How to Pack Long Ball Screws for Export: Rust Prevention

Long parts are more than wrapped

The longer a ball screw, the higher the risk of bending, impact damage, and rust in transit. The packing plan follows length, weight, quantity, transport mode, and the customer's receiving requirements.

Length sets the first tier: up to about 1 m a carton works for short, light standard parts; 1–3 m normally goes in a hard tube, which suits a single part or a few long pieces; beyond 3 m or stacked shipments need a wooden case with several support points. That tier decides everything downstream.

Buyer decision table

Packing risk	Recommended control	When to request it
Rust	Anti-rust oil, sealed wrapping, desiccant if needed	Sea freight, humid destinations, long storage.
Bending	Hard tube, wooden case, inner supports	Long screws or thin diameters.
Impact	End protection, foam, fixed inner brackets	Mixed cargo or long-distance transport.
Resale handling	Neutral labels, carton marks, shipment photos	Distributor stock or customer-facing delivery.

Protect the thread and the machined ends

The threaded section, the nut, the journals, keyways and threaded ends all have to avoid impact. Once the ends are machined, their protection and fixing matter most: journals and bearing seats are fitting surfaces, and a bruise means the support unit will not fit — damage that is usually discovered at assembly.

The nut needs fixing too, so it cannot slide along the screw in transit and hit an end. Solid-wood packing for export also needs its ISPM 15 heat treatment or fumigation confirmed; plywood cases are normally exempt.

Leave evidence before shipment

For distributors and industrial customers, product photos, label photos, carton marks, and packing photos support receiving and after-sales discussions. For bar stock, see how to store ball screws and prevent rust; for how to check the photos, see how to check shipment photos for long ball screws.

RFQ checklist

Confirm model, length, quantity, and whether screws ship as bars, sets, or machined parts.
State destination country, transport mode, and expected storage time after arrival.
Request hard tube, wooden case, anti-rust treatment, neutral labels, or carton marks as needed.
Ask for pre-shipment photos showing labels, protection, wooden case, and full package length.
Tell weimute if the packing must meet your distributor or end-customer standard.

Send us your packing requirements

Send weimute your length list, destination, transport mode, and packing rules before quotation. Our manufacturing and sales team will separate product price from export packing cost so the offer is easier to compare — if the difference comes from packing rather than the screw, you can see it on the line items.

FAQ

Is a wooden case always necessary? Not always. It depends on length, diameter, transport mode, and handling risk. For stock and storage, see how to store ball screws and prevent rust.

How many support points are needed? Place them along the length, with support at both ends and in the middle, so no long span is left unsupported. The layout follows diameter and length; thin long parts need closer spacing.

Why quote packing separately? Separate lines make it clear whether a price difference comes from the screw itself or from export protection, so changing the packing does not break the comparison.
