Premium Replacement Bobbin Case Spring Ø18MM 367150270 for Dürkopp Adler 291 & 292 Sewing Machines
The 367150270 bobbin case spring (Ø18mm) is a premium replacement-grade tension spring designed for Dürkopp Adler 291 and 292 industrial sewing machines. It is installed inside the bobbin case assembly and plays a vital role in maintaining consistent lower thread tension and smooth thread release during high-speed sewing.
Manufactured to meet or closely match original specifications, this spring ensures stable stitch formation, reduced thread breakage, and improved seam consistency, especially when working with heavy-duty materials such as leather, upholstery, and technical fabrics.
This Ø18mm spring is widely used in the hook and bobbin system of the 291/292 series, helping maintain proper balance between upper and lower thread tension for reliable industrial performance.
