Steel Bobbin with Slot (Part #2996) – For Singer 31 & 331K
Ensure peak performance in your industrial sewing setup with the Steel Bobbin (Part #2996). Specifically designed for the oscillating shuttle systems of Singer 31 and 331K machines, these bobbins are engineered for high-speed durability and precise thread delivery. Featuring the classic "slotted" design, they allow for easy thread anchoring and consistent winding.
Key Performance Features
Precision-Machined Steel: Unlike plastic or lightweight aluminum alternatives, these steel bobbins provide the necessary weight and balance for stable rotation within the shuttle race at high industrial speeds.
Integrated Thread Slot: The vertical slot on the hub allows for quick and secure anchoring of the thread when starting the winding process, preventing slippage.
Smooth-Finish Flanges: Each bobbin is polished to remove burrs and sharp edges, ensuring the thread pays out smoothly and prevents snagging or breakage inside the bobbin case.
Perfect Dimensional Accuracy: Manufactured to the exact OEM specifications for the Singer 2996, ensuring a perfect fit in the bobbin case and preventing "wobble" that can cause uneven tension.
