JUKI LU-2810NVA-70BBSZ Industrial Single Needle Direct-Drive Unison-Feed Digital Lockstitch Sewing System for Heavy Materials with Double-Capacity Hook (SC-952AD Control Box)

JUKI LU-2810NVA-70BBSZ — 1-Needle Semi-Dry, Direct-Drive Unison-Feed Digital Lockstitch Sewing System for Heavy Materials with Double-Capacity Hook, Automatic Thread Trimming & SC-952AD Control Box

The JUKI LU-2810NVA-70BBSZ is a heavy-material workstation designed to keep big upholstery and leather jobs moving smoothly shift after shift. Digital control of stitch conditions, multi-layer detection and one-touch changeover work alongside a direct-drive unison-feed head with a double-capacity hook and built-in thread trimmer. This combination means faster ramp-up on new styles, more stable quality across operators and a visibly higher standard of finish on key product lines.

What Sets the JUKI LU-2810NVA-70BBSZ Apart

• Color Touch Panel for Centralized Control
  The color operation panel shows key sewing conditions — thread tension, stitch length, presser-foot pressure, alternating vertical movement and more — on one screen. Operators and technicians see all settings at a glance and make corrections quickly at the head.
  
• USB and NFC Connectivity for Easy Data Management
  A standard USB port lets you back up and transfer sewing data and update software from a USB thumb drive, while the built-in NFC technology enables contactless 2-way data exchange with an Android device running JUKI Smart App. Together they speed up style changes, move settings from one head to another in a few steps, and keep machine status visible across the line.
  
  
• Multi-Functional Six-Key Hand Switch for Instant Changeover
  The six-key hand switch lets operators call up pre-set sewing conditions — stitch length, needle-thread tension, alternating lift, presser pressure and speed — without leaving the seam. Initially, keys 4–6 are assigned to automatic reverse feed, needle-entry alignment and thread clamping, so core actions sit directly under the thumb.
  
  
• Automatic Trimming and Double-Capacity Hook for Longer Runs
  A built-in thread trimmer cuts at the end of each seam, removing manual snipping, while the vertical-axis double-capacity hook carries roughly twice the bobbin yardage of a standard hook. Together they cut out scissor time and extend the interval between bobbin changes, lifting throughput on long seams and extended runs.
• Multi-Layer Detection Function
  When the seam reaches a joint or layered area, the multi-layer detection function can automatically switch stitch length, tension, presser pressure and alternating lift to the values defined for that section. Once thresholds are taught, step-ups are recognized consistently and joints stop being the weak link in the seam.
• Digital Control of Needle-Thread Tension and Presser Pressure
  Needle-thread tension and presser-foot pressure are set on the panel, stored with each program and reproduced automatically when the style is recalled. In automatic mode, the multi-layer sensor adjusts pressure as thickness changes; in manual mode, pressure control can be put on a hand key. This shortens setup, keeps topstitching stable and helps heavy stacks climb smoothly with less marking.
  
  
• Step-by-Step Sewing for Complex Continuous Seams
  For polygonal or multi-material seams, conditions can change step by step using stitch count, one-touch changeover and multi-layer detection as triggers. The machine walks the seam through each stage automatically, so straight runs, turns and overlaps all carry the same controlled, high-end finish.
  
  
• Jog Dial for Precise Needle Control
  The jog dial turns the main shaft to move the needle up and down without reaching for the handwheel and can be pushed for a 1/2-stitch correction. This gives fine control at corners, notches and other detail points on heavy assemblies.
  
  
• Semi-Dry Direct-Drive Head for Cleaner, Quieter Operation
  The advanced lubrication system, with minimized oil quantity at the hook, reduces the risk of oil stains on finished goods. A compact AC servomotor is built directly into the head, removing the belt and lowering vibration and noise at the workstation.
• Energy-Saving Backlight-Off and Sleep Functions
  The operation-panel backlight can switch off automatically after a preset time, and a sleep (automatic power-OFF) mode cuts power when the machine sits idle. Both functions help trim energy consumption and avoid unnecessary wear on the drive system.
• Standby Switch for Safer Maintenance
  Pressing the standby switch disables drive from the pedal, operation panel, six-key switch and jog dial, so the head cannot start unexpectedly. Threading, needle changes or gauge replacement can then be done by turning the pulley by hand, reducing risk during routine service.

Included Components

• SC-952AD Control Box 
  The reliable control box built for the direct-drive AC servomotor supports quick start-up and accurate stopping so the head responds promptly even on heavy-material runs. It also underpins the machine’s digital functions — from data storage to controlling speed and other program parameters.
  

How It Improves Your Workflow

• Higher Output per Station on Heavy Lines
  The direct-drive unison-feed head runs at up to 3,500 stitches/minute, with automatic thread trimming and a double-capacity hook reducing scissor work and bobbin changes. Operators spend more time sewing and less time on handling, lifting daily piece counts on heavy programs.

• More Stable Quality Across Operators and Shifts
  Stitch length, needle-thread tension, presser pressure, alternating lift and speed are stored as digital programs on the touch panel and recalled at a button press. Multi-layer detection can adapt the settings at step-ups and joints, keeping seam appearance and performance consistent regardless of who is at the machine.

• Faster Style Changes and Easier Standardization
  Article-specific settings can be saved, adjusted once and reused, with USB/NFC support helping move those programs between stations. One-touch changeover keys allow section-specific sewing sets within a single seam. 

• Less Rework and Fewer Issues on Critical Seams
  Unison feed, digital control of tension and presser pressure, and step-by-step sequencing work together to keep topstitching straight and balanced, particularly over heavy overlaps and transitions. Joints and corners stop being typical weak points, reducing repair work, rejects and downstream complaints.

• Cleaner, Quieter and Safer Workstation
  The semi-dry lubrication with minimized quantity of oil at the hook helps avoid staining, while the direct-drive motor, LED lighting, energy-saving modes and standby safety switch make the station quieter, more ergonomic and safer to maintain. Over time, that supports smoother supervision and a more sustainable working environment.
