How to Pack Long Ball Screws for Export

Long-part packing is not just wrapping

The longer the ball screw, the higher the risk of bending, impact damage, and rust during transport. Packing should match length, weight, quantity, shipping method, and receiving requirements.

Protect threads and machined ends

Thread areas, nuts, journals, keyways, and threaded ends should be protected from impact. After end machining, end protection and fixing are especially important.

Keep shipping evidence

For distributors and industrial buyers, product photos, label photos, carton marks, and packing photos help receiving and after-sales communication.

Confirm rust prevention and transport duration.
Support long parts to reduce bending risk.
Protect machined ends and nut positions from impact.
Provide labels and packing photos when required.

Typical buyer situations

This topic usually appears in distributor stocking, repair replacement, machine retrofit, automation projects, and drawing-based purchasing. If a buyer sends only one model number, the supplier cannot judge the real use, packing risk, or whether machining upgrades are needed.

Details to confirm before quotation

To reduce repeated questions, the RFQ should cover product specification, use case, and delivery expectations together. The following points can be copied into the RFQ form or email.

Purchase purpose: distributor stock, repair replacement, machine project, or sample testing.
Specification: diameter, lead, overall length, thread length, nut type, and quantity.
Machining: cut-to-length, end machining, and whether BK/BF, FK/FF, EK/EF, or other supports must be matched.
Delivery: target quantity, expected lead time, packing, labels, shipping method, and whether shipment photos are required.

Common mistakes

A common mistake is asking only for unit price without application, quantity, or packing details. Another is sending photos without dimensions. This turns quotation into guesswork and can create errors in end machining, nut matching, or long-part shipping.

Next step

If the specification is clear, submit an RFQ directly. If the model or accuracy grade is still uncertain, describe the machine use and old part details so the supplier can recommend a standard part, bar stock, cut-to-length, or end machining route.
