Genuine Seiko Needle Bar Crank (Part #19414)
Maintain the heavy-duty driving force of your machine with the Genuine Seiko Needle Bar Crank (Part #19414). This precision-engineered internal component is the primary drive link for the needle bar assembly in the Seiko LSW long-arm industrial series.
The needle bar crank is a critical "heartbeat" component that converts the rotational energy of the upper shaft into the powerful, reciprocating vertical motion required for needle penetration. In high-speed industrial environments—especially when sewing through multiple layers of heavy leather, webbing, or thick canvas—the crank is under immense torque. A worn, cracked, or generic crank can cause "knocking" sounds, inconsistent timing, and a loss of penetration power. This genuine Seiko part is balanced and hardened to ensure smooth, vibration-free operation at speeds up to 2,500+ SPM (stitches per minute).
