Long-selling unison feed sewing machine with simple functions that are easy-to-use and exerts strength in sewing thick materials.

Product features

  • Optimum for sewing car seats, bags, and sofas

    Realizes stable stitch balancing thread tension and adjustable lower position with adoption of built-in synchronizer that improves maintainability and enhances functionality and operability.
    Adoption of Limiservo X G-series improves operability and sewability.

Basic performance

  • Stable thread cutting performance from thin to thick threads

    The meshing of the fixed female and the female linearly moving in parallel with the feed dog enables excellent cutting of thread from fine to thick threads (#8).

  • Reverse needle raising function (when using Limiservo X)

    For easier insertion and removal of thicker materials, a reverse needle raising function is available.This function reverses the needle back after thread trimming to ensure a lifting height of 16 mm for the presser.

  • Powerful & high-performance Limiservo X G-series

    Our unique control technology realizes strong penetration from the first stitch.
    We have also realized reductions in size and weight, and have significantly improved durability.
    ●Equipped with simple sequence function
    ●Reverse-rotation needle-up function facilitates setting up and taking out sewing materials.

  • Control panel XC-G500 (Option)

    By attaching the operation panel to the sewing machine, the operator can perform operations without crouching. Operability has been greatly improved compared to conventional functions, and storage volume of setting data has been doubled.

  • Variable speed pedal XC-CVS-3 (Option)

    Variable speed operation is possible for standing work. It is especially effective such as when sewing corner curves.
    ●Variable speed operation is possible according to how much the pedal is depressed.
    ●The pedal can be easily secured on the table leg side rail.
    ●External signal operation is possible by using the foot switch for thread trimming and presser foot operation.

  • Automatic foot lifter (Pneumatic) LE-FA (Option)

    By adopting the pneumatic type, a presser lifting operation that was conventionally performed with the operator’s knee can be performed with the pedal. This eliminates the need for the operator to raise a knee during sitting work, reducing the burden on the operator. This device must always be attached during stand-up work.
