Quick answer
A custom ball screw RFQ should describe function before price: drawing, model, stroke, end machining, nut type, accuracy, preload, quantity, packing, and inspection needs. This lets weimute judge whether the order is mainly manufacturing, machining, assembly, or export packing work, and then quote the right process instead of a vague unit price.
Buyer decision table
| Custom requirement | What to confirm | Common quotation risk | | --- | --- | --- | | End machining | Bearing seat size, thread, keyway, shoulder, tolerance | Missing dimensions delay production review. | | Nut selection | Flange shape, hole pattern, preload, lubrication | Wrong nut style can block assembly. | | Accuracy and backlash | C7/C5 target, preload request, inspection report | Over-specified accuracy increases cost and lead time. | | Export packing | Length, rust prevention, wooden case, hard tube | Long screws need anti-bending support. |
RFQ checklist
- Drawing: PDF plus editable file if available, with all end machining dimensions visible.
- Working conditions: machine type, load direction, speed, stroke, duty cycle, and environment.
- Product details: diameter, lead, overall length, nut type, support unit plan, and accuracy grade.
- Quality documents: inspection report, material certificate, photos, or video confirmation if required.
- Commercial details: quantity, target delivery date, destination, packing standard, and payment terms.

FAQ
**Can weimute quote without a complete drawing?** Yes for early budget checks, but production quotation needs end machining dimensions and nut confirmation.
**Should I ask for C5 accuracy by default?** No. If the machine does not require ground precision, C7 rolled ball screws may reduce cost and lead time.
