JUKI MO-6843S  

is an ultra-high-speed industrial serger designed for maximum versatility in garment manufacturing. As a 6-thread safety stitch machine, it allows you to perform a wide range of overseaming and overedging operations on light to medium-weight fabrics. With a top speed of 7,000 SPM, advanced needle bar cooling, and Juki’s "S" type low-tension technology, it produces beautiful, flexible seams even at extreme speeds. 

The main advantage of the 6-thread model is future-proofing. Instead of buying separate machines for 4-thread knits and 5-thread wovens, the MO-6843S handles both. It is the perfect choice for contract sewing shops and designers who work with a variety of materials and need one machine that does it all.

  • Ultimate Versatility: 6-thread configuration allows the machine to be used as a 3-thread, 4-thread, or 5-thread safety stitcher, adapting to any production requirement. 
  • Ultra-High-Speed Output: Capable of reaching up to 7,000 SPM, making it one of the fastest and most efficient sergers available. 
  • Advanced Lubrication System: Features a forced-circulation oil pump and a specialized needle bar cooling system to prevent thread breakage and overheating during long runs. 
  • Low-Tension Sewing: The MO-6800S series is engineered for "soft-touch" seams, ensuring that elastic and delicate fabrics retain their flexibility. 
  • Micro-Adjustment Differential Feed: External lever allows for precise control of fabric feeding to prevent puckering or waving on stretch materials. 
  • Energy-Efficient Servo Motor: Includes a 110V digital Servo motor that provides silent operation and instant start/stop response. 
  • Stitch Type: 3-Needle, 6-Thread Safety Stitch (Type 514/516 base) 
  • Max Sewing Speed: 7,000 Stitches Per Minute (SPM) 
  • Overedging Width: 4.0 mm / 4.8 mm 
  • Safety Stitch Gauge: 3.2 mm / 4.8 mm 
  • Stitch Length: 0.6 mm to 3.8 mm 
  • Differential Feed Ratio: Gathering 1:2.0 / Stretching 1:0.7 
  • Needle System: DC x 27 (Standard) 
  • Presser Foot Lift: 7.0 mm 
  • Lubrication: Fully Automatic 
  • General Garment Assembly: Ideal for side-seaming on t-shirts, polo shirts, and casual wear. 
  • Intimate Apparel: Soft-seam construction for underwear, lingerie, and foundation garments. 
  • Sportswear: High-strength, flexible safety stitching for leggings, jerseys, and activewear. 
  • Woven & Knit Goods: Versatile enough for both light woven dresses and medium-weight knit sweaters.

JUKI DDL-8700 FAQs

What kind of needles do you use in the DDL-8700?

The needles with your JUKI are the Organ DBx1, available on our website. This machine uses size 16×257, size 8 through 20 or 16×97. The 8700 can also use standard needles, sizes 9 through 21, universal or fabric-specific needles such as knit.

Where does the machine oil go?

A pan directly underneath the machine supplies oil to the machine with a cotton wick. Lift the machine up and over to access the oil tank while on the table. You must keep the machine’s oil level consistently at the «high» mark, either by adding more oil or draining it and refilling it as needed. If the oil pump can’t get the oil into the machine, it can cause serious problems later.

What kind of oil does this machine require?

You need a specific type, like motor oil in your car, to keep this machine running. The DDL-8700 requires JUKI New Defrix Oil No.1, equivalent to ISO VG7.

What size table can I get with this machine?

Our table has legs and is 22"w x 47"l. It includes a knee and foot pedals and a left-hand drawer for accessories.

Does the DDL 8700 make buttonholes?

No. The 8700 only does straight stitching, with a horizontal bar on the right side for a reverse stitch.
