BROTHER S-7250A-705 STANDARD VERSION (HEAVY WEIGHT) LOCKSTITCH INDUSTRIAL SEWING MACHINE

The Brother S-7250A-705 is a robust single needle industrial lockstitch machine designed specifically for heavy-weight materials. Featuring Brother’s groundbreaking DigiFlex Feed (DFF) system—the world’s first electronic feed control, this machine brings digital precision to fabric feeding, significantly reducing needle breakage, puckering, and material slippage, even when handling thick or layered fabrics.

This model is equipped with a minimum lubrication system and a sealed oil pan, effectively eliminating oil stains and keeping fabrics clean throughout production. The S-7250A-705 also features stepping motor control for smoother, quieter reverse stitching, improved responsiveness, and consistent thread tension across various materials.

Fully compatible with IoT systems, the machine enables remote monitoring, process optimisation, and productivity tracking, making it ideal for smart factory setups. With a max stitch length of 7mm, precision controls, and USB compatibility for data transfer and software upgrades, this machine is built for heavy-duty commercial environments.
