Import Bso-737f-504m2-04 — Buy in Bulk from Supplier in China

The BSO-737F-504M2-04 is an industrial sewing machine component designed for heavy-duty applications, including garment manufacturing and upholstery. It features a robust construction with high-strength steel alloys to withstand repetitive stress and extend operational life. The model is compatible with single-needle lockstitch machines, offering precision stitching for thick fabrics like denim, canvas and leather.

Key materials include hardened steel for the needle bar, chrome-plated surfaces for corrosion resistance and nylon or polyurethane for moving parts to reduce friction. Typical industry standards for such components include Rockwell hardness of 50-60 HRC for critical parts, surface finishes of Ra 0.8-1.6 µm and dimensional tolerances of ±0.02 mm for mating surfaces. The component’s design minimizes vibration and noise during high-speed operation (standard: 4000-5000 RPM).

This component is used in textile factories, automotive seat manufacturers and furniture producers requiring reliable, high-volume stitching. It supports applications involving multiple fabric layers, with typical thread sizes ranging from Tex 30 to Tex 120. Buyers should confirm compatibility with their machine models, as variations in mounting dimensions or thread paths may exist.
