Many times people have a hard time locating the correct belt for their sewing machine, when it’s actually quite easy. I’m going to walk you through the steps to locate the correct size and style for your machine
There are 4 main types of belts for all makes and models of sewing machines and sergers: ( from Sewing Parts)
Geared Belts V Belts
This type of belt is almost identical to the lug belt, except there are no ‘teeth’ on the inside of this belt. Lug Belts
This type of belt is by far the most common belt used for sewing machines and can be mistaken for a geared belt because most of them have ‘teeth’ on them that resemble a geared belt. The difference between this type of belt and a geared belt, is these ‘teeth’ don’t fit inside indentations on the motor pulley.
We recommend this belt over a lug belt or V belt because it stretches, so if your measurement was off, it will still work. They grip better and provide better traction with less slipping.
If your machine uses a geared belt, you have to use the exact belt made for your specific model. A geared belt has ‘teeth’ like the lug belt, but these ‘teeth’ fit inside grooves on the motor pulley. Hard to get these. Use this guide if you have your old sewing machine belt:
Remove the old belt from your machine.
Cut the belt in half.
Pull the belt to make a straight line, and measure against a ruler or tape measure to see the length of the belt. That’s the length that you need!
