Quick answer

End machining and BK/BF support unit selection should be quoted together. The ball screw shaft ends must match the fixed-side and supported-side bearing seats, lock nut, thread, shoulder, and overall assembly length. weimute can review the support unit plan before manufacturing so the machined screw fits the buyer's assembly.

Buyer decision table

| Assembly point | What to confirm | Risk if skipped | | --- | --- | --- | | Fixed side BK | Bearing seat diameter, shoulder, thread, lock nut | Screw may not clamp correctly. | | Supported side BF | Support diameter and length | End may not fit the support unit. | | Overall length | End machining plus thread length | Stroke or mounting position may shift. | | Nut orientation | Flange direction and lubrication access | Assembly may conflict with the machine layout. |

RFQ checklist

  • Send the BK/BF model or support unit drawing if already selected.
  • Confirm screw diameter, lead, total length, thread length, and nut type.
  • Provide both fixed-side and supported-side end machining dimensions.
  • Mark bearing seat tolerance, thread specification, keyway, and lock nut requirements.
  • Include quantity, application, destination, packing, and inspection report needs.

Send us the support unit plan

Send weimute your BK/BF support unit model and end machining drawing together. Our manufacturing and sales team will check whether the drawing matches the support units before quoting production.

FAQ

**Can I choose BK/BF after ordering the screw?** It is safer to confirm support units before machining, because shaft-end dimensions depend on them.

**Does weimute need the whole machine drawing?** Usually no. The end machining drawing, support unit model, nut orientation, and total length are enough for quotation review.

Next step

Turn this guide into an RFQ

When the specification direction is clear, send the details below together with quantity, lead time, and packing requirements.

Include these details

  • Support-unit model, end drawing, or old-part end photos.
  • Bearing journal, shoulder, lock thread, keyway, and coupling-end dimensions.
  • Overall length, thread length, quantity, inspection, and packing requirements.
