This model of sewing machine has been developed while inheriting JUKI's advanced "dry" technology. JUKI is happy to launch the product which responds to customers' concern about oil stains on the fabric.
This advanced overlock machine is easier to use and promises superior cost effectiveness.

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.

The Juki MO-6800D Series responds to various kinds of sewing materials and processes, producing delicate and beautiful soft-to-the-touch seams while further reducing operating noise as well as increasing durability. This advanced overlock machine is easier to use and promises superior cost-effectiveness as well as the responsiveness from light- to heavy-weight materials with a lower applied tension.

The machine is provided with functions which contribute to easier operation.

The differential-feed micro-adjustment mechanism, external increasing of the differential feed ratio and the main feed dog height can all be adjustable on the front face of the sewing machine with a screwdriver. The machine is provided as standard with functions which enable easy and best-suited adjustments according to the material to be used.

The machine achieves beautifully finished seams of improved quality even when run at a high speed.

The machine is widely applicable to the sewing of light- to heavy-weight materials. Since the machine is provided with a needle thread take-up mechanism and a looper thread take-up lever, it ensures high-quality, well-tensed, and soft seams with a beautiful texture that flexibly correspond to the elasticity of the materials even when run at speeds as high as 7,000 sti/min. In addition, the machine has a wider and brighter needle entry and provides improved responsiveness to the materials, thereby helping the operator use the machine more easily. The optimally balanced design of the machine.
