JUKI LG-158#U Industrial Double Needle Unison-Feed Long-Arm Lockstitch for Heavy Materials with Double-Capacity Hook

JUKI LG-158#U — 2-Needle Unison-Feed Long-Arm Lockstitch for Heavy Materials with Double-Capacity Hook

Engineered for long, strength-critical seams on oversized extra-heavy work, the JUKI LG-158#U pairs a 2-needle long-arm layout with unison-feed to bring disciplined precision to a production line. Generous 750 mm clearance under the arm, up to 21.5 mm presser-foot lift, a vertical-axis double-capacity hook for heavy thread and up to 10 mm stitch length are matched with built-in hook protection, delivering a calm, controlled sewing experience and a consistently refined seams.

What Sets LG-158#U Apart

• Long Arm for Large Heavy Panels
  A 750 mm distance from needle to machine arm and a 1,088×230 mm bed let operators spread out bulky workpieces, so long seams can be sewn with fewer stops and less wrestling with the material.
  
• Central Handwheel and On-Arm Bobbin Winder for Easier Handling
  With the handwheel positioned near the middle of the arm and the bobbin winder mounted on the front face, operators can control needle position and wind bobbins while large panels lie spread over the bed, keeping adjustments close at hand.
• Unison Feed Built for Extremely Heavy Materials
  Presser foot, walking foot and feed dog move in sync, keeping thick layers advancing evenly. This is crucial on multi-layer canvas, vinyl or coated fabrics where any slippage over long distances will show.
  
  
• Vertical-Axis Double-Capacity Hook for Heavy Thread
  The large hook sized for heavier thread counts (#20–#5 / B69–B138) allows operators to run strong load-bearing seams with fewer bobbin changes.
  
  
• High Presser Foot Lift for Thick Stacks
  A pedal-lifted presser foot height of up to 21.5 mm makes loading and unloading extra-thick assemblies practical, reducing struggle at the start and end of heavy seams.
• Hook Safety Device for Reduced Downtime
  A built-in safety mechanism disengages when thread gets caught in the hook, helping protect key parts; once cleared, the machine is returned to operation with a simple reset button.
  

• Adjustable Alternating Vertical Movement for Stacked Assemblies
  An alternating lift adjustment range of 6–19 mm lets you set how high the walking foot steps over the material. Feed system climbs over joints and overlaps smoothly, improving seam consistency and reducing skipped stitches on heavy transitions.

• Wide Range of Needle Gauge Variants
  At purchase, the machine can be configured with one of 11 needle-gauge options from 6.4 mm to 63.5 mm, with 19.1 mm set as the standard. This allows seam spacing to be set precisely for the requirements of a given production line.
  
  

How It Improves Your Workflow

• Higher Throughput on Large Items
  Long-arm 750 mm clearance, the 1,088×230 mm bed and a double-capacity hook reduce re-positioning and bobbin changes on extended seams, helping each station process more items within the same shift time.

• More Consistent Seam Quality on Heavy Goods
  Unison feed keeps multi-layer canvas, vinyl and coated fabrics moving in step, so long seams stay straighter and stitch density remains more uniform across the full run.

• Simpler Handling of Bulky Assemblies
  The 21.5 mm foot lift, central handwheel and on-arm bobbin winder make it easier to position thick stacks and manage adjustments while panels lie flat on the bed, streamlining day-to-day operation.

• More Uptime with Safeguarded Hook
  The hook safety device helps prevent damage when a jam occurs and allows quick reset once cleared, so the head spends more time available for production and less time waiting on repairs.
