws?
A: Rolled cheaper, C7-C10 for general motion. Ground C3-C5 for precision/speed. We do both.
Q: MOQ for OEM?
A: 10pcs samples, 100+ production. Scales up.
Q: Can you match NSK/HIWIN specs?
A: Yes, reverse eng if needed. Provide drawings.
Q: Lead time to USA?
A: Stock 1wk, custom 4wks.
Q: Payment terms?
A: 30% TT advance, balance B/L copy. LC for big orders.
