Round pin type silent chains are a type of chain that combines low noise, high reliability, and efficient transmission performance, widely used in industrial transmission, automobile manufacturing, precision machinery and other fields. Their design centers on the two core principles of "silence" and "durability", achieving stable operation through unique structures and processes.
Low-noise operation:
The special rocker joint design and roller pin meshing structure significantly reduce friction, impact, and vibration during the chain's operation. Compared with traditional chains, the noise is significantly reduced, making them suitable for scenarios with high requirements for quietness in the working environment (such as precision instruments and indoor equipment).High strength and wear resistance:
High strength and wear resistance:
Key components such as pins and link plates are made of high-strength alloy materials and strengthened through heat treatment. They possess high hardness and anti-fatigue properties, capable of withstanding large loads (especially suitable for high-torque transmission). Meanwhile, they have excellent wear resistance, prolonging their service life.
