How to Check Shipment Photos for Long Ball Screws

Shipment photos should verify the order

Shipment photos should not be only one picture of a box. Buyers should be able to check model, length, quantity, nut quantity, label content, and packing condition. Distributor orders should also confirm customer labels and carton marks.

Product and label photos should be separate

Ask for product photos, label photos, carton marks, end protection photos, bending prevention support photos, and packing photos. For long ball screws, check whether support positions are enough and whether the ends and nuts are fixed.

Packing photos reveal transport risk

Packing photos can show whether the carton, hard tube, or wooden case has internal support, whether the product can move, whether the ends may be hit, and whether long parts have bending prevention support. Quantity check photos also help pre-shipment records.

RFQ checklist

Product photos: full part, ends, nut, machined positions, and appearance.
Label photos: model, length, quantity, batch, customer labels, and carton marks.
Packing photos: end protection, bending prevention support, packing photos, and sealed carton condition.
Quantity check: quantity per carton, total cartons, nut quantity, and split shipment status.

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.
