Work Smarter

The Jack JK-58720J-E was designed to improve operator efficiency and reduce fatigue. Built on the same all steel chassis as the rest of the Jack lineup and driven by the coaxial direct drive AC servo motor, the JK-58720J-E is full of features not found on competitively priced machines.

Simplified Control

The JK-58720J-E control panel is simple and intuitive. From the control panel the user can adjust sewing speed, set needle position (up/down), turn on/off auto thread trimmer function, set automatic foot lifter operation, turn on/off electronic thread tension, set bartacking function or even program segmented sewing allowing the operator to repeat simple sewing tasks like sewing labels or pockets.

User Friendly

The Jack JK-58720J-E comes standard with integrated adjustable LED lighting, a half/full stitch button and a reverse button that can be used instead of the reverse lever. The presser foot can be raised by hand or automatically by foot pedal. On top of the machine is an integrated bobbin winder, allowing you to wind bobbins while continuously sewing.

Direct Drive

No complicated motors or belts to deal with; the Jack JK-58720J-E comes equipped with an integrated AC servo motor. The servo motor is mated to the machine head by a proprietary coaxial shaft that reduces vibration and noise; this allows the user to perform consistent seams at any speed.

Automatic Foot Lifter

The Jack JK-58720J-E features an automatic foot lifter with a variety of settings. The foot lifter can be set to automatically lift by slightly depressing the foot pedal backwards. There are several settings that can be adjusted by the push of a button depending on the needs of the sewing operation.

Improved Thread Trimmer

The Jack JK-58720J-E features an improved automatic thread trimmer that allows for the cutting of heavier weight thread without issue. The thread trimmer function can be tuned on or off depending on the sewing operation with just a simple push of a button. Once turned on, fully depress the foot pedal backwards to cut the thread.

Dry Head

The Jack JK-58720J-E head was designed to operate dry by utilizing a special DLC (Diamond Like Carbon) coating on the needlebar. This coating allows the machine head to operate without the use of lubricating oil virtually eliminating the possibility of oil contamination on fabrics.

Oil Shield Technology

The Jack JK-58720J-E "Oil Shield" technology features a redesigned oil lubrication system further reducing the possibility of oil contamination on fabrics. The oil pan has been integrated into the machine and sealed. This system combined with the dry head creates a "Semi Dry" lubricating system that eliminates oil contamination on fabrics.

Large Hook

The Jack JK-58720J-E comes standard with an enlarged hook system allowing for longer sewing sessions without interruption.

Modern Design

The Jack Sewing Machine Co. LTD, lineup of machines have all undergone design updates improving not only functionality but aesthetics. In addition to the redesigned machine head, the heavy duty table and stand have all undergone updates as well. Each machine ships as a complete set.
