Genuine Rotary Hook and Bobbin Case Base (91-140-539-91) for Pfaff 1245 & 1246
Restore the mechanical heart of your machine with the 91-140-539-91 Genuine Hook and Base. This is the primary vertical-axis hook assembly specifically engineered for the Pfaff 1245 and 1246 series.

As a critical component for stitch formation, this genuine assembly ensures perfect timing and thread loop pickup, even when using the thickest bonded threads required for automotive upholstery, marine canvas, and heavy leatherwork.

Key Features & Benefits
Precision Timing: Manufactured to the exact tolerances of the Pfaff factory, ensuring the hook point passes the needle at the precise millisecond required for consistent loop catch.

High-Speed Stability: Balanced for industrial speeds, reducing vibration and heat buildup during long production runs.

Superior Thread Clearance: The hook and base geometry are optimized to allow heavy threads (up to size T-210/V-207) to pass smoothly around the bobbin case without snagging or shredding.

Hardened Steel Construction: Built from ultra-durable, heat-treated steel to resist the abrasive wear of high-tenacity synthetic threads and the impact of occasional needle strikes.
