SA140 / F033N
Directly listed by Brother for XR9550/XR9550PRW.
The model-specific options page names this exact walking-foot identifier.
Evidence note C052 · United States
Does the Brother SA140 walking foot fit an XR9550?
Brother’s model page answers this more safely than a generic low-shank or stitch-width rule. The exact accessory listing decides.
Direct answer
Yes. Brother lists SA140 / F033N for the XR9550/XR9550PRW.
Brother’s XR9550/XR9550PRW Consumables & Options page lists SA140 / F033N as its walking foot for slippery fabrics and quilting layers. Brother’s XR9550 walking-foot FAQ also names SA140 / F033N among supported walking-foot accessories. That is direct model evidence; do not reject SA140 merely because a seller labels another foot 5 mm or calls SA140 7 mm.
Decision map
What the identifiers actually prove
Family resemblance is not compatibility evidence. Each row stops exactly where the cited source stops.
Verify first
A generic foot chosen only by “low shank” or width
Those labels are not a complete compatibility answer.
The fork position, needle-clamp lever, attachment geometry and usable stitch path still have to match.
Do not infer
SA140 rejected because it is called 7 mm
That shortcut conflicts with Brother’s exact model listing.
Model-specific manufacturer evidence is stronger than a family-width rule.
Before buying
Run these checks in order.
- 01
Confirm the machine label says XR9550 or XR9550PRW.
- 02
Use Brother identifier SA140 / F033N when shopping; do not rely only on a seller’s generic “low-shank” title.
- 03
Follow Brother’s walking-foot installation instructions: remove the presser foot holder, place the operating lever over the needle-clamp screw and tighten the holder screw securely.
- 04
Turn the handwheel through a full stitch slowly before powered sewing and stop if the needle, foot or lever interferes.
Primary evidence
Source links, not search snippets.
Evidence boundary
What this page does not prove
This note confirms Brother’s own XR9550 listing; it does not certify every third-party foot that copies the SA140 number or general appearance. Listings can contain mixed identifiers, so verify the physical product and return policy before buying.
