BROTHER S-7250A-905 STANDARD VERSION (HEAVY WEIGHT) LOCKSTITCH INDUSTRIAL SEWING MACHINE (AUTO FOOT LIFT)

The Brother S-7250A-905 is a heavy-duty lockstitch industrial sewing machine designed to tackle demanding sewing tasks with precision, speed, and durability. Built with automatic presser foot lift (Auto Foot Lift) and DigiFlex Feed (DFF) technology, this machine delivers superior fabric handling, especially on thick or multi-layered materials.

Equipped with stepping motor-driven feed control, it significantly reduces issues like needle breakage, puckering, and material slippage, even on bulky seams. A sealed oil pan and minimum lubrication system ensure a clean work environment and reduce the risk of oil stains on your fabrics.

Designed for professional use in manufacturing settings, the S-7250A-905 includes advanced features like reverse sewing vibration suppression, programmable stitch length, and USB data management. It is also IoT-ready, allowing smart factory integration for real-time production monitoring and maintenance tracking.
