How to Check Ball Screw Quotation Items Before Ordering

After receiving a ball screw quotation, buyers should compare more than unit price and confirm specification, machining, packing, and lead time boundaries.

Quotation itemWhat to confirmWhy it affects the order
Product scopeModel, diameter, lead, quantity, accuracyPrevents comparing different specifications.
Machining scopeEnd machining, support model, nut styleControls production work and fit risk.
Packing scopeRust prevention, labels, carton marks, wooden caseSeparates product cost from export protection.
Delivery scopeLead time start point, destination, shipment photosClarifies when production and shipping responsibility starts.

End machining and nut scope

If the quotation covers end machining, confirm the fixed side, the supported side, bearing journals, lock nut thread, keyway, coupling end and support unit model. Nut style, flange direction, preload or clearance should also be written into the quotation.

Packing and delivery boundaries

Packing should state rust prevention, carton, hard tube, wooden case, labels, carton marks and whether shipment photos are provided. Lead time should state whether it starts from order confirmation, payment received or drawing approval, so both sides read it the same way.

Confirm changes before payment

If quantity, length, accuracy, packing or shipping changed after the quotation, ask for an updated quotation. Using one confirmation checklist before payment reduces disputes during production and shipment. See how to confirm quotation validity and payment terms.

Confirmation checklist

  • Quotation version, model, quantity, diameter, lead, overall length, thread length, and accuracy.
  • End machining, support unit, coupling end, nut direction, preload, backlash, and inspection report.
  • Packing, labels, carton marks, rust prevention, shipment photos, and export document needs.
  • Lead time, payment terms, freight responsibility, changed items, and the person giving final approval.

FAQ

Can two quotations with the same model still differ? Yes. Quantity, accuracy, end machining, packing, lead time, and inspection report can all change the real scope. See how to confirm quote validity and payment terms.

When should I ask for a revised quotation? Ask for reconfirmation whenever quantity, drawing, packing, destination, or delivery target changes.
