GA411N Long Arm Heavy Duty Cylinder Bed Sewing Machine China Factory Suppliers
The GA411N is a professional-grade, long-arm heavy-duty cylinder bed sewing machine engineered specifically for high-density industrial applications. Featuring an impressive arm length of 960mm and a specialized horizontal sewing and feeding design, this machine is the ideal solution for manufacturing boots, long barrel leather products, and other oversized, rigid materials that require precision stitching in a horizontal orientation.
Equipped with a high-capacity JUKI TSC-441 big shuttle hook, the GA411N excels in handling ultra-thick threads—up to metric size 7 (1300D3 or T-400)—without compromising stitch quality. Its expansive working area and robust bottom feeding system ensure seamless operation on the hardest materials, significantly reducing downtime and increasing production efficiency for heavy-duty leather and textile workshops.

Frequently Asked Questions
Q: What makes the GA411N suitable for boot manufacturing?
The GA411N features a 960mm long arm and a horizontal feeding system, which allows it to accommodate the deep, cylindrical shape of boots and long barrel leather products that standard machines cannot reach.
Q: Can this machine handle extremely thick industrial threads?
Yes, thanks to the JUKI TSC-441 big shuttle hook, the GA411N can sew very thick threads, including metric size 7, V415, 1300D3, or T-400.
Q: How does the bobbin capacity affect production efficiency?
The extra-large barrel shuttle hook significantly increases the bobbin thread volume, which reduces the number of times the operator needs to stop the machine to change bobbins.
Q: What is the maximum sewing speed of the GA411N?
The machine has a maximum sewing speed of 800 r.p.m., which is optimized for maintaining stitch precision while working with heavy-duty materials.
Q: Is the lubrication system automatic or manual?
The GA411N utilizes a manual lubrication mode, ensuring that the operator has direct control over the maintenance of the critical moving parts.
Q: Which needle size is recommended for this equipment?
The recommended needle size for the GA411N is DY×3 27#, which provides the necessary strength and penetration for thick leather and industrial fabrics.
