Our SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains are made using advanced materials. They perform exceptionally well in acidic and alkaline environments that come into direct contact with food. The chains are exposed to water and operate under high or low temperatures (-40 to +400 degrees Celsius) that require high corrosion resistance.
Key features of our stainless steel chains include:

The SS24AH-1/SS120H-1 heavy duty series stainless steel roller chains are designed to transmit power and bear heavy loads in mechanical drives. These chains are made of high-quality stainless steel, which provides excellent resistance to corrosion, high temperatures, and harsh environments.
The working principle of these chains is based on the interaction between the rollers and the teeth of the sprockets. As the chain rotates around the sprockets, the rollers make contact with the teeth, transmitting power from the driver sprocket to the driven sprocket. The rollers also reduce friction between the chain and the sprockets, allowing for smooth, efficient power transmission.
One of the key performance characteristics of these chains is their ability to withstand heavy loads. The rollers distribute the load evenly across the chain, reducing stress on individual links and increasing the overall strength of the chain. Additionally, the stainless steel construction of these chains provides excellent resistance to wear, ensuring a longer service life.
Overall, the SS24AH-1/SS120H-1 heavy duty series stainless steel roller chains are an excellent choice for applications that require reliable, high-strength power transmission in harsh environments. Their unique design and construction provide superior performance and durability in a wide range of industrial and agricultural applications.

Raydafon Stainless Steel Roller Chains, specifically the SS24AH-1/SS120H-1 Heavy Duty Series, offer exceptional advantages in terms of strength and durability.
Compared to regular stainless steel, our chains have a higher strength, reaching 60%-70% of carbon steel's strength. The materials used include 304, 316L (resistant to strong acid and corrosion), and 310S (resistant to ultra-high temperatures).
One of our greatest advantages lies in the superior quality of our chain plates. During the heat treatment process, we control deformation or eliminate internal stress through pressure, ensuring precise dimensions and mechanical performance of the chains. Additionally, the chain surface undergoes high-pressure processing to enhance material durability.
Our chains have a uniform plate thickness, with bright bands formed by double punching, resulting in tight contact between small tubes and pins. All holes are located in the center of the chain plate, ensuring no deviation. The chain plates have high flatness.
