Perfect fit for my 1970s Shanghai model

I was worried this wouldn't fit my old machine, but it installed perfectly. The tension is now smooth and consistent, just like when the machine was new.

Excellent value for money

Hard to find parts for these older Chinese brands. This kit provided everything needed to restore the tension mechanism without breaking the bank.

Sturdy construction

Feels very solid compared to the worn-out original part. The spring tension is adjustable and holds well even with thicker denim threads.

Works on Flying Man models

Successfully installed on my Flying Man JA1-1. It took about 20 minutes to swap out. One screw was slightly different, but I used the original one and it worked fine.

Saved my favorite heirloom machine

My grandmother's Peony sewing machine has been sitting idle for years due to tension issues. This universal tensioner fixed it immediately. Highly recommended for vintage restorations.

Good quality, instructions could be better

The part itself is excellent quality metal. However, the installation diagram was a bit vague. I had to watch a YouTube video to get it right. Works great now though.

5 FAQ

Q: Is this part suitable for heavy-duty leather sewing?

A: While the tensioner is sturdy, it is primarily designed for standard home sewing tasks including denim. For very heavy leather, we recommend checking your specific machine's maximum capacity.

Q: Will this fit a Shanghai SEwing Machine model JA1-2?

A: Yes, this universal tensioner is designed to be compatible with the Shanghai JA1-2 model as well as other variants listed in the description.

Q: Does the package include the tension dial knob?

A: No, this package includes the internal tensioner assembly, springs, and mounting screws. The external dial knob is not included as it varies by specific machine aesthetic.

Q: Can this be used on a Huanan model from the 1980s?

A: Yes, the design is universal for most Huanan vintage models produced from the 1960s through the 1980s. It replaces the standard factory tension unit.

Q: Do I need special tools to install this part?

A: No special tools are required. A standard small Phillips head screwdriver and a pair of tweezers for handling the small spring should suffice.
