Heavy-Duty Zigzag Sewing Machine Gears are critical transmission components used in industrial sewing machines designed for extra-thick materials. They transmit power efficiently from the motor to the needle bar, feed mechanism, hook assembly, and zigzag motion mechanism, ensuring smooth, stable, and accurate stitching under heavy loads.
Product Features
Manufactured from premium 20CrMnTi alloy steel, offering excellent strength and toughness.
Carburized and hardened for high surface hardness and outstanding wear resistance.
Precision-machined gear teeth ensure smooth transmission and high meshing accuracy.
Good corrosion and rust resistance for various industrial environments.
High load capacity, ideal for sewing extra-thick materials and heavy-duty applications.
Low noise and vibration contribute to stable machine performance.
