The SW-4400-L18 is a Speedway lockstitch machine for upholstery.

The SPEEDWAY SW-4400-L18 is an industrial single-needle long-arm heavy-duty triple feed walking foot machine built for oversized, multi-layer projects that demand extended clearance and serious power. With an 18" arm, 6.5" height clearance, 900W belt-driven servo motor, and dual-tension mechanism for thick threads, it handles leather, canvas, upholstery, marine interiors, and industrial straps at up to 2,500 SPM — delivered fully assembled with table and stand.

What's Included

  • SPEEDWAY SW-4400-L18 long-arm walking foot machine (ships assembled)
  • Industrial table with wheels and stand
  • 900W high-torque servo motor
  • Standard walking foot presser foot set
  • Needle set (DPx17) and bobbins
  • Oil can and maintenance tools

Key Features

  • 18" long arm + 6.5" height clearance — extended workspace for oversized upholstery panels, boat covers, automotive interiors, and large multi-layer assemblies
  • Unison feed (walking foot) system — synchronized top and bottom feeding with rectangular feed mechanism prevents slipping on leather, vinyl, and heavy multi-layer materials
  • 900W high-torque belt-driven servo motor — delivers exceptional power for heavy-duty penetration while remaining quiet and energy-efficient
  • Dual-tension mechanism — supports high-tension stitching with thick threads for maximum seam strength on the heaviest materials
  • Adjustable presser foot lift (8–20 mm) — accommodates thick stacks of fabric or leather with ease
  • Max 9 mm stitch length — versatile stitch range for both functional and decorative heavy-duty applications
  • Safety clutch — protects the hook from damage during difficult material transitions; reset with a simple button press

Ideal For

  • Large upholstery projects — sofas, sectionals, oversized cushions, and furniture panels
  • Automotive and marine interiors — car seats, dashboards, boat seats, and interior trim
  • Canvas and heavy textiles — tents, tarps, truck covers, and industrial enclosures
  • Leather goods — saddlery, heavy bags, protective gear, and multi-layer leather work
