Jack F5-H — Heavy-Duty Industrial Sewing Machine

The Jack F5-H is the heavy-duty variant of the Jack F5 series, built for reliable, high-performance sewing on medium-to-very heavy materials. It combines a rugged, compact design with industrial features — direct, low-vibration drive, robust construction and user-friendly controls — so you get smooth, precise seams on demanding jobs such as upholstery, heavy garments and technical textiles.

This H-model is configured for heavier needles and fabrics (DP×5 needle system, sizes 18–21) and tuned for stable, powerful stitching at an industrial working speed. Adjustable stitch length, digital speed control and practical on-machine conveniences (thread cutter, adjustable LED light, integrated bobbin winder and needle-stop control) make it easy to work accurately and efficiently.
