Juki MO-6916R-FF6-50H 5 Thread Overlock Top Feed Extra High Lift INDUSTRIAL SEEWING MACHINE

Juki MO-6916R-FF6-50H – 2-Needle, 5-Thread Top Feed Overlock / Safety Stitch Machine

The Juki MO-6916R-FF6-50H is a high-speed industrial overlock engineered for medium- to heavy-weight fabrics, featuring an extra-high lift upper looper and a 4.8mm x 4.8mm needle gauge. It delivers smooth, precise seams while preventing fabric damage, even on challenging materials.

As part of the MO-6900R Series, this model uses a variable top and bottom feed system to prevent uneven feeding and distortion. It can easily handle mixed-fabric seams, ruffling, and piping while maintaining seam integrity.

The high-lift design increases material clearance, making it ideal for bulky seams and multi-layer work. The upper looper’s extra-high throw enhances stitch formation for thick materials while the micro-lifter feature improves handling responsiveness.

Key Features
