Ball Screw Quality Control, Inspection Reports, and Export Packing
Industrial buyers need more than a low price. They need confidence that the screw matches the drawing, the nut movement is acceptable, and long parts will arrive protected.
Dimension Inspection
Check total length, thread length, journal diameter, thread, shoulder, groove, and coupling-side dimensions.
Movement Check
Review nut movement, backlash or preload requirement, noise, and assembly fit according to the application.
Shipment Records
Provide product photos, packing photos, labels, and shipment details for buyer documentation.
Process evidence
Quality and packing process
Quality control should connect inspection, cleaning, rust prevention, packing, and shipment records. Buyers can state in the RFQ which inspection photos, packing photos, or label details are needed.
Inspection confirmation
Check total length, thread length, end dimensions, nut movement, appearance, and buyer-specific requirements.
Cleaning and rust prevention
Clean surface residue before shipment, apply rust prevention according to transport and storage time, and protect threads and machined ends.
Packing and shipment records
Long parts need support and fixing to reduce bending and impact risk. Labels, packing photos, and shipment records can be provided when requested.

Long ball screws need protection against rust, impact, and bending.
Export packing should match length, weight, transport method, and customer requirements. For long screws, the package must support the part, not only cover it.
- Apply rust prevention according to shipment and storage needs.
- Protect thread and machined ends from impact.
- Use hard tubes, cartons, or wooden cases depending on length and order size.
- Fix long screws to reduce bending risk during transport.
- Send packing photos before shipment when requested.

Quality and Packing FAQ
Quality and packing requests should be stated during RFQ, before inspection or label requirements appear at shipment time.
What inspection and packing confirmation can be provided?
We can discuss inspection, cleaning, rust prevention, packing, and shipment photos, including total length, thread length, end dimensions, nut movement, appearance, and export packing status.
What matters for exporting long ball screws?
Long parts need rust prevention, impact protection, and bending prevention. Packing should match length, weight, transport method, and quantity, using hard tubes, cartons, or wooden cases as needed.
Can labels or shipment photos follow customer requirements?
Yes. Label content, carton marks, batch information, and shipment photo requests should be discussed during RFQ so the quotation and shipping records stay consistent.
How do you keep repeat orders consistent?
Repeat production follows the confirmed drawing revision, specifications, accuracy grade, and inspection standards. Each batch is checked against the order for inspection results, labels, batch information, and shipment photos, so reorders stay on the same specification.
