Direct-drive, High-speed, 1-needle, Lockstitch Machine with Automatic Thread Trimmer (Electric Feed Length Control System )

JUKI’s first high-speed lockstitch machine with Electric Feed Length Control System (EFLeCS)
The direct-drive motor, control box, and color LCD touch panel of this sewing machine are now combined with the Electric Feed Length Control System (EFLeCS) – all integrated in the main body.

Product overview

Product features

  • Electric Feed Length Control System (EFLeCS)

    With the stepping motor used to control the feed mechanism, the feed pitch is adjusted with the color LCD touch panel control instead of the conventional pitch dial. The high-clarity display of the touch panel promises excellent visibility to enhance workability. The touch panel comes with every machine as standard, along with a lock function to prevent the operator from mistakenly changing the set values.

  • Design pattern

    Digitalized feed pitches dramatically widen the range of stitch designs.

  • Smart design integrating the control panel with the direct-drive motor and machine head

    Compared with the conventional V-belt driven sewing machine, this sewing machine is driven by a direct-drive motor that consumes about 25% less power. The control box is integrated with the machine head to facilitate machine setup, and now comes with a USB port for charging.

  • The length of thread remaining on the material at the end of sewing is 3.5mm

    The machine adopts a double-blade drive rotary thread-trimming mechanism. By trimming thread just under the needle, this thread-trimming system consistently leaves no more than 3.5 mm of remnant thread on the material at sewing completion.

  • Beautiful finished seams

  • Nipper device

    This device pulls the needle thread into the wrong side of the material at the beginning of sewing, thereby ensuring more beautifully-finished seams.

Basic performance

  • Oil Shielding System

    In order to prevent oil stains on sewing products, the sewing machine has adopted the “Oil Shielding System” which is integrated into the sewing machine bed. The needle bar is lubricated with a smaller quantity of oil as compared with the conventional model. In addition, oil which externally splashes is shielded by the frame oil recovery mechanism and automatic oil circulation mechanism. This structure contributes to the achievement of the maximum sewing speed of 5,000sti/min and also to increased productivity.

  • Elimination of oil stains on sewing products

    Oil is stored in the oil-shielded made of highly rigid aluminum die cast which is integrated into the machine head and provides increased cooling performance. The oil-shielded has increased sealing performance as compared with a plastic oil tank and effectively prevents oil leakage and tank breakage.

  • Stepping motor drive for the thread trimmer and auto-lifter

    The drive mechanism for the thread trimmer and presser lifter has been switched from solenoid drive to a single stepping motor. The new mechanism substantially reduces operating noise, 
    especially for the tread trimmer.


  • LED lighting which illuminates the needle entry area

    Since the LED lights cast their light exactly downward to illuminate the needle entry area from the right and left sides of the needle bar, sewing work can be carried out more easily as compared with the use of light from one direction. In addition, the illuminance of the LED lights can be adjusted in three steps and can be used as an auxiliary light for work.

  • Hand switches

    Two customizable hand switches are provided as standard. The assignable button functions include back-tack stitch, needle up/down stitch, one-stitch sewing, condensation stitch, etc.

  • Auto-lift and knee lifter

    Shared motor power with the thread trimmer now makes it possible to provide the auto-lifter as standard. A highly demanded knee-lifter is also provided as standard for further enhanced workability.
