Product features

An advanced full-featured machine that is ideally suited to the sewing of extra heavy-weight materials

The MO-6900J Series comes with a newly-developed feed mechanism that moves the top and bottom feeds separately.
With its improved feeding capacity and stronger cloth-biting force, the feed mechanism prevents uneven material feed when sewing extra heavy-weight materials.
- The machine incorporates mechanisms that are both durable and reliable, such as the needle bar mechanism, utilyzing the upper and lower bushings, a cartridge type oil filter and cooling fan.
- The machine is equipped as standard with a micro-lifter that helps reduce operator fatigue. The micro-lifter is designed to achieve optimum balance, not only reducing noise and vibration but also ensuring comfortable operation.
- Needle thread heat remover and needle cooler prevent stitching troubles during times of high-speed sewing, thereby contributing to upgraded seam quality.
- The machine comes standard with various adjusting mechanisms, such as a micro-adjusting mechanism, all of which can be easily adjusted to enable the machine to perform sewing under the best-suited conditions for any kind of material.
