The BERNINA L 850 is the premium overlock machine in the L-Series, setting new standards in precision, speed, and ease of use. It features the unique one-step BERNINA Air Threading function, which allows threading of the looper threads in seconds – cleanly, quickly, and absolutely reliably. Thanks to its sturdy metal construction, powerful motor, and perfect differential feed, the L 850 delivers professional overlock seams on all types of fabric and effortlessly handles even demanding, elastic, or thick materials.
One-Step BERNINA Air Threading – Threading in seconds
With the innovative air threading system, the looper threads are automatically threaded at the touch of a button. The system is particularly powerful, works absolutely reliably even with fine or fluffy threads, and makes setting up the machine easier than ever before.
Perfect stitch quality on all materials
The BERNINA L 850 offers 2-, 3-, and 4-thread overlock stitches for professional finishing, rolled hems, flatlock seams, and elastic applications. Its finely tuned differential feed ensures perfect edges without waves or puckering – ideal for jersey, sweat, knits, sportswear, and more. The precise knife system delivers clean, even cutting edges.
Extremely quiet, fast, and powerful
With up to 1,500 stitches per minute, the L 850 operates very quickly and at the same time exceptionally quietly and stably. The strong motor effortlessly sews through multiple layers and provides full control at all times. The perfect synchronization of looper, needles, and knife ensures a precisely coordinated stitch pattern.
Large sewing area and maximum comfort
The L 850 features the largest threading and working area in its class. The high presser foot lift system, bright LED lighting, and generous slide-on table make it easier to sew large fabric pieces, curves, and voluminous materials. Thanks to the BERNINA Free-Hand System (FHS), the presser foot can be raised with a knee lifter – keeping both hands on the fabric.
User-friendly down to the last detail
With continuously adjustable presser foot pressure, easily accessible looper area, practical memory functions, color-coded thread path, and an integrated accessory box, operation is particularly convenient. The machine is of high-quality construction and designed for many years of reliable overlock work.
Ideal for clothing, fashion projects, activewear, and all stretchy fabrics
Whether T-shirts, leggings, hoodies, baby clothes, or professional edge finishes – the BERNINA L 850 delivers perfect, elastic seams and high-quality results at the highest level.
