Consew 339RB-4  

is a high-speed, double-needle lockstitch machine engineered for heavy-duty applications. Unlike standard machines, it features a Large Vertical Axis Hook and a Triple Feed (Compound Feed) system. This ensures that even the thickest leathers, canvases, and upholstery fabrics are fed through the machine with absolute precision, preventing material shifting or "creeping." 

Equipped with two needles, it produces two perfectly parallel rows of reinforced stitching in a single pass.  

  • Triple Feed (Compound Feed): Synchronized needle, feed dog, and walking foot action provides positive traction on heavy, slippery, or multi-layered materials. 
  • Large Vertical Axis Hooks: Features two large hooks that accommodate high-capacity bobbins, significantly reducing downtime when using thick industrial threads. 
  • Twin-Needle Precision: Delivers two perfectly parallel seams simultaneously—essential for structural reinforcement and decorative topstitching. 
  • Safety Clutch: An integrated safety mechanism automatically disengages the hooks to prevent damage in the event of a thread jam or needle strike. 
  • High Presser Foot Lift: 5/8" (16mm) clearance allows for the effortless insertion of thick, bulky assemblies. 
  • Adjustable Speed Servo Motor: The brushless motor allows for "stitch-by-stitch" precision on detailed corners while providing immense piercing power. 
  • Max Speed: 2,400 SPM (Stitches Per Minute) 
  • Stitch Length: Max 2-1/2 s.p.i. (10mm) 
  • Needle Gauge (Spacing): Standard 1/4" (6.4mm) — Other sizes from 1/8" to 1-1/2" available 
  • Clearance Under Foot: 5/16" (8mm) by hand; 5/8" (16mm) by foot 
  • Needle System: 135 x 17 
  • Bobbin Type: Large Metal (18034) 
  • Work Space: 10" (258mm) 
  • Stitch Type: 301 Lockstitch (Double Needle) 
  • Automotive & Marine: Seaming and topstitching seat covers, dashboards, boat interiors, and convertible tops. 
  • Furniture Upholstery: Specialized for leather sofas, armchairs, and heavy cushions. 
  • Luggage & Travelware: Manufacturing suitcases, golf bags, backpacks, and heavy canvas totes. 
  • Heavy Apparel: Constructing leather jackets, tactical gear, and protective workwear.

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.
