Product Overview

The JUKI LU-2210 series is a high-speed, 1-needle, unison-feed (walking foot) lockstitch machine. It is specifically designed for heavy-duty sewing applications, such as sewing car seats, leather, and other thick, heavy materials. It is renowned for its exceptional feeding efficiency, high sewing speed, and ability to produce beautiful, high-quality seams without puckering or material flopping .

This model is available in two main variations:

• LU-2210N-7: Equipped with a vertical-axis 1.6 fold-capacity hook.

• LU-2210W-7: Equipped with a vertical-axis double-capacity hook .

Key Features

1. Superior Feeding Performance

• Unison-feed Mechanism: The walking foot and feed dog work together to move the material, ensuring consistent feeding of even the most difficult, multi-layered, or slippery materials .

• Box-type Feed Locus: This new feed cam unit creates a "box-type" feed locus, preventing material flopping and ensuring beautifully finished seams .

2. Enhanced Operator Convenience

• Higher Presser Foot Lift: The machine features a pneumatic auto-lifter as standard, providing a maximum presser foot lift of 16mm. This high lift allows for easy handling and positioning of thick or bulky materials .

• Easily Adjustable Alternating Vertical Movement: The vertical stroke of the presser foot and walking foot can be easily and precisely adjusted using a large dial on top of the machine head. The sewing speed is also automatically optimized based on the set value .

• Instantaneous Change-over (DL Device): The alternating vertical movement amount can be instantly maximized (using a hand or knee switch) when sewing over hard-to-feed parts like multilayered seams, preventing stitch gathering .

3. High-Efficiency Operation

• High-Speed Sewing: Supports a maximum sewing speed of 3,500 stitches per minute (sti/min) , significantly boosting productivity .

• Large Capacity Hooks: The machine is equipped with either a 1.6-fold or double-capacity hook. This reduces the frequency of bobbin changes, leading to more efficient sewing work .
