Metal Bobbin Case for Home Sewing Machines with Latch

Bobbin housing for a home machine: when the bottom seam stops being uniform

In many home sewing machines, the bobbin does not enter directly into the machine, but into a metal bobbin housing that is pulled out from the front. The bobbin housing holds the bobbin on a central axis, and with the help of a spring and a small screw, it determines the tension of the bottom thread. Over the years, the bobbin housing can be scratched, the spring deformes, and the machine begins to make loops, tear thread, or sew loose seam. In many cases, replacing the bobbin housing returns the machine to sew properly.

This bobbin housing is made of metal with a silver finish, with a long locking handle. Pull the handle, and the bobbin housing comes out of the machine with the bobbin remaining locked inside and not falling off. Inside there is a round bracket with a center axis on which the bobbin sits, and on the side there is a tension spring with a directional screw.

What's in it

• Long locking handle: to take out and insert the bobbin housing, and the bobbin stays inside.

• Bobbin Bracket with Center Spindle: Holds the bobbin straight and allows it to rotate freely.

• Tension spring and directional screw: towards the tension direction of the bottom wire.

• Silver Finish Metal: Precise construction for smooth workmanship.

Common Uses

• Replacing a bobbin housing that has been scratched, cracked, or whose spring has deformed.

• Extra bobbin housing, with pre-directed tension for thick wire or tissue wire.

• Completing a lost part in an old machine or a machine that was bought second-hand.

Who is it suitable for

For seamstresses and seamstresses with a home sewing machine in which the reel housing is pulled out from the front, for repair shops and sewing machine technicians, and for sewing classes and schools that maintain several machines. In machines where the bobbin is placed on top, inside the machine, there is usually no removable reel housing, so it is not suitable for them.

Pro Tips

• Before buying: Compare the existing bobbin housing: shape, height, shape of the handle and spring. You can send us a photo on WhatsApp and we will help identify it.

• Inserting the bobbin: Place the bobbin on the spindle so that the wire comes out in the direction indicated in the instruction book, and pass it under the tension spring until it enters the slot.

• Simple tension test: Hold the bobbin housing by wire and shake slightly. It should drop slowly. Falls too fast: The voltage is weak. Does not move: The voltage is strong.

• Direction: Turn the screw a quarter of a turn at a time, and test on a piece of fabric.

Common mistakes

• Insert without hearing a lock: A bobbin housing that is not locked all the way causes noise, needles to break, and damage to the kidnapper.

• Using an inappropriate bobbin: A new bobbin housing will also not work well with a bobbin at the wrong height or material.

• Lubrication inside the bobbin housing: Oil inside the bobbin housing reaches the wire and felt. Grease only the dots that appear in the instruction book.

How is it different from the industrial bobbin case on site?

There is also a reel house for an industrial sewing machine on site. It is a reel house for household machines, with a long locking handle, and they do not replace each other. Next to it are metal bobbins and plastic bobbins for household machines in the category of bobbins and bobbin housings.
