Bobbin Cases Tajima No Backlash L

Tajima Style "L" No-Backlash Bobbin Case | Commercial Embroidery (Base SKU: 707 | System: L-Style | Sold Individually)

The Professional Solution for Consistent High-Speed Tension. Are you battling inconsistent bobbin tension or "bird-nesting" during high-speed commercial runs? The Tajima Style "L" No-Backlash Bobbin Case is the industrial standard for precision embroidery. Featuring a specialized anti-backlash spring, this case prevents the bobbin from "spinning on" after the machine stops, eliminating the slack that causes thread breaks, looping, and costly downtime.

Is this case for you? ⚠️ COMPATIBILITY CHECK: This is an "L" STYLE (Standard) bobbin case. It is designed strictly for Commercial/Industrial Embroidery Machines (e.g., Tajima, Barudan, SWF, Ricoma, Brother PR Series). This is the most common bobbin size for professional embroidery, but it will NOT fit "M" style (Jumbo) hooks or home sewing machines.

Key Performance Features

Anti-Backlash Spring: The built-in leaf spring applies constant, gentle pressure to the bobbin. This prevents the bobbin from over-spinning when the machine jumps or trims, ensuring your tension is perfect from the very first stitch of the next segment.

Precision Tension Control: Engineered with a high-quality, polished tension spring for smooth thread delivery. This is essential for maintaining crisp "satin stitches" and preventing top-thread looping on high-speed industrial runs (1,000+ SPM).

OEM-Grade Durability: Produced to the exact tolerances required by leading machine manufacturers to ensure a vibration-free fit in the hook race. This precision protects your machine's timing and reduces wear on the rotary hook.

Best Use Practices

Primary Use: High-speed commercial embroidery on all garment types, including caps, polos, and outerwear.

Tension Maintenance: We recommend checking your bobbin tension daily with a tension gauge. For most commercial applications, your "L" style bobbin should pull at approximately 18 to 22 grams of resistance.

Cleaning Protocol: Keep a clean hook! Use canned air or a small brush to remove lint from the tension spring daily. Even a tiny piece of lint under the spring will cause your bobbin tension to fail, leading to "white-showing" on the top of your design.
