JIN NA-11UT — Direct-Drive Top & Bottom Feed Walking-Foot Lockstitch Auto Thread Trimmer
Heavy-duty, quiet, and fast. Built for upholstery, leather, canvas, bags & more—with the control you need for professional results.
✔ Ready to sew heavy materials · ✔ Even feeding · ✔ Clean trims at the touch of a button
Direct-Drive Power
High-torque, energy-efficient motor mounted right on the shaft for strong needle penetration, low vibration, and precise speed control.
Top & Bottom Feed
Walking-foot style feed moves thick, sticky, or multi-layer materials evenly—no slipping or “creep” on long seams.
Automatic Thread Trimmer (UT)
Finish a seam and the machine trims your threads—speeding production, reducing cleanup, and improving finish quality.
Double-Capacity Hook
Fewer bobbin changes on long upholstery runs or bag panels means more time sewing and fewer interruptions.

FAQs
Is the NA-11UT good for leather?
Yes. The walking-foot feed and direct-drive torque provide smooth feeding and needle penetration through leather stacks and sticky vinyls.
What’s the difference between NA-11 and NA-11UT?
Functionally similar, but the UT version adds the automatic thread trimmer for faster workflow and cleaner finishes.
How fast can it sew?
Factory rating up to 2,000 spm. We recommend dialing in a comfortable working speed via the integrated panel for control on thick materials.
