How to State Lead Time in an Urgent Repair Ball Screw RFQ

State the real downtime first

An urgent repair ball screw RFQ should state whether the machine is stopped, the latest arrival date, split shipment acceptance, and shipping method. Saying only urgent is not enough for judging stock, cut length, or machining route.

Old part photos decide fast review

Old part photos should cover the full part, both ends, nut, flange, mounting holes, marking text, support unit, and coupling. Without a complete drawing, photos and key dimensions help judge stock or cut-length alternatives.

Stock, cut length, and end machining routes differ

Stock is usually fastest. Cut length needs length and packing confirmation. End machining also needs support model, bearing journal, lock thread, and coupling end details. State which dimensions must match and which can accept an alternative option.

Give boundaries for alternatives early

If the original model cannot ship on time, state whether the buyer accepts the same diameter and lead with another nut, different accuracy, bar stock first, or unmachined parts first. Alternatives still need installation and application risk review.

Urgent repair RFQ checklist

Urgent repair reason, machine downtime, target lead time, destination country, and shipping method.
Old part photos, diameter, lead, overall length, thread length, nut style, and axis.
Stock, cut length, end machining, support model, coupling, and packing request.
Acceptable alternative option, must-match dimensions, quantity, payment, and shipment photos.

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.
