Overview of SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains
SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains are highly durable and corrosion-resistant chains that are specifically designed for heavy-duty applications. These chains feature specially treated pins, bushes, and rollers that provide enhanced wear resistance and extended chain life. They are ideal for use in harsh environments, such as food processing, automotive, and marine applications. These chains are essential components of mechanical power transmission systems, providing reliable and efficient transfer of power from one component to another. The image below shows the SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains in action.

Structure and Composition of SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains
SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains are composed of high-quality stainless steel, which makes them resistant to corrosion and wear. Their structure consists of several key components:
- Link plates: The link plates are where the chains connect to sprockets. They are made of two identical plates held together by pins and bushings, forming a link.
- Pins: The pins are cylindrical components that hold the link plates together. They are made of hardened steel to withstand high stresses and loads.
- Bushings: The bushings are cylindrical components that fit into the link plates and surround the pins. They reduce friction between the pins and link plates, prolonging the life of the chain.
- Rollers: The rollers are cylindrical components that allow the chain to roll smoothly over sprockets. They are made of stainless steel, which makes them durable and corrosion-resistant.
The combination of these components results in a strong and reliable chain that can withstand heavy loads and harsh environments. SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains are widely used in various applications, including food processing, packaging, and marine industries.

Working Principle of SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains
The SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains are an essential component in mechanical power transmission systems. These chains work on the basic principle of transferring power from one rotating shaft to another using the rollers that are mounted on the pins of the chain.
These chains have a number of performance characteristics that make them ideal for use in heavy-duty applications. The rollers in these chains reduce the friction between the chain and the sprocket teeth, resulting in the efficient transfer of power. Additionally, the high strength and durability of stainless steel make these chains capable of withstanding heavy loads and harsh environmental conditions.
In summary, the SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains are designed to provide reliable and efficient power transmission in demanding applications. Their unique design and material properties make them an ideal choice for use in heavy-duty machinery.

Maintenance and Care for SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains
To ensure the longevity and optimal performance of the SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains, proper maintenance and care must be taken. Below are some essential maintenance and care tips:
1. Regular Lubrication: Lubricate the chain regularly with high-quality lubricants to prevent rust and corrosion. This will also help reduce friction, heat, and wear on the chain.
2. Proper Tension: Ensure that the chain tension is correct to prevent excessive wear and elongation of the chain.
3. Inspection: Inspect the chain regularly for any signs of wear, damage, or misalignment. Replace any damaged or worn-out parts immediately.
4. Cleaning: Clean the chain regularly to remove any dirt, debris, or contaminants that may cause damage or reduce the chain's efficiency.
5. Storage: When not in use, store the chain in a clean, dry, and covered area to prevent rust or corrosion.
By following these maintenance and care tips, you can ensure the SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains' optimal performance, longevity, and safety.

Why Choose Our Stainless Steel Roller Chains?
Our SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains offer outstanding advantages in terms of strength and durability. Unlike regular stainless steel chains that have a similar strength to carbon steel, our chains can reach 60%-70% of carbon steel strength. We offer chains in various series including 300, 400, and 600.
One of our biggest strengths lies in the high-quality chain plates. During the heat treatment process, the chain plates undergo controlled deformation or stress relief through pressure, ensuring precise dimensions and mechanical performance. The chain plates are also subjected to high-pressure processing to enhance material durability.
The chain plates have uniform thickness and two bright strips formed by double punching, resulting in close contact with small tubes and shafts, ensuring high precision and tight fit. All holes are centrally positioned on the chain plates without any deviation. The chain plates have high flatness.

How To Select Sprockets For Stainless Steel Chains?
When it comes to selecting sprockets for heavy-duty stainless steel roller chains such as the SS28AH-3/SS140H-3 series, there are a few things to consider. Firstly, you need to ensure that the sprocket is compatible with the chain's pitch, which is the distance between the centers of two adjacent rollers. You also need to consider the number of teeth on the sprocket and how it will affect the speed and torque of the chain.
At our company, we offer a wide range of sprockets designed to fit various sizes and pitches of stainless steel chains. Our sprockets are made from high-quality materials to ensure maximum durability and longevity, even in harsh environments. We also provide custom sprockets to meet the unique needs of our customers.
