Introduction
The SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains are an exceptional choice for demanding applications. With their advanced features and rugged construction, these roller chains are ideal for use in a wide range of industrial applications. These chains are constructed using high-quality materials and are designed to withstand high loads and extreme conditions. They are widely used in mechanical power transmission systems, providing reliable operation and long service life. The SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains are an essential component in any heavy-duty mechanical power transmission system.
Structure and Composition of SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains
- The SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains consist of interconnecting links, rollers, and pins.
- The links are made of high-quality stainless steel and have two side plates, which hold the chain together.
- The rollers are also made of stainless steel and rotate around the pins to provide smooth and efficient movement.
- The pins are made of hardened stainless steel and hold the rollers in place, while also allowing them to rotate freely.
- The chain is lubricated to ensure smooth operation, reduce wear, and increase lifespan.

Material
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:
- All parts are made from austenitic stainless steel, which offers excellent rust resistance.
- All components undergo surface finishing to eliminate stress risks.
- The tensile strength is approximately 65% higher compared to standard carbon steel chains.

Working Principle of SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains
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.
Maintenance and Care of SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains
Proper maintenance and care of heavy duty stainless steel roller chains are vital to ensure their longevity and efficient performance. Here are some recommended steps for maintaining and caring for SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains:
- Cleaning: Clean the chains regularly to remove any dirt, debris, or buildup. Use a soft-bristled brush, mild detergent, and warm water to clean the chains. Avoid using harsh chemicals or high-pressure water, as they can damage the chains.
- Lubrication: Lubricate the chains regularly to reduce friction between the moving parts and prevent wear and tear. Use a high-quality lubricant specifically designed for stainless steel chains. Apply the lubricant evenly to the chains while they are in motion.
- Regular Inspection: Inspect the chains regularly to identify any signs of wear or damage. Look for bent, broken, or cracked links, and replace them immediately. Check the tension of the chains and adjust them if necessary.

Why Choose Ever-power Stainless Steel Roller Chains?
Ever-power 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.

How To Select Sprockets For Stainless Steel Chains?
When selecting sprockets for SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains, it is important to consider the chain speed, pitch, number of teeth, bore size, and material. The correct sprocket will ensure optimal chain performance and longevity.
Firstly, the sprocket pitch must match the chain pitch. The pitch is the distance between each chain pin, and it is essential to choose a sprocket with the same pitch to ensure proper engagement and smooth operation.
Secondly, consider the chain speed. Select a sprocket with a maximum speed rating that matches or exceeds the chain speed to prevent premature wear and failure.
Thirdly, the number of teeth on the sprocket must be selected to match the desired speed ratio. A larger sprocket will result in a slower speed, while a smaller sprocket will result in a faster speed.
Fourthly, ensure that the bore size of the sprocket matches the shaft diameter to ensure proper fit and alignment.
Lastly, choose a sprocket material that is compatible with the chain material. For stainless steel chains, it is best to select a stainless steel sprocket to prevent corrosion and ensure longevity.
At our company, we offer a wide variety of sprockets for stainless steel chains, including SS24AH-1/SS120H-1 Heavy Duty Series Stainless Steel Roller Chains. We provide various sizes and materials to ensure that you find the perfect fit for your application.
