Genuine Bobbin Case Cap (91-140-287-91) for Pfaff 1245 & 1246
Maintain precise lower-thread tension with the 91-140-287-91 Genuine Bobbin Case Cap (also identified by the manufacturing code CP-HPF1242). This high-precision component is specifically engineered for the Pfaff 1245 and 1246 industrial series, serving as the critical housing and tension regulator for your bobbin.

A genuine cap is essential for achieving the balanced, professional "lockstitch" that Pfaff walking foot machines are famous for, particularly when using heavy-duty upholstery threads.

Key Features & Benefits
Exact OEM Tension Control: Features a factory-calibrated tension spring and leaf that provides consistent resistance, preventing thread backlash and "birdnesting" at the start of seams.

Precision Latch Mechanism: The integrated latch is designed for a secure "click-lock" fit into the hook base, ensuring the bobbin remains stable even during high-speed, high-vibration operation.

Micro-Polished Thread Path: Every surface that the thread contacts is polished to a mirror finish to eliminate friction, which is vital for preventing the shredding of bonded nylon or polyester threads.

Hardened Steel Build: Forged from high-grade industrial steel to resist the "grooving" that can be caused over time by the constant passage of abrasive synthetic threads.
