Before choosing a part
Start with these documented details. Read the requirements with each answer before choosing a needle, bobbin or foot.
Raise the needle and lock the controls. The ordinary foot releases with the holder’s black button; the replacement pin snaps into the holder notch as the lever is lowered. Unlock the controls and raise the lever afterward. Use the correct foot for the stitch and this machine, and follow the complete procedure. Specified optional feet instead use the included adapter and small screw. This procedure does not identify a standard shank or prove another foot fits.
Requirements and sources →X52800-150, 11.5 mm high. Use the supplied bobbin or the same type; another model’s bobbin may cause malfunction. Standard class, material, diameter and broader interchangeability are not confirmed.
Requirements and sources →Use home sewing machine needles, specified as HA × 130.
Requirements and sources →Not yet confirmed here: Manufacturer accessory group, Presser-foot shank type, Foot holder / mount, Foot interface / generation, Bobbin type / class, Bobbin material, Bobbin diameter, 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.
Lock the controls and follow the full lever sequence. Specified optional feet use the included adapter and small screw instead. Use the correct foot for the stitch and this machine; a standard shank or universal fit is not confirmed.
Documents and page references →Keep the manual’s literal HA × 130 designation. Equivalence to another needle designation or product has not been confirmed.
Documents and page references →Owners should not oil Aerial. Contact an authorized retailer for a difficult handwheel or unusual noise; do not oil the bobbin case.
Documents and page references →This is the documented maximum, not a recommended speed for every material, stitch or job.
Documents and page references →Keep X52800-150, the 11.5 mm height and the supplied-or-same-type restriction together. Height alone does not establish fit, a standard class, material or cross-brand substitutes.
Documents and page references →Lock the controls and cover the needle-plate hole first. Insert the needle fully, flat side back, and securely tighten the clamp before unlocking.
Documents and page references →Keep the embroidery and short-jump/thread-trimming recommendations separate from the general fabric-and-thread table. Follow the table for the actual fabric, thread and task.
Documents and page references →Switch off and unplug before cleaning. Do not oil the machine; follow the complete illustrated removal, alignment and reassembly instructions.

Read the model-specific requirements with each answer before choosing parts.
Use home sewing machine needles, specified as HA × 130.
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.
Use 75/11 for embroidery and ballpoint 75/11 for short-jump patterns when thread trimming is on; 90/14 is recommended when embroidering heavyweight fabrics or stabilizing products. General sewing choices remain conditioned by the adjacent table.
Use the included X52800-150 bobbin, which is 11.5 mm high.
Only the included bobbin or bobbins of the same type as X52800-150 are supported.
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.
Only use presser feet made for this machine.
Specifications apply to the named model and document edition. Read any setup, fabric or safety requirements with the answer.
The maximum sewing speed is 1050 stitches per minute.
Do not oil the machine as an owner; the manual says its manufacturing oil makes periodic oiling unnecessary.
Switch the machine off and unplug it, remove the needle, presser foot, holder, flat-bed attachment or embroidery unit, 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.
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.
This guide covers model-specific manual instructions for bobbins, needles, feet, cleaning and sewing speed. Keep the requirements with each answer. Standard shank, maximum stitch width, bobbin class or material, hook classification and broader substitutions are not confirmed here.
An unanswered question does not mean a part is incompatible. We have not confirmed enough information to recommend it.
Presser foot — Standardized shank class: Not established Full recorded limit & conditions →
Bobbin — Class system: Not established Full recorded limit & conditions →
Other names, regional versions, production history, further specifications and documents are not fully covered here. Their absence is not a “none exist” finding.
