The JACK JK-58750B is an industrial double needle needle-feed lockstitch machine featuring a split needle bar mechanism for independent needle control — enabling precise corner stitching and complex seam patterns. Powered by a 750W direct-drive servo motor with large-capacity hooks, semi-dry lubrication, and a 3-level LED work light, it handles medium to heavy-duty fabrics at up to 3,000 SPM and arrives fully assembled with table and stand.

Key Features
Split needle bar mechanism — each needle can be controlled independently, enabling precise corner stitching, pattern work, and complex seam construction
Large-capacity hook and bobbin — reduces bobbin change frequency, keeping production moving longer between interruptions
750W direct-drive servo motor — energy-efficient, low-vibration operation with smooth needle penetration across material weights
Semi-dry lubrication system — provides optimal lubrication while preventing oil stains on finished fabrics
Needle position sensor — precise needle positioning improves stitch accuracy and consistency at high speeds
3-level adjustable LED work light — clear needle area visibility reduces eye strain during extended production runs
Integrated bobbin winder — conveniently located for quick, easy bobbin winding without leaving the machine
Ideal For
Denim, canvas, and medium to heavy woven fabric production
Jeans, workwear, and structured garments requiring precise double-needle seams
Complex seam patterns and corner stitching requiring independent needle control
Production environments prioritizing longer run times with minimal bobbin interruptions
