Bernina L 850 Air Threading Serger

Swiss engineers have created a masterpiece, which allows you to thread the machine even faster and more conveniently. Simply press the foot control and you're off!

The One-step BERNINA Air Threader

  • Simple threading with air
  • Now, you're ready to sew
  • Imaging threading that is actually fun

The looper threads are magically moved through the machine by air with one simple step on the foot control. Now both hands are free to guide the threads. The L 850 automatically sets the loopers in the correct position of the air threader – no turning the handwheel or searching for the right position.

Sew in comfort

  • Raise and lower presser foot easily
  • Both hands free to guide the fabric
  • Easy access to the needles thanks to presser foot that swings out

With the BERNINA Free Hand System (FHS) you can raise and lower the presser foot with your knee. In addition, the presser foot easily swings out for convenient access to the needles.

Total Stitch Control for perfect seams

  • Individually adjustable settings for Total Stitch Control
  • Perfect for working with various fabrics and threads in any combination
  • Fully adjustable differential feed

The L 850 offers several settings for Total Stitch Control - all individually adjustable. The best part? You can change all of these settings while sewing - including the thread tension, cutting width, stitch length and Micro Thread Control (mtc).

Extremely fast, precise & quiet

  • Sew up to 1,500 stitches per minute
  • Strong, consistent and precise at any speed
  • Extremely quiet

Not only can you sew quickly, but you can also sew stitch-by-stitch, making the flawless production of precise lines and curves a simple process. Plus, you will enjoy how extremely quite the BERNINA L 850 sews.

Quick threading

  • One-path, color-coded threading
  • Automatic Needle stop up function
  • Integrated Needle Threader

The integrated needle threader and automatic needle stop up function make threading the needles simple. You can easily change from an overlock seam to a rolled hem or flatlock seam in no time because the thread remains in the same threading path.

Grand sewing space

  • 5 5/8" right to the needle
  • Easy on/off extension table included
  • Convenient freearm

The space offered on the L 850 is generous by any definition. It has more room to the right of the needle and more work space height than any other BERNINA serger. Sew closed items with ease by simply sliding sleeves or cuffs over the convenient freearm.
