The SS24AH-2/SS120H-2 chains play a crucial role in ensuring smooth and efficient power transfer within mechanical drive systems, making them an essential component for industrial operations.
The SS24AH-2/SS120H-2 Heavy Duty Series Stainless Steel Roller Chains are engineered with a robust structure and a carefully composed composition. Below are the key points that describe the structure and composition of this remarkable product:
Here is an image depicting the structure of the SS24AH-2/SS120H-2 Heavy Duty Series Stainless Steel Roller Chains:


The SS24AH-2/SS120H-2 Heavy Duty Series Stainless Steel Roller Chains are designed to transmit power and bear heavy loads in mechanical applications. Their working principle involves the use of cylindrical rollers that are held between inner and outer link plates of the chain. This creates a flexible and durable connection between sprockets that allows for smooth and efficient power transmission.
The performance characteristics of these chains include high strength, wear resistance, and corrosion resistance due to their stainless steel construction. The cylindrical rollers reduce friction between the chain and sprocket teeth, resulting in less wear and longer service life. Additionally, their ability to handle heavy loads makes them suitable for use in demanding applications such as mining, construction, and agriculture.
Proper maintenance and care are essential to ensure the longevity and optimal performance of the heavy-duty stainless steel roller chains, such as the SS24AH-2/SS120H-2 series. Follow these steps for cleaning, lubricating, and conducting regular inspections:
By following these maintenance and care recommendations, you can extend the lifespan of your SS24AH-2/SS120H-2 Heavy Duty Series Stainless Steel Roller Chains and ensure their reliable performance in demanding applications.

Our SS24AH-2/SS120H-2 Heavy Duty Series Stainless Steel Roller Chains offer exceptional strength and durability. While the general strength of stainless steel is equivalent to that of carbon steel, our stainless steel chains can achieve 60%-70% of carbon steel's strength. Our chains are available in 304, 316L (resistant to strong acid and corrosion), and 310S (resistant to ultra-high temperatures).
Our chains have small clearances and high tightness. Our biggest advantage comes from our high-quality chain plates. During the heat treatment process, pressure is controlled to deform or eliminate internal stress, ensuring the chain's dimensional accuracy and mechanical properties. The chain surface undergoes high-pressure processing to increase material durability. The thickness of the chain plate is uniform, and the bright band formed by punching twice ensures a tight fit between the small pipe and the pin. All holes are located in the center of the chain plate, with no deviation. The flatness of the chain plate is high.

Choose Raydafon Stainless Steel Roller Chains for unmatched strength, durability, and precise dimensions.
