Motor Belts for Singer Sewing Machines

Whether you’re restoring a vintage Singer 15 or just replacing a stretched-out belt on your 201, the motor belt is one of the most critical components in keeping your machine sewing smoothly. This collection includes every size and style you’ll need to get your motor-driven Singer machine up and running again.

Vintage-Compatible, Easy-to-Install Motor Belts

Singer machines were built in many styles—some with side-mounted motors, others retrofitted from treadle setups. That’s why we stock a wide range of motor belts to match specific pulley sizes, machine styles, and motor types.

You’ll find belts that work with:

Singer 15, 66, and 99 models
Singer Featherweight 221 & 222
Singer Model 201 and 127/128 (with motor retrofit)
Singer 237 and 239 Fashion mate
Singer 185K and 285K
And other vintage low-shank electrified models

What size do you need? Each product includes a belt size chart and compatibility list to help you choose the right fit.

Quality You Can Rely On

We offer both OEM-style and modern upgraded motor belts. All are tested for strength, longevity, and quiet operation. Whether you're doing simple maintenance or a complete restoration, you can count on our belts to perform under real-world sewing conditions.

FAQs About Singer Sewing Machine Motor Belts

How do I know what size belt I need?
Measure from the center of the motor pulley to the center of the handwheel. Wrap a string around that path to get the total length. Or use our belt size chart on each product page.

Can I use the same belt for a Singer 15 and a Singer 66?
Often yes—but check the length. While many use a 15" V-belt, motor position or pulley diameter might differ slightly. If you're unsure, contact us for help.

What belt fits a Singer Featherweight 221?
That model typically uses a 17 1/2"" V-style belt. You can find compatible belts in our Featherweight-compatible listings. View all Singer 221 parts →

Do you carry belts for Touch & Sew models like the 720 or 758?
Yes, we stock timing belts specifically for Touch & Sew machines with internal drive systems.

What if I’m converting a treadle machine to electric?
You'll need a compatible motor and belt. Our motor upgrade kits include belts that fit standard retrofit systems.

Can I use a stretch-fit belt?
Stretch-fit belts are great for ease of installation and tension. Just make sure you buy one specifically matched to your model’s dimensions.
