Speedway SW-4400-L18 Single Needle 18" Long Arm Triple Feed Walking Foot Lockstitch Sewing Machine Complete Unit with Table and Servo Motor

This industrial single-needle long-arm machine is engineered for oversized, multi-layer projects that demand exceptional workspace and penetration power. The 18-inch arm and 6.5-inch height clearance provide the extended workspace needed for large upholstery panels, boat covers, automotive interiors, and bulky assemblies that won't fit under standard machines. Its unison feed walking foot system synchronizes top and bottom feeding to prevent material slippage when working with leather, vinyl, canvas, and heavy multi-layer materials. The dual-tension mechanism supports high-tension stitching with thick threads, making it ideal for applications requiring maximum seam strength such as saddlery, industrial straps, safety harnesses, and heavy-duty textile work.

MACHINE APPLICATIONS:

  • 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
  • Industrial straps and webbing — cargo belts, safety harnesses, and load-bearing assemblies

MACHINE 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

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.
