How to Send a Repeat Ball Screw Order RFQ List

Repeat order does not always mean no change

A repeat ball screw order should start with previous order number, previous model list, quantity, drawing revision, and shipment record. Even for repeat purchasing, material, accuracy, packing, and lead time plan should be reconfirmed.

List models line by line

If the repeat order includes multiple models, list model, diameter and lead, length, nut, quantity, and end machining line by line. Writing same as previous order may miss changed models or quantities.

Labels and packing may have changed

For distributor repeat orders, labels, carton marks, neutral packing, rust prevention, and shipment photos may change with customers or markets. The repeat RFQ should state whether this order uses the previous packing rule.

Give the lead time plan early

Repeat orders often relate to stock replenishment. State lead time plan, target arrival time, split shipment need, monthly quantity, and later replenishment rhythm so the supplier can arrange stock and machining.

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.
