Efficient Transmission 842/845 Double-Needle Sewing Machine Gear with Steel Teeth Profile ISO 4-6 Grade

What are the characteristics of 842/845 twin-needle machine gear?

842/845 double-needle gear is a commonly used accessories in industrial sewing machines and is mainly used for double-needle sewing equipment. This type of gear is often used to adjust the operating speed and stability of the sewing machine, and is one of the key components in the sewing equipment.

Advantages

High-precision transmission: The gear module and tooth count are precisely designed to ensure smooth sewing machine operation. Typically made from high-quality metal, these components can handle high workloads. Flexible installation: Supports both axial and radial installation to accommodate various equipment needs. High transmission efficiency: Efficient power transfer is achieved through either friction or chain transmission, meeting the specific requirements of double-needle sewing machines when working with thick materials or threads.

842/845 twin-needle machine gear are widely used in the following fields:

In clothing manufacturing, decorative patterns and intricate sewing techniques are used to create garments. For bag production, reinforced and decorative sewing techniques are applied to ensure durability and style. In shoe manufacturing, sewing plays a crucial role in attaching the uppers to the soles. Industrial sewing equipment, particularly the core component of a double-needle sewing machine, is essential for efficient, large-scale production.
