JUKI LS-2342H Industrial Single Needle Cylinder-Bed Unison-Feed Direct Drive Lockstitch with Large Vertical-Axis Hook (Thick Thread Type)

JUKI LS-2342H — Cylinder-Bed, 1-Needle, Unison-Feed Semi-Dry, Direct-Drive Lockstitch with 1.6 Fold-Capacity Vertical-Axis Hook (Thick Thread Type)

Built for modern leather workshops and upholstery lines, the JUKI LS-2342H combines a semi-long arm with unison feed and a heavy-thread specification to keep three-dimensional pieces under control. A slim cylinder geometry that can handle articles down to roughly Ø40 mm, dual tension and a high-torque direct-drive motor work together to drive thick leather and layered synthetics smoothly through curves, gussets and step-ups. The result is a compact heavy-duty station that keeps demanding bag, case and furniture work moving steadily, while seams come out clean, consistent and visibly refined.

What Sets JUKI LS-2342H Apart

• High, Semi-Long Arm for Easier Handling
  Space under the arm is 347 × 127 mm, giving operators generous reach and vertical clearance around the needle. Bulky bag bodies, leather shells and upholstery pieces can be spread out, turned and guided with less bunching and less struggle against the machine.
  
  
• Cylinder Geometry for Tight Curves
  A slim throat plate is built for sharp curves and small tubular pieces, allowing sewing on articles with diameters down to roughly Ø40 mm. This is particularly useful on bag corners, leather cases and wallets where radius control is critical.
  
  
• Heavy-Thread Capability
  The machine is set up for thick thread (#20 to #0). This gives enough capacity for structural seams and decorative topstitching on heavy-weight materials without running the machine at its limit.
• Dual Tension for Balanced Stitching with Thick Thread
  Dual tension is designed for thick thread under higher tension and helps keep top and bottom stitch appearance more consistent, including when seams pass through layered sections.
• Multi-Functional 6-Key Switch for One-Touch Actions
  The 6-key switch on the head can be used for functions such as one-stitch correction, stitch-length changeover and needle-thread tension changeover; unused keys can be assigned other functions as needed. Operators get direct access to frequent actions without leaving the seam.
  
  

• High-Torque Direct-Drive Motor for Heavy Assemblies
  A built-in high-torque direct-drive motor is designed for heavy materials, giving the machine quick response and strong needle penetration even through multi-layered sections. This keeps feeding smooth and reduces stalls or missed stitches.
  

• Unison Feed for Stable Seams on Shaped Work
  A unison-feed system moves presser foot, walking foot and feed dog together so the material advances as one. This synchronized feeding keeps thick leather or layered synthetics from slipping on the cylinder, helping maintain even stitch pitch and clean alignment around curves, gussets and other 3D elements.
