JUKI MO-6914J-CH6-700 TOP FEED 4 THREAD OVERLOCK INDUSTRIAL SEEWING MACHINE

Juki MO-6914J-CH6-700 – 4-Thread Top Feed Overlock / Safety Stitch (Head Only)

The Juki MO-6914J-CH6-700 is a 2-needle, 4-thread overlock machine from the MO-6900J Series, purpose-built for extra heavy-weight materials such as denim, raised fabrics, mats, and carpets. Its variable top-feed system and coarse feed dog deliver a strong cloth-biting force and exceptional feeding stability, even with bulky or layered fabrics.

An extra high-lift upper looper and tractor presser foot allow for smooth handling of thick seams, while the independently adjustable top and bottom feed mechanisms prevent uneven feeding.

Engineered for durability, the MO-6914J-CH6-700 features upper and lower needle bar bushings, a shielded needle bar mechanism, cartridge-type oil filter, and cooling fan. Operator comfort is enhanced with a micro-lifter, reduced noise/vibration design, and built-in needle cooler and thread heat remover to maintain seam quality at high speeds.
