Genuine Vintage Singer Needle Bar Assembly - Complete 3-Part Set

SIMANCO (Singer Manufacturing Company) stamped parts represent authentic Singer quality and precision engineering. In excellent pre-owned condition, this complete assembly maintains the original specifications for reliable performance.
Complete Assembly Includes Three Parts
This listing provides the complete needle bar assembly with all connecting components:
- Needle Bar (Part # 125377) - Also referred to as needle shaft. Polished steel construction. Holds the needle and moves up and down to create stitches.
- Needle Bar Connector (Part # 125276) - Includes mounting screw. Connects the needle bar to the connecting arm.
- Needle Bar Connecting Arm (Part # 125275) - Includes mounting screw. Cast construction. Links the connector to the main driving shaft to transfer motion.
How the Needle Bar Assembly Works
The needle bar assembly is the critical mechanism that creates the up-and-down needle motion essential for stitch formation:
- Needle Bar: Holds the needle securely and moves it up and down through the fabric
- Connector (125276): Connects the needle bar to the connecting arm, transferring motion from the drive system
- Connecting Arm (125275): Links to the main driving shaft, converting rotary motion into the precise vertical needle movement
- Synchronized Motion: All three parts work together to ensure accurate needle timing and consistent stitch formation
When to Replace Your Needle Bar Assembly
Common issues requiring needle bar assembly replacement include:
- Bent Needle Bar: The needle bar can become bent from needle strikes or improper handling, causing timing issues and poor stitch quality
- Broken Connecting Arm: The cast connecting arm can crack or break from years of use or stress
- Worn Connections: Pivot points and connection points wear over time, causing play and timing problems
- Missing Parts: Lost during machine disassembly or restoration
- Restoration Projects: Replacing worn or damaged components to restore vintage machines to working condition
