Before choosing a part
Start with these documented details. Read the requirements with each answer before choosing a needle, bobbin or foot.
Not yet confirmed here: Manufacturer accessory group, Presser-foot shank type, Foot attachment, Foot holder / mount, Foot interface / generation, Bobbin type / class, Bobbin material, Bobbin diameter, Bobbin height, Hook type, Maximum stitch / zigzag width, Feed system, Bobbin loading direction. What is still to confirm →
Other names, regional versions and related models have not been confirmed here. A shared manual, product line or accessory group does not identify the machine's family.
Only part code X52800-150, shown on PDF page 22 (printed page 20). The manual names no bobbin class or other bobbin and warns that bobbins from other models won’t work correctly, so no substitute is confirmed here.
Documents and page references →The manual prints the generic category “home sewing machine needles” and no needle system code, so no system is confirmed here. Sizes are matched to fabric on PDF page 38 (printed page 36).
Documents and page references →Raise the needle and turn the machine off first. Use “Replacing the presser foot” on PDF pages 41–42 (printed pages 39–40). The manual states no shank type and restricts the machine to feet designed for it, so other feet are not confirmed.
Documents and page references →These are the straight stitch’s own ranges in the stitch settings table on PDF page 130 (printed page 128). Other stitches have their own ranges, and the manual states no single maximum width for the machine.
Documents and page references →Turn the machine off and unplug it first. Use “Cleaning the race” on PDF pages 140–141 (printed pages 138–139), then check that the bobbin case’s projection lines up with the spring. Don’t oil the bobbin case; the manual prints no owner oiling schedule.
Documents and page references →Work through the causes and remedies in the troubleshooting table on PDF page 142 (printed page 140). Its remedies and page references are not restated here.
Documents and page references →The code XC3153-151 is as printed on PDF page 141 (printed page 139), ordered from an authorized service center. No other bobbin case is named, so no other fit is implied.
Documents and page references →The manual names only twin needle X59296-151, so no other twin needle is confirmed. Thread it by hand: the needle threader can’t be used with a twin needle (PDF page 33, printed page 31).
Documents and page references →Codes are printed literally from the accessory list on PDF page 10 (printed page 8). The manual sends you to a Baby Lock retailer for the full optional list; no retailer fit is claimed here.

Read the model-specific requirements with each answer before choosing parts.
Home sewing machine needles only (PDF 37 / printed 35). Sizes run from 65/9 for thin fabrics to 100/16 for thick fabrics and top-stitching. Use a ball point needle (golden colored, 75/11-90/14) for stretch fabrics, and 90/14-100/16 with transparent nylon thread. A 75/11 needle is installed when you buy the machine (PDF 38 / printed 36).
No. The manual says to use only twin needle X59296-151 (one is included). Thread the needle by hand, because the needle threader can't be used with a twin needle (PDF 33 / printed 31; PDF 10 / printed 8).
Only the Baby Lock bobbin with part code X52800-150. The manual shows it at 11.5 mm (7/16 inch) actual size next to an "other model" bobbin, and it warns that bobbins from other models won't work correctly (PDF 22 / printed 20). Four come in the box (PDF 10 / printed 8).
Order part code XC3153-151 from an authorized service center. The manual says never to use a scratched bobbin case (PDF 141 / printed 139).
Raise the needle and turn the machine off first. Then follow "Replacing the presser foot" (PDF 41-42 / printed 39-40); the black button at the back of the holder releases the foot. Use only feet designed for this machine. The shank type isn't stated.
Thirteen feet come with it, including the walking foot BLG-WI, quilting foot FA2, stitch guide foot "P" FA6, adjustable zipper/piping foot FA9, non stick foot FA8 and open toe foot FA7. The five optional items are side cutter FA10, quilting guide FA11, extension table BLR-ET, 1/4 inch quilting foot FA1, and 1/4 inch quilting foot with guide ESG-QGF (PDF 10 / printed 8).
Specifications apply to the named model and document edition. Read any setup, fabric or safety requirements with the answer.
Turn the machine off and unplug it first. Then follow "Cleaning the race" (PDF 140-141 / printed 138-139). Don't oil the bobbin case. When you refit it, align the case's projection with the spring.
For straight stitch 01, the stitch settings table gives a manual width of 0.0-7.0 mm (0-1/4 inch) and a length of 0.2-5.0 mm. Other stitches have their own ranges in the same table (PDF 130 / printed 128).
The table lists 12 causes: an incorrectly installed needle, a loose clamp screw, a bent or blunt needle, the wrong fabric, thread and needle combination, the wrong foot for the stitch, tight upper tension, pulling the fabric, an incorrectly installed spool, a scratched or burred needle plate, presser foot or bobbin case, and a bobbin not made for this machine. Each has its remedy, with a page reference where the table gives one (PDF 142 / printed 140).
Use the full source procedure and its safety precautions. A short referenced answer is not a substitute for service documentation or qualified electrical/mechanical repair.
Service-manual availability and service-only procedures remain unestablished unless separately cataloged and reviewed.
Answers use this model’s own instruction manual with its stated safety conditions. Where the manual contradicts itself or gives no value, no answer is given. No hands-on testing or replacement-part fit is claimed.
An unanswered question does not mean a part is incompatible. We have not confirmed enough information to recommend it.
Other names, regional versions, production history, further specifications and documents are not fully covered here. Their absence is not a “none exist” finding.
