Quick answer
A ball screw inspection report should not only say passed. It should match the actual order, model, quantity, drawing revision, key dimensions, nut movement, appearance, and photo records so buyers can review risk before receiving.
The inspection report should match the actual order
A ball screw inspection report should not only say passed. Buyers can ask the report to show order number, model, quantity, drawing revision, or sample requirement so receiving and after-sales records remain traceable.
List the key dimensions clearly
Common inspection items include overall length, thread length, end dimensions, bearing journals, lock threads, shoulder positions, nut movement, appearance, pre-packing condition, and tolerance range. Custom or end machined orders should pay special attention to end dimensions.
Photo records are easier to review than text only
For repair replacement, distributor stock, or machine assembly orders, request photo records of key dimensions, nut movement photos or short video, appearance photos, and pre-packing photos for review before arrival.
RFQ checklist

FAQ
**Does every order need an inspection report?** Standard stock can use agreed sampling or photo records; custom, end machined, and high-accuracy orders should confirm key dimensions by order.
