Product features

  • Oil stains on the sewing product are eliminated

    • Oil splashes are substantially reduced to eliminate oil stains on sewing products, thereby upgrading the finished quality.
    • The frequency of stain removal or re-sewing is reduced.
    • The machine achieves a practical maximum sewing speed of 7,000sti/min.
  • Cutting-edge dry technology for achieving a lubrication-free mechanism

    • The needle bar mechanism and upper looper mechanism have been re-designed to require no lubrication.
    • The most-advanced dry technologies, such as the special surface treatment applied to the major drive unit and the grease feeding method, contribute to higher durability. The machine does not splash oil after a long-period of use. The grease filler openings are newly provided for the sewing machine on two locations, i.e., one on the upper looper component and the other on the sewing machine frame, thereby improving maintainability.

  • Anti-material-slip type


    The sewing machine is fully equipped with adjusting devices and provisions to effectively prevent puckering of difficult-to-sew materials or new-generation materials. The operator is able to produce beautifully finished highquality seams without conducting difficult adjustments.

  • A variety of subclass machines is available
