Elevate your machine’s performance with the HAYA BC-DBM(Z1) NBL bobbin case / shuttle core cover — a precision replacement component designed for herringbone / synchronous quilting and DY embroidery machines that use the DBM (Z1) style shuttle system.

Key Features & Benefits

• Precise Fit & Engineering – Manufactured with tight tolerances and premium metal materials, this bobbin case ensures consistent tension control, minimal vibration, and reliable stitch formation.

• Durable & Wear-Resistant – Built from hardened metal alloys to resist wear and deformation even under heavy use, ensuring prolonged service life.

• Smooth Operation – Optimized geometry reduces friction and interference, enabling stable, smooth rotation of the bobbin and shuttle.

• Easy Installation & Replacement – Designed to drop into place in machines built for DBM (Z1) style shuttle / bobbin systems. Offers quick swap-out without heavy modification.

• Enhanced Stitch Quality – Improved stability of the bobbin path helps reduce skipped stitches, thread snarls, and irregular tension in quilting or embroidery operations.

Compatibility & Machine Fit

This bobbin case is intended for synchronous / herringbone quilting and DY embroidery machines that employ the DBM(Z1) / BC-DBM(Z1) NBL style shuttle / bobbin architecture. It is often referenced under “HAYA bobbin case BC-DBM(Z1) NBL” in parts catalogs.

Known machine compatibility (based on vendor listings):

• Some machines from ConSew, e.g. ConSew 146RB, may use this bobbin case as listed in vendor catalogs.

• Some Pfaff KSM-200 models may also be indicated in accessories compatibility lists.

If your machine uses a DBM (Z1) style bobbin / shuttle assembly, this case can be used. However, always verify dimensions (outer diameter, latch position, hook clearance, height) before ordering.

Usage & Maintenance Tips

1. Clean & Debris-Free Installation: Ensure no lint, dust, or thread fragments in the shuttle race or hook area before installing.

2. Lubrication: Use machine-appropriate oil on the pivot / latch interface to reduce friction.

3. Check Tension: After installation, test stitch quality at varying speeds; adjust bobbin tension as required.

4. Routine Inspection: Periodically inspect for wear, burrs or damage; replace if significant wear is evident.
