Working Principle of SS12AH-1/SS60H-1 Heavy Duty Series Stainless Steel Roller Chains
The heavy duty series stainless steel roller chains, SS12AH-1 and SS60H-1, work on the principle of transmitting power and bearing loads in mechanical drives. As the chain rotates around the sprockets, the rollers on the chain engage with the teeth of the sprocket, creating a positive engagement and transferring the power from the driving sprocket to the driven sprocket or load.
The performance characteristics of the SS12AH-1/SS60H-1 heavy duty series stainless steel roller chains include high strength, wear resistance, corrosion resistance, and the ability to withstand harsh environments. These properties make them ideal for use in applications where heavy loads, high speeds, and harsh operating conditions are present.

Maintenance and Care for SS12AH-1/SS60H-1 Heavy Duty Series Stainless Steel Roller Chains
Proper maintenance and care are crucial for ensuring the longevity and performance of SS12AH-1/SS60H-1 Heavy Duty Series Stainless Steel Roller Chains. Here are some tips to keep these chains in good condition:
- Regularly inspect the chain for any signs of wear, such as elongation, corrosion, or broken links.
- Clean the chain regularly with a mild solvent or detergent to remove dirt and debris that can cause wear and tear.
- Ensure proper lubrication by applying a high-quality lubricant to the chain during operation. This can reduce friction and prevent premature wear.
- Check the tension of the chain regularly to ensure proper alignment and prevent excess slack, which can cause damage to the chain and sprockets.
- Store the chain in a clean and dry environment when not in use to prevent corrosion and other damage.
By following these maintenance and care guidelines, you can ensure that your SS12AH-1/SS60H-1 Heavy Duty Series Stainless Steel Roller Chains continue to perform optimally for years to come.

Why Choose Our Stainless Steel Roller Chains?
Our SS12AH-1/SS60H-1 Heavy Duty Series Stainless Steel Roller Chains offer outstanding advantages that set us apart from others in the industry:
- High Strength: While regular stainless steel has the strength of carbon steel, our stainless steel chains can reach 60%-70% of carbon steel strength.
- Material Options: We offer chains in 300, 400, and 600 series, providing a wide range of options to suit your specific needs.
- Tight Tolerances: Our chains have small clearances and high precision, ensuring a tight fit.
- Superior Chain Plate Quality: Our chain plates undergo a heat treatment process that involves controlled deformation or stress relief during the cooling process, guaranteeing dimensional accuracy and mechanical performance.
- Surface Treatment: We apply high-pressure processing to the chain surface, increasing the durability of the material.
- Uniform Plate Thickness: The bright bands formed by double punching ensure close contact between small tubes and pins, resulting in high precision fit.
- Centralized Hole Positioning: All holes are located at the center of the chain plates, eliminating any deviation.
- High Flatness: Our chain plates have a high level of flatness.

How To Select Sprockets For Stainless Steel Chains?
When selecting sprockets for SS12AH-1/SS60H-1 Heavy Duty Series Stainless Steel Roller Chains, it is important to consider the chain pitch, number of teeth, bore size, and overall design.
The chain pitch refers to the distance between the centers of two adjacent pins. The sprocket pitch must match the chain pitch for proper engagement and operation.
The number of teeth on the sprocket determines the speed ratio and torque transmission capabilities. A larger sprocket will result in higher speed but lower torque, while a smaller sprocket will provide higher torque but slower speed.
The bore size of the sprocket must also match the shaft of the machine it is being attached to for proper alignment and secure installation.
At our company, we offer a wide range of sprockets for stainless steel chains in various sizes and configurations to fit your specific needs. Whether you require a stock sprocket or a custom-made design, we have the expertise and resources to provide you with a reliable and efficient solution.
Please see the attached image for an example of our stainless steel sprockets.
