Running a CNC shop or automation line? When your ball screws start binding or the nuts wear out prematurely, production grinds to a halt. We've seen it happen too often – a small oversight in sourcing leads to weeks of downtime. At YIDI Motion, part of HEBEI YIDI IMPORT AND EXPORT TRADING CO.,LTD., we handle ball screw and nut service end-to-end. From precision repair to full custom builds.
Established in 2020, our Shijiazhuang-based operation focuses on linear motion components. Ball screws. Nuts. Guides. Splines. All backed by a 100-person factory team where senior techs make up over 30%. We pull in German and Japanese equipment for grinding and assembly, ensuring tolerances that hold up in demanding setups.
Exports hit 50+ countries already – Germany, USA, Canada, you name it. Phone us at +86 18134111662 or email adam@yidimotion.com. We're geared for OEM/ODM, one-stop sourcing. No middlemen fluff.
Procurement managers tell us they chase lead times under 4 weeks. We deliver. Custom ball screw and nut service? Starts with your specs, ends with tested parts on your dock.
Think about your last screw failure. Was it preload loss? Contamination? Off-spec leads? We diagnose and fix. Or build new to dodge the headache altogether.

Sourcing ball screws and nuts internationally isn't straightforward. Importers from the US often trip over quality inconsistencies. A nut that looks fine on paper fails after 5,000 hours.
Lead times stretch because factories overseas overload on standard SFU sizes, ignoring your DFI custom needs. Then there's logistics – FOB Qingdao quotes turn into headaches with demurrage fees.
- Undisclosed material flaws: Chrome steel advertised as hardened, but micro-cracks show under load.
- Accuracy mismatches: C7 promised, C10 delivered – your positioning drifts.
- Nut preload drift: Double nuts loosen, single nuts bind.
- Export compliance snags: Missing ROHS or CE docs halt customs.
- MOQ traps: 10 pieces minimum? Not if you're prototyping.
One operations manager shared how a cheap Taiwanese supplier botched a batch – backlash jumped to 0.01mm. Cost him $20k in scrapped fixtures. Avoid that. Vet for ISO 9001, in-house grinding.
Our advice? Demand dynamic balance tests and preload verification reports. It's standard here.
How Our Service Tackles Your Needs
We offer full ball screw and nut service: repair, reconditioning, replacement, and custom fab. Start with a faulty unit? Send it over. We disassemble, inspect balls and races, re-lube or replace.
Precision ground screws for high-speed apps. Rolled for cost-sensitive volume. Nuts in flange, block, or miniature configs. Materials? Carbon steel, stainless 440C, even PEEK for cleanrooms.
Customization flows like this: You spec diameter (12-80mm), lead (2-20mm), length up to 6m. We quote within 24 hours. Prototypes in 2 weeks, production scales fast.
- Repair: Clean, inspect, preload reset – 70% cost savings vs. new.
- Nut replacement: Ball recirculating types, extended life.
- Custom assembly: End wipers, seals, flanges to your drawing.
- Tech support: Free CAD models, preload calcs.
Conversion tip: Pair with our linear guides for matched systems. Reduces alignment issues.
Engineers note better rigidity in our double-nut setups for vertical loads. Seen it cut vibration in pick-and-place robots.

Alignment is king. Use laser tools for parallelism under 0.02mm/300mm. Preload nuts to 3-5% of load rating.
Lube every 3000km or quarterly. Grease points: Every 100 hours initial.
Warning: Dust seals fail first. Inspect visually. Binding? Check ball recirculation paths.
- Mount fixed end first.
- Torque to spec (varies 20-100Nm).
- Run-in at low speed.
- Monitor temp rise <30C.
We've retrofitted shops where poor install doubled wear. Pro tip: Fixed-floating setup for long spans.
