Sourcing a Single 1 Ball Screw? Here's What You Need to Know Up Front
Procurement managers often hit a snag when they need just one ball screw for a prototype, repair, or urgent replacement. Overseas suppliers balk at small orders, lead times drag on, and quality? That's a gamble. We've handled this exact scenario hundreds of times at YIDI Motion.
Established in 2020, Hebei YIDI Import and Export Trading Co., Ltd. specializes in linear motion components like ball screws, linear guides, and actuators. Our factory team of 100, with over 30% senior technicians, runs German and Japanese imported machines. We export to 50+ countries, including the US, Germany, and Japan. For your 1 ball screw, we offer rolled and ground options in SFU, DFU series—ready to ship small quantities without minimums eating into your budget.
Think about your last machine downtime. A seized ball screw costs hours, maybe days. We get it. That's why we stock common sizes: 16mm to 50mm diameters, leads from 5mm to 20mm. C5 to C3 accuracy classes. Preloaded nuts for zero backlash if rigidity matters. No fluff—just reliable parts that fit CNC mills, robotic arms, or semiconductor tools.
US importers appreciate our DDP shipping to major ports like LA or NY. Duties handled, tracking real-time. One buyer from Texas swapped a failing domestic screw; our replacement cut friction losses by noticeable margins, extending life past 10,000 hours under load. We're not guessing; these are field reports from repeat customers.
Short on time? Email adam@yidimotion.com or call +86 18134111662. We'll spec it out, quote factory-direct pricing, and confirm stock. No sales pressure, just straightforward supply.
Ball screws aren't commodities. Poor recirculation design leads to brinelling. Inconsistent preload? Whipping under dynamic loads. Our engineering team stress-tests every batch. For single units, we pull from inspected inventory, laser-etch lot numbers for traceability.
Compare that to Alibaba roulette. We've seen importers burn cash on undersized balls or soft shafts. YIDI's got the metrology—Renishaw gauging, constant temperature rooms—to hit DIN/ISO specs. Your project demands precision; we deliver it, one screw at a time.
Inside a Ball Screw: Engineering Details That Matter
Start with the basics, but don't skim. A ball screw converts rotary torque to linear thrust via recirculating steel balls. Unlike Acme leadscrews, friction drops to 1-3%—critical for energy efficiency in servo-driven axes.
Shaft: Typically SCM415 alloy, induction hardened to HRC58-62. Ground versions use cylindrical or gothic arch grooves for higher load capacity. Rolled? Cold-formed for cost savings, still good for most automation up to 50m/min speeds.
Nut design varies. Single-nut for compact setups, but watch for axial play. Double-nut or preloaded flanged nuts lock it down. Ball diameters? 3.175mm to 9.525mm common, affecting DN value (pitch dia x rpm limit).
Critical speed formula: n = (C L / D^2) where L is unsupported length. Exceed it, and you get vibration. We calculate this per order. Accuracy? C10 sloppy for positioning; C3 for micron-level repeatability in EDM machines.
Here's a quick spec table for our popular 1 ball screw options:
| Model | Dia x Lead (mm) | Accuracy | Dyn Load (kN) | Length (up to m) |
|---|---|---|---|---|
| SFU1605 | 16x5 | C7 | 18.4 | 1.5 |
| SFU2005 | 20x5 | C5 | 22.5 | 2.0 |
| SFU2510 | 25x10 | C3 | 30.1 | 3.0 |
| DFU3205 | 32x5 | C5 | 45.2 | 4.0 |
| SFU4010 | 40x10 | C7 | 60.3 | 5.0 |

Custom lengths? No issue. Ends machined to your drawing—fixed or floating. Seals prevent contaminant ingress; wipers standard on flanged nuts.
One oversight: lubrication. Grease-packed for life, but high-speed apps need oil mist. We've seen nuts gum up from wrong lube—stick to lithium complex NLGI 2.
Preload matters. Light for smooth motion, heavy for stiffness. We adjust via oversize balls or spacer rings. Test it yourself: feel the difference in no-load torque.
Where 1 Ball Screw Shines in the Field
CNC routers. Z-axis positioning demands repeatability. Our C5 screws hold 0.005mm over 300mm travel.
Industrial robots. Joint actuators need compact power. 20mm dia ballscrews pack 20kN thrust in short strokes.
- Semiconductor wafer stages: Ultra-clean, low particle generation.
- Medical devices: Sterilizable 316SS shafts available.
- 3D printers: Budget rolled screws suffice for hobby-to-pro.
- Packaging machines: High-cycle indexing, 100m/min capable.
- Testing equipment: Fatigue-rated for dynamic loads.
Contractors in the US often spec these for retrofits. One outfit in Ohio replaced sliding ways; travel time dropped, power draw too.
Logistics note: Vertical apps? Use anti-rotation pins. We've shipped to solar tracker installs—outdoor exposure tests corrosion resistance.
Smart Procurement for Your 1 Ball Screw Order
Risks abound. Underspec diameter? Buckling. Wrong lead? Torque spikes. Measure your bore first.
Steps we follow with buyers:
- Define load/speed. Use our calc sheet.
- Select accuracy. C7 everyday; C3 precision.
- Choose nut: Flange for mounting ease.
- Length + ends. BK/BF supports common.
- Quote includes wipers, grease.
Shipping to USA: Air for urgency (7-10 days), sea for value (25-35 days DDP). One 1 ball screw? Fits FedEx envelope.
OEM/ODM? Fully custom. Private label your brand on the nut. We've done it for EU automation firms.
Tip: Verify supplier metrology. Ask for grind charts. YIDI provides them free.

Feedback from Procurement Pros
Mike R., Operations Manager, Texas CNC Shop
"Needed one 25x10 ball screw ASAP for a Haas mill. YIDI shipped DHL, arrived perfect. C3 accuracy spot-on, no break-in needed. Will order guides next."
Sarah L., Procurement Lead, California Robotics Firm
"Prototype run required custom preload nut. Adam sorted specs fast, quoted fair. Quality beat THK samples. Logistics smooth to SFO."
Tom K., Project Engineer, Ohio Automation
"Replaced worn 32mm screw. YIDI's double-nut held better under 5kN. Traceability docs helped QA pass. Good partner for small runs."
David W., Supply Chain Director, Florida Medical Devices
"Single unit for R&D. SS option corrosion-free. Fast turnaround, competitive vs US vendors. OEM labeling next project."
