Working Principle of SS28AH-2/SS140H-2 Heavy Duty Series Stainless Steel Roller Chains
SS28AH-2/SS140H-2 Heavy Duty Series Stainless Steel Roller Chains are used in mechanical power transmission systems and are designed to transmit power and withstand heavy loads. The working principle of these chains is based on the meshing of the rollers with the sprocket teeth. As the chain rotates, the rollers move along the sprocket teeth, transmitting power from the driver sprocket to the driven sprocket.
The heavy-duty construction and stainless steel material of these chains provide excellent performance characteristics in terms of strength, durability, and corrosion resistance. The chains are capable of withstanding high shock loads and providing smooth operation even in harsh environments.

Maintenance and Care for SS28AH-2/SS140H-2 Heavy Duty Series Stainless Steel Roller Chains
Proper maintenance and care are essential for ensuring the longevity and optimal performance of SS28AH-2/SS140H-2 Heavy Duty Series Stainless Steel Roller Chains. Here are some important points to consider:
- Regular Cleaning: Clean the chains using a mild detergent and water solution to remove dirt, debris, and contaminants. Avoid using harsh chemicals that can damage the stainless steel surface.
- Lubrication: Apply a high-quality lubricant specifically designed for stainless steel chains. This helps reduce friction, prevent wear, and extend the chain's lifespan. Follow the manufacturer's recommendations for lubrication intervals.
- Inspection: Regularly inspect the chains for signs of wear, corrosion, or damage. Check for elongation, misalignment, or loose attachments. Replace any worn or damaged components promptly.
- Tension Adjustment: Maintain proper tension in the chains to prevent excessive stress and extend their life. Follow the manufacturer's guidelines for tension adjustment and use appropriate tensioning tools.
- Storage: When not in use, store the chains in a dry and clean environment to prevent rust and corrosion. Protect them from extreme temperatures, moisture, and direct sunlight.
By following these maintenance and care practices, you can ensure that your SS28AH-2/SS140H-2 Heavy Duty Series Stainless Steel Roller Chains perform reliably and have an extended service life.

Why Choose Our Stainless Steel Roller Chains?
Our SS28AH-2/SS140H-2 Heavy Duty Series Stainless Steel Roller Chains offer exceptional advantages compared to standard stainless steel chains. They possess a high strength that is typically 60%-70% of carbon steel, surpassing the general strength of stainless steel. These chains are available in 300, 400, and 600 series materials.
One of our greatest strengths lies in the superior quality of the chain plates. During the heat treatment process, the chain plates undergo controlled deformation or stress elimination through pressure during the cooling phase. This ensures precise dimensions and mechanical performance of the chains. Furthermore, the chain surface goes through high-pressure processing to enhance material durability.
The uniform thickness of the chain plates and the bright band formed by double punching enable tight contact with small pipes and pins, achieving high precision fitting. All holes are positioned centrally in the chain plates without any deviation. The chain plates also exhibit high flatness.

How To Select Sprockets For Stainless Steel Chains?
When choosing sprockets for your SS28AH-2/SS140H-2 Heavy Duty Series Stainless Steel Roller Chains, there are a few factors to consider. First, you'll need to know the pitch of your chain, which refers to the distance between the centres of adjacent pins. This will determine the pitch diameter of the sprocket you need to choose.
Next, you'll need to consider the number of teeth on the sprocket. This will affect the speed ratio between the driver and driven sprocket. You can use the formula RPM driven = RPM driver x (driver teeth / driven teeth) to calculate this ratio.
It's also important to consider the type of tooth profile you need. Standard or "stock" tooth profiles are the most common and work well for most applications. However, if you require a specific tooth profile, such as a custom profile for high-speed applications, we offer those as well.
At our company, we offer a variety of stainless steel sprockets for sale, including single, double, and triple strand sprockets. We also offer both stock bore and custom bore sprockets to meet your specific needs. Our sprockets are made from high-quality stainless steel, ensuring they are durable and corrosion-resistant.
