NOTE: Bernina USA is experiencing a shortage of sewing machines and parts due in part to last year’s interruption in the supply chain.  Please give us a call at 815-410-5068 to check on availability or to get your name on our waiting list.

Flawless finishes abound with this specialist on your team. The L 850 is a perfect complement to your sewing machine, since seams and hems of all sorts are its specialty. Our 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!

  • One-step BERNINA Air Threader
  • Extremely fast, precise and quiet
  • Convenient freearm
  • Total Stitch Control for perfect seams
  • Grand sewing space
  • Sew up to 1,500 stitches per minute
  • Easy on/off extension table included

  • 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.


  • 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).


  • 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.
