Juki MF-7523  

is a flagship industrial coverstitch machine engineered for professional garment finishing and elastic seaming. As part of Juki’s high-performance interlock series, it delivers exceptional stitch quality on a vast range of knit and stretch fabrics. Whether you are performing basic hemming or complex decorative topstitching, the MF-7523 ensures consistent thread tension and prevents material damage, making it the industry standard for high-end activewear and apparel manufacturing. 

  • 3-Needle, 5-Thread Configuration: Provides maximum seam strength and elasticity. Can be used as a 2-needle or 3-needle machine with or without the top decorative spreader thread. 
  • Micro-Lifter Mechanism: Allows the presser foot to be adjusted to a minute height, preventing fabric slippage or damage when sewing delicate or high-stretch materials. 
  • Differential Feed Adjustment: Features a specialized lever for fine-tuning the feed ratio, ensuring flat, wave-free seams on jersey, spandex, and ribbed knits. 
  • Adjustable Longitudinal Needle Position: The needle bar stroke can be adjusted to minimize needle heat and prevent "skipped stitches" during high-speed production. 
  • Quiet-Run Servo Motor: The included 110V electronic servo motor provides silent operation, significant energy savings, and total speed control for technical sewing. 
  • Improved Oil-Shielding: Features an advanced oil-blocking mechanism around the needle bar and looper area to prevent oil spots on finished garments. 
  • Easy Stitch Length Dial: A simple push-button and dial system allows for rapid adjustment of stitch length to suit different fabric weights. 
  • Stitch Type: 3-Needle, 5-Thread Coverstitch (Interlock) 
  • Max. Sewing Speed: 6,500 Stitches per Minute (SPM) 
  • Standard Needle Gauge: 5.6mm (Other sizes available) 
  • Stitch Length: 1.2mm – 3.6mm (Adjustable) 
  • Differential Feed Ratio: 1:0.7 – 1:2.0 
  • Presser Foot Lift: 5mm (with Top Spreader) / 8mm (without) 
  • Needle System: UY128GAS (#9 to #14) 
  • Motor Type: 550W High-Torque Servo Motor (110V) 
  • Lubrication: Fully Automatic (Force-feed system) 

The MF-7523 is the primary choice for professional knit garment construction: 

  • Hemming: Producing flexible, durable hems on T-shirts, polo shirts, and casual wear. 
  • Activewear: Decorative and structural coverstitching for yoga leggings, cycling jerseys, and swimwear.

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.
