JUKI LU-2828NVA-7NBBSZ Industrial Single Needle Digital-Control Direct-Drive Unison-Feed Lockstitch for Heavy-Material Production with Large-Capacity Hook & SC-952AD Control Box

JUKI LU-2828NVA-7NBBSZ — Digital-Control 1-Needle Semi-Dry, Direct-Drive Unison-Feed Lockstitch for Heavy-Material Production with Large-Capacity Hook & SC-952AD Control Box

The JUKI LU-2828NVA-7NBBSZ is built for manufacturers who need both muscle and intelligence. Operating at a maximum speed of 3,500 stitches per minute, it pairs a robust unison-feed mechanism with digital precision, Internet of Things (IoT) connectivity, and automatic thread trimming system. Designed for leather, canvas, and multi-layer upholstery, it delivers quick setup and consistent seam quality shift after shift.

What Sets JUKI LU-2828NVA-7NBBSZ Apart

• Unified Digital Operation Panel
  All key settings — stitch length, presser pressure, alternate lift, thread tension, and speed — appear on a single screen. Saved presets eliminate manual readjustments between materials or operators.
  
  
• Internet of Things Connectivity and Smart Data Management
  Machine settings can be transferred via USB or contactless two-way data transmission (NFC) through the JUKI Smart APP. Operators can edit, store, and copy parameters across workstations — keeping production consistent and reducing setup time.
  
  
• Auto Thread Trimming (5 mm Remaining Length)
  A precision roll-in mechanism trims the needle thread close to the final stitch. No loose ends, no manual snipping, and perfectly clean finishes ready for assembly or packaging.
  
  
• Needle-Thread Clamping Device
  Automatically pulls the needle thread to the underside of the material at start-up, preventing tangles and guaranteeing a neat, professional seam appearance.
  
  
• Multi-Layer Detection
  Automatically identifies material thickness and optimizes stitch length, tension, and lift to maintain perfect feeding through stacked or padded assemblies.
• Active Thread Tension System
  Electronically adjusts thread tension in real time, automatically compensating for different materials or multi-layer sections to maintain perfect seam balance.
  
  
• Active Presser-Foot Pressure Control
  Sensors adjust presser pressure dynamically as material thickness changes, ensuring smooth feeding through layered or padded fabrics without flattening or distortion.
  
• 2.7-Fold Capacity Hook
  Large vertical-axis hook keeps operations running longer between bobbin changes, boosting efficiency on long panels and upholstery seams.
• Direct-Drive Motor with Jog Dial Control
  The built-in motor delivers powerful torque. A jog dial enables precise needle positioning or half-stitch corrections without touching the handwheel.
  
  
• Multi-Functional 6-Key Switch
  Six easy-reach buttons on the machine arm let operators control core actions — like reverse feed, alternating lift, or stitch-length change — without stopping sewing. 
  
  
• Semi-Dry Head
  A sealed oil system keeps internal parts protected and the sewing area spotless — no staining, minimal maintenance, and maximum reliability.
• Energy-Saving Function
  Automatic backlight-off and sleep functions cut unnecessary power use during idle periods, reducing energy costs and extending component life.
  

How JUKI LU-2828NVA-7NBBSZ Improves Your Workflow

• Digital Consistency Across Every Shift
  Store and recall exact stitch parameters for any product. Digital data transfer keeps every machine operating with consistent stored settings, maintaining quality across operators and shifts. 

• Effortless Handling of Heavy Materials
  The unison-feed mechanism, active lift control, and digital pressure adjustment keep thick or multi-layer fabrics feeding smoothly, avoiding slippage, puckering, and rework.

• Cleaner Finishes, Less Post-Work
  Short-thread trimming delivers neat, ready-to-pack seams. No scissors, no fraying, no wasted minutes at the end of the line.

Included in the Package

• SC-952AD Control Box 
  An advanced digital drive unit that powers and coordinates all key machine functions — from motor control to needle positioning and energy management. It ensures smooth acceleration, stable speed under load, and precise stop accuracy, even during heavy-material operation.
