How to Store Ball Screws and Prevent Rust

Bar stock mainly risks rust and bending

Ball screws are usually long. If support is poor, humidity is high, or packing is damaged, rust, bending, or surface damage can occur. Distributor stock should treat rust prevention and support as basic requirements.

Check five things on arrival; missing one compounds later:

Packing damage: a torn outer wrap, a dented hard tube or water in a wooden case should be recorded and handled on the spot, not traced back after the goods are put away.
The rust-prevention layer: check that the oil film or bag is intact and not dried out or wiped away.
Support arrangement: whether long parts sit horizontally on multiple support points with no unsupported span.
Label records: model, length, nut quantity and batch all present.
Warehouse humidity: control relative humidity and avoid condensation; set the threshold from the rust-prevention product supplier's guidance and the local climate.

Labels prevent model mix-ups

Models such as 1605, 1610, 2005, and 2510 can look similar. Without clear labels, warehouses and customers can mix them up. Keep model, length, nut quantity, and batch on packing and records.

Zoning by model beats stacking by arrival date: gathering one model together stops pickers choosing by lookalike wrapping, and makes stock counting easier.

Storage affects later machining

If the bar will later be cut or end machined, straightness and surface condition matter. Long-term stock should avoid side pressure, unsupported spans, and humid environments.

Support points follow the length, with support at both ends and in the middle; keep long parts off the floor so ground moisture does not attack the packing directly. Bars approaching the protection period stated by the product supplier should be re-inspected and re-coated as needed — rust prevention has a service life, it is not applied once and forgotten.

RFQ checklist

Confirm anti-rust oil, bag, or other protection.
Support long bars horizontally and avoid local hanging.
Record model, length, nut, and batch on labels.
Use FIFO management to reduce long storage time.

FAQ

Can original bars be stored long-term in the arrival packing? Not directly. First check packing damage, rust protection, support method, label records, and warehouse humidity, then manage stock by FIFO to reduce rust, bending, and model mix-up risks.

How long does the protection last? Rust prevention has a service life: choose it for the transport and storage period, then re-inspect and re-coat. Check stock once it approaches the period the product supplier states.

Can slightly rusted stock still be used? It depends on the location and depth. Flash rust on the threaded section or on fitting surfaces (journals, bearing seats) cannot simply be wiped off — assess it before deciding whether to downgrade the part.
