The SS24AH-3/SS120H-3 Heavy Duty Series Stainless Steel Roller Chains are composed of the following:
The pins and bushings are press-fit into the side plates, forming a strong and durable connection. The rollers are free to rotate around the pins, allowing the chain to smoothly engage and disengage from sprockets. The plates are designed to withstand heavy loads and resist wear and corrosion.

The SS24AH-3/SS120H-3 Heavy Duty Series Stainless Steel Roller Chains are made from 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 at extremely high or low temperatures, requiring excellent corrosion resistance (-40 to +400 degrees Celsius).
Key Features:

The SS24AH-3/SS120H-3 heavy-duty series stainless steel roller chains work on the principle of transmitting power from one rotating shaft to another. The chains consist of interlinking plates, pins, and rollers, which engage with the sprockets on the shafts to transfer power.
The performance characteristics of roller chains in power transmission and load bearing are based on their ability to effectively distribute the load along their length. The rollers help reduce friction between the chain and sprocket, allowing for efficient power transmission and reducing wear and tear on the system.
The use of stainless steel in the construction of the chains provides additional benefits, including corrosion resistance and durability. This makes them ideal for use in harsh environments, including those with high moisture or temperature levels.
Proper maintenance and care of heavy duty stainless steel roller chains are essential for ensuring their longevity and optimal performance. Follow these steps for cleaning, lubricating, and inspecting:
By following these steps, you can ensure that your SS24AH-3/SS120H-3 heavy duty stainless steel roller chains remain in optimal condition for longer periods of time.

Our SS24AH-3/SS120H-3 Heavy Duty Series Stainless Steel Roller Chains offer exceptional strength. While typical stainless steel has the strength of carbon steel, our chains can reach 60-70% of the strength of carbon steel. We use high-quality materials, including 304, 316L (resistant to strong acid and corrosion), and 310S (resistant to ultra-high temperatures).
Our chains have small gaps and high precision, ensuring a tight fit. The biggest advantage of our chains is their high-quality chain plates. During heat treatment, the chain plates undergo pressure control to eliminate internal stress and ensure dimensional accuracy and mechanical performance. The chain plates are also processed with high pressure to increase durability. The thickness of the chain plates is uniform, and the punched holes form a bright band, ensuring a tight fit with small tubes and pins. All holes are located in the center of the chain plate, without any skew. The chain plates are highly flat.

Choose Raydafon Stainless Steel Roller Chains for reliable, long-lasting performance in even the toughest applications.
