Which bobbin should I use?

Needles, bobbins, feet and other details for this model. Check the requirements before choosing parts.
Before choosing a part
Compatibility essentials
Start with these documented details. Read the requirements with each answer before choosing a needle, bobbin or foot.
- Foot attachment
Raise the needle and lock the controls before changing the foot. The ordinary foot releases with the holder’s black button; its pin snaps into the holder notch as the lever is lowered. Use the correct machine-specific foot for the stitch, in the correct direction, and follow the complete procedure. Specified optional feet use the included adapter and small screw instead of this ordinary sequence. This does not identify a standard shank or confirm another foot fits.
Requirements and sources →- Bobbin height
X52800-150, 11.5 mm high. Use the included bobbin or the same type. This does not establish a standardized class, material or cross-brand substitute.
Requirements and sources →- Needle system / designation
Use home sewing machine needles, specified as HA × 130.
Requirements and sources →- Needle sizes by fabric and use
Use 65/9–75/11 for lightweight fabrics, 75/11–90/14 for medium fabrics, 90/14–100/16 for heavyweight fabrics, and ballpoint 75/11–90/14 for stretch fabrics; never use thread weight 20 or lower.

Needle, bobbin & presser-foot details
Read the model-specific requirements with each answer before choosing parts.
Needle
System type
- No broader product equivalence is established.
Use home sewing machine needles, specified as HA × 130.
Needle insertion
- Cover the needle-plate hole first; an incompletely inserted or loose needle can break or damage the machine.
Raise the needle, lock all keys and buttons, loosen and remove the old needle, then insert the straight replacement fully to the stopper with its flat side facing back and securely tighten the clamp screw before unlocking the controls.
Fabric thread point conditions
- Follow the cited table and trial-sew; an improper fabric, thread and needle combination can bend or break the needle.
Use 65/9–75/11 for lightweight fabrics, 75/11–90/14 for medium fabrics, 90/14–100/16 for heavyweight fabrics, and ballpoint 75/11–90/14 for stretch fabrics; never use thread weight 20 or lower.
Bobbin
Exact compatible item
- The part code, height and same-type restriction are inseparable; no standardized class, material or cross-brand equivalence is established.
Use the included X52800-150 bobbin, which is 11.5 mm high.
Sources and pages
Substitutions
- A bobbin from another model can cause malfunction; no broader substitution is established.
Only the included bobbin or bobbins of the same type as X52800-150 are supported.
Sources and pages
Class system
Not yet verified- Not yet verified: The reviewed exact manual page does not name a standardized bobbin class.
Presser foot
Attachment mount mechanism
- The ordinary pin-and-notch sequence is not universal: the same manual names the included adapter and small screw for specified optional feet.; Use the correct foot for the selected stitch and install it in the correct direction before sewing.
Raise the needle, lock the controls, raise the foot lever, press the holder's black button to remove the foot, align the replacement foot pin with the holder notch and lower the lever until the pin snaps into the notch, then unlock the controls and raise the presser-foot lever.
Sources and pages
OEM compatibility boundary
- No standardized shank, universal fit, third-party fit or cross-brand compatibility is established.
Use presser feet made for this machine.
Sources and pages
Standardized shank class
Not yet verified- Not yet verified: The reviewed exact manual pages do not name a standardized or low shank class.
Specifications & documented facts
Specifications apply to the named model and document edition. Read any setup, fabric or safety requirements with the answer.
Performance & stitch capabilities
Maximum sewing speed

Sources and pages
Owner features
Lubrication
- Contact an authorized retailer for a difficult handwheel or unusual noise; do not oil the bobbin case.
Do not oil the machine as an owner; the manual says its manufacturing oil makes periodic oiling unnecessary.
Cleaning
- Keep the no-oil statement within the component scope stated by the exact manual and follow the illustrated reassembly alignment.
Switch the machine off and unplug it, remove the needle, presser foot, holder, flat-bed attachment, needle-plate cover and bobbin case, then brush or vacuum lint and dust from the race and surrounding area before reinstalling the case in the illustrated alignment.
