Singer Model 500A Parts

Nicknamed the "Rocketeer" for its futuristic look, the Singer 500A was ahead of its time—and still sews like a dream decades later. With a solid internal gear system, slant needle design, and decorative stitch capability, the 500A is a favorite among vintage sewing machine collectors and daily users alike. But even the best machines need a little help staying in top shape. This collection includes genuine original singer model 500a parts and high-quality replacements specifically matched to the 500A, so you can keep your Rocketeer running strong.

Working on other vintage Singers too? Don’t miss our collection of Singer Model 401A parts, which shares several features with the 500A, or explore our wider Singer sewing machine parts collection. We also carry parts for specialty models like the Singer 66 and Singer 29K.

Why the 500A Needs Model-Specific Parts

While it shares some DNA with the Singer 500A, the 503A has unique features—such as an external spool pin system, built-in cams, and a slightly different motor and gear setup. Using parts from the wrong machine can result in timing issues, tension problems, or worse. That’s why this collection is specifically built around the Singer 500A. Every part here has either been pulled from a working Rocketeer or verified for 500A compatibility using original specifications.

What You’ll Find in This Collection

Our inventory is constantly changing based on what we’re able to salvage from donor machines, but most items are low-stock and hard to restock. Here’s what you’ll typically find:

• Bobbin cases and bobbin winders
• Gears and internal drive components
• Tension assemblies and thread control parts
• Presser feet and slant shank accessories
• Needle plates, feed dogs, and slide plates
• Power cords, foot pedals, and motor brackets
• Handwheels, balance wheels, and belt systems
• Rare cosmetic parts and decals

If you’re also restoring the cabinet your 500A came in, check out our treadle and cabinet parts collection for drawer pulls, hinges, and treadle belts.

Common 500A Repairs and Replacement Needs

We’ve helped hundreds of Rocketeer owners breathe new life into their machines. Some of the most common parts that need replacing include:

• Stripped or worn gears 
• Sluggish bobbin winders that no longer grip
• Cracked or brittle handwheels
• Damaged needle plates and feed dogs
• Missing or incorrect tension assemblies
• Slant shank feet swapped out for incompatible types

These machines were built to last, and with the right parts, there’s no reason they shouldn’t sew beautifully for another 60 years.

Quality and Compatibility You Can Count On

Every part in this collection is cleaned, tested, and inspected before it’s listed. If it’s not up to our standard, it doesn’t make the cut. If it’s a reproduction or compatible replacement, we’ve tested it against a real 500A to ensure performance.

Each listing includes:

• High-resolution photos
• Detailed condition notes
• Model-specific fitment guidance
• Clear labeling of original vs. compatible parts

If you’re not sure a part fits, just contact us. We respond quickly and can verify compatibility with a photo or model number.

Model Compatibility and Variants

The Singer 500A stands apart from the earlier 401A in a few subtle but important ways—primarily in its cosmetic design, spool pin setup, and internal wiring. That’s why we’ve built a dedicated collection for 500A owners. If you're working with a 401A or similar machine, you may still find overlapping parts in our 401A parts section.

Frequently Asked Questions

Do these parts fit the 500A Rocketeer only?
Most do. We label listings clearly—if a part also fits the 401A or another slant needle model, that’ll be in the description. If it says “500A-specific,” it’s been tested on that model.

How do I know if I have a 500A or 503A?
Check the model number plate on the front or underside of your machine. The 503A looks similar but lacks the built-in decorative stitches. If you’re unsure, send us a photo.

Are these parts original or new?
We stock both. Vintage originals are salvaged from real Singer 500A machines and cleaned before listing. Reproductions or compatible parts are clearly labeled and tested for fit.

What if I can’t find the part I need?
Contact us. We have unlisted inventory and parts in donor machines that aren’t posted yet. Let us know what you’re missing and we’ll check our stock.

Can I use 401A parts in my 500A?
Sometimes—but not always. Many presser feet and cams are interchangeable, but motor parts, bobbin winders, and cosmetic components can vary. Always check the listing or ask before ordering.
