- Top and bottom feed mechanism
- Presser Foot lift max 15mm
- Speed control with a max of 2,000 SPM
- Throat Size: 10.25 inches
- Double bobbin capacity
Standard Features:
- Top and Bottom-feed: With its powerful top and bottom feed mechanism, the machine smoothy feeds a difficult-to-feed material or a multi-layered part of material without pitch errors, achieving consistent seam quality.
- Knee-lifter: Mechanism is built into the bed which facilitates raising the foot up to 15 mm and by hand 5.5mm
- Low Vibration and Low Noise: The machine head is designed to achieve optimum balance, thereby reducing vibration and noise. The machine affords the operator a comfortable working environment
- Large Sewing Area: The Juki DU-1181N features a large sewing area with a throat space of 261mm/10.28" from the needle to the machine's arm. This makes it easier to handle large pieces of fabric.
- Maximum stitch length: With its stitch length being as large as 9 mm, the machine is applicable to a broader range of sewing processes.
- Lubrication: The machine comes with a lubricating mechanism that uses a centralized oil wick. This substantially reduces the time and trouble required for oiling the machine. It is recommended to oil the hook area.
- High-speed performance Increases Productivity: The machine delivers increased productivity at sewing speeds as high as 2,000 stitches per minute.
- Servo Motor: It comes with a high-torque, direct-drive motor, which provides smooth, consistent stitching without the need for a clutch motor. This makes it more energy-efficient and quieter compared to older models. This motor is a quieter and hardly makes noise. It is also draws less electrical power making it more efficient. The motor is the Family S Servo 550 W 3/4 HP.
- Optional Digital Motor for Needle Positioner: When using a needle positioner, a digital motor is used over a servo motor because it offers precise control, instant response, and advanced integration with the machine’s electronics, allowing for accurate needle positioning at specific points. Digital motors provide smooth, efficient power with real-time adjustments for varying tasks, ensuring the needle stops exactly where needed without jerky movements. They are more responsive and capable of fine-tuning the needle’s position.The motor is the brushless Juki J7R 650 W 3/4 HP.
- Straight Stitch: The Juki DU-1181N is designed primarily for straight stitching, which makes it ideal for high-quality seam work on those heavier materials.
- The Reverse Stitching Feature on the Juki DU-1181N is truly impressive. This machine offers seamless, precise reverse stitching that follows the exact line of the forward stitch, ensuring a clean, professional finish every time. It’s easy to switch directions, making it perfect for reinforcing seams or locking stitches.
- Needle System: It uses a standard DP×17 needle system, making it easier to find replacements or upgrades depending on the material being sewn.
- Needle Sizes: At time of delivery the machine has a size 21. It can use from size 14-23
- Assembled with Servo Motor: Refer to our installation video below on what to expect when you receive your Juki 1181

Why Choose the Juki DNU-1181N?
The Juki DNU-1181N is an excellent choice for those seeking a reliable, high-quality industrial sewing machine for medium-weight materials. It features a top and bottom feed system that provides better fabric control than standard single-feed machines, making it ideal for sewing materials like vinyl, canvas, synthetics, and light leather.
With a powerful motor and a max stitch length of 9mm, it handles thicker threads and seams with ease, while the walking-style foot helps reduce fabric slippage and ensures smooth, even stitching.
With its durability, precision, and performance — and at a more accessible price than heavier-duty compound feed models — the Juki DNU-1181N is a smart choice for small shops, hobbyists, and businesses using working with a mix of materials that don’t require a full walking foot system.
What’s the Difference Between the Juki DNU-1541S and the Juki DNU-1181N?
Understanding how these two models compare is key to choosing the right machine for your specific needs. While the two models share some similarities in build quality and design elements, their feeding mechanisms set them apart, affecting the type of materials they suit and how reliably they feed those materials.
Juki DNU-1181N — Top & Bottom Feed (Scuff Feed System)
- System: Uses a top and bottom feed system, often referred to as a "scuff feed" — where the inner and outer presser feet alternate to move the fabric while the feed dogs push from below.
- Action: While this system is fine for medium-weight materials, it lacks the added grip of a needle feed, which can lead to shifting or uneven stitches on tougher projects.
- Ideal For: Light to medium-weight materials such as light canvas, vinyl, and synthetics.
- Limitations: Not recommended for dense or multilayer materials. It may struggle on heavy seams and isn't built for continuous high-torque use.
Juki DNU-1541S — True Walking Foot (Compound Feed / Triple Feed System)
- System: Features a compound feed, also known as a triple feed system, where the needle feed, inner presser foot feed, and bottom feed (feed dogs) all move in synchronized motion.
- Action: With this system, fabric is firmly gripped from both the top and bottom and pulled evenly through the machine. This significantly reduces slippage, shifting, or skipped stitches, especially when working on layered or heavy materials.
- Ideal For: Upholstery, leather goods, tarps, car seats, canvas bags, denim layers — anything that demands strength and consistency.
- Benefits: Delivers excellent stitch quality even over thick seams and layered fabrics. It’s built for long hours, tough materials, and jobs where failure is not an option.
Quick Comparison:
Feature |
Juki DNU-1181N (Scuff Feed) |
Juki 1541 (Triple Feed) |
| Feed Type | Top & Bottom Feed | Compound / Triple Feed |
| Needle Feed | No | Yes |
| Heavy Material Handling | Moderate | Excellent |
| Stitch Consistency | Can Vary | Superior |
| Fabric Shifting | Possible | Minimized |
| Ideal For | Vinyl, Light Canvas, Synthetics | Upholstery, Leather, Tarps |
Bottom Line:
For heavy-duty applications such as upholstery or thick materials, the Juki DNU-1541S — with its true walking foot — is the superior option. In contrast, the Juki DNU-1181N is a well-suited mid-tier machine for lighter applications, though it may not match the strength and precision of the Juki DNU-1541S when handling very tough or multilayer materials.
