Juki LS-2342H Heavy Duty Single Needle Cylinder Bed Unison-Feed Lockstitch Industrial Sewing Machine Complete Unit with Table and Servo Motor

This heavy-duty cylinder-bed lockstitch machine is built for sewing three-dimensional and hard-to-handle items with greater control and consistency. Its unison-feed design and slim cylinder geometry help it manage sharp curves, small tubular pieces, and layered sections common in leather goods and upholstery work. The machine is also set up for thick thread, with specifications to support balanced stitching on demanding seams. A high-torque direct-drive system adds responsive power for heavier assemblies, helping maintain smooth feeding on tough materials.

MACHINE FEATURES:

  • High, Semi-Long Arm for Easier Handling: Space under the arm is
  • 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
  • Heavy-Thread Capability: The machine is set up for thick thread
  • 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.
  • Higher Stitch Quality on Heavy Work: Unison feed, dual needle tension and a high-torque direct-drive motor keep heavy leather and multi-layer synthetics feeding evenly, so stitch pitch and top/bottom balance stay stable with fewer defects and reworks.
  • Better Handling of 3D and Tubular Pieces: The cylinder bed and extended space under the arm make it easier to guide gussets, corners and narrow tubes, improving accuracy on complex bag bodies, cases and seat components.
  • More Stable Heavy-Thread Programs: This specific configuration is built for heavier thread, so structural and decorative seams run more predictably across shifts, with less tuning and troubleshooting from technicians.
  • Higher Sustainable Throughput per Station: Smoother feeding, stronger penetration and easier handling of bulky workpieces allow operators to hold speed and accuracy longer, raising the practical output of each workstation.
  • SC-922B Control Box: Controls the direct-drive motor with consistent response and good resistance to voltage fluctuation and electrical noise. The built-in power-saving function reduces consumption between jobs, which is noticeable when many machines sit on standby.
  • CP-18C Operation Panel: Compact control panel used together with the SC-922B to manage sewing programs on the machine. Speed and core settings are adjusted right where the operator works, which simplifies setup, training and daily supervision.
  • Cylinder Geometry for Tight Curves: The slim throat plate is designed for sharp curves and small tubular pieces and can handle articles down to roughly
  • Heavy-Thread Capability: Thread range of this specification is approx.
  • Dual Tension for Better Control with Thick Thread: Dual tension gives more precise control when sewing with thick thread under higher tension, helping maintain balanced top and bottom stitch appearance on heavy materials.
  • Multi-Functional 6-Key Switch for One-Touch Actions: The 6-key switch on the head can trigger actions such as one-stitch correction, stitch-length changeover or needle-thread tension changeover, with spare keys assignable as needed. Common functions sit at the thumb instead of on the panel.
  • High-Torque Direct-Drive Motor for Heavy Work: The built-in high-torque direct-drive motor gives quick response and strong penetration through multi-layer sections. Feeding stays smoother with fewer stalls and missed stitches on thick seams.
  • Unison Feed for Stable Seams on Shaped Items: With presser foot, walking foot and feed dog moving together, the unison-feed system advances material as one piece. Thick leather and layered synthetics are less likely to slip on the cylinder, helping keep stitch pitch and alignment steady around curves, gussets and 3D shapes.

Machine Warranty Protection

Besides any applicable warranties provided by the Original Manufacturer, Jacksew offers a standalone 90-day limited warranty on defects in materials and workmanship.

  • This warranty covers all the machine parts and labor but any shipping costs must be covered by the customer

  • Only applies under normal sewing conditions as prescribed for the machine

  • Consumable items are not covered (needles, bobbins, bobbin cases, springs, oil, and belts)

  • This warranty does not cover improper use or abuse under heavy use of machines

  • This warranty does not cover flood, fire, or other acts of nature

If there are any warranty issues that arise, we ask that you contact us immediately and let us know the details. In most cases, we can guide you with getting your machine in good sewing condition via phone, text or video chat.

If you need any parts that need to be replaced, we stock the majority of parts for immediate shipment. Some parts not in stock may have to be ordered from the manufacturer and may take 1 to 2 weeks for arrival.

If there is a critical issue that needs to be addressed and is out of scope of minor adjustments or repairs, we will ask you to send us the machine to our shop so we can have it repaired and have it back to good sewing condition. In most cases, we will only need the machine head shipped to us. Shipping charges - both inbound and outbound - are the responsibility of the customer.

Warranty issues do not arise frequently because of our commitment to assemble, test and verify each machine we ship out to our customers. We will never send you a machine directly from the manufacturer in boxes without knowing that the machine will be ready to operate upon arrival.

DISCLAIMER: DUE TO THE HEAVY WEIGHT AND SHIPPING METHODS USED FOR INDUSTRIAL MACHINES THEY MAY EXPERIENCE MARRING AND SCRATCHES DURING SHIPPING. THIS WILL NOT AFFECT THE OPERATION OF THE MACHINE.

ANY DAMAGE OCCURRING DURING SHIPPING MUST BE CLAIMED TO THE FREIGHT CARRIER IMMEDIATELY. UPON REQUEST, JACKSEW WILL PROVIDE ASSISTANCE IN FILING A CLAIM ON YOUR BEHALF DURING SUCH AN EVENT. PLEASE NOTIFY US WITHIN 5 BUSINESS DAYS.
