Juki DNU-1541-7 Single Needle Unison Feed Lockstitch Machine with Double Capacity Hook
Pneumatic pressor foot lift requires air compressor and hose attachment, Air compressor not included with machine purchase
Includes Fully Assembled Table and Servo Motor
With its reliable feed and consistent seam quality, the single needle lockstitch sewing machine responds outstandingly to the sewing of heavy materials.
With its larger needlebar stroke, higher presser foot lift, and newly adopted double-tension mechanism, the Juki DNU-1541-7 single needle lockstitch sewing machine offers excellent sewing capabilities and responsiveness. The alternating vertical movements of the walking foot and presser foot are as large as 6.5mm. In addition, the ratio between alternating vertical movements of the walking foot and presser foot remains unchanged even when the material thickness changes. Thanks to this feature and the adoption of a new method of rectangular feed that prevents needle from fraying, the machine sews multi-layered parts of a material with consistent stitching pitch while preventing stitch gathering.
Optional Upgradeable Control Panel
Standard (CP18) panel can be upgraded for a small fee to the CP180 control panel.
Assembled Table & Servo Motor
This Package includes a Fully Assembled Table and a Servo Motor.
Table and Motor may differ from the image shown.
The machine delivers increased productivity at sewingspeeds as high as 3,000 Stitches per Minute.
Since the needle thread tension-release solenoid is fitted on the rear face of the machine head, the area around the needle entry and one-touch type reverse feed button is easily viewable. This substantially contributes to improved operability.
Consisting only of a moving knife and counter knife, the simple and well-balanced thread trimming mechanism is capable of cutting thick thread up to without fail.
Automatic Reverse Feed
With just a light press on the one-touch type reverse feed button, reverse feed stitching is actuated. Furthermore, if a suspended ruler is attached on the machine or a 3-dimensional sewing product is sewn, the button can be shifted upward to prevent interruption.

Clutch motors operate at a fixed speed, typically between 1725 - 3450 rpm, depending on the type of machine. Servo Motors on the other hand are speed adjustable. The two major advantages of the Servo Motor are that you can control the speed of the motor and that the motor is completely silent when the pedal is not engaged.
Some other advantages of the Servo Motor include:
- They consume up to 90% less energy than clutch motors
- 1/3 lighter than clutch motors
- Reverse motor rotation with the flick of a switch
- Nothing to wear or adjust
- Adjusted speed remains the same no matter how hard the pedal is pressed
Most of our customers find that the single needle lockstitch sewing machine is much easier to control with a Servo motor because of the speed control. This is especially helpful for beginner sewers but also for projects that simply don't require high speed stitching.
