The SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains exhibit a robust and intricate structure, designed to withstand demanding industrial applications. Composed of high-quality stainless steel materials, these chains are built for durability and longevity.
Key features of the structure and composition of SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains:

Our SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains are made of advanced materials that exhibit excellent performance in acidic and alkaline environments that come into direct contact with food. The chains are exposed to water and are required to withstand high or low temperatures (-40 to +400 degrees Celsius) that demand corrosion resistance.
These chains are composed of austenitic stainless steel components that are highly resistant to rust. Additionally, all components undergo surface machining to eliminate stress factors. The chains have a tensile strength of approximately 65% of that of standard carbon steel chains.

SS28AH-3/SS140H-3 heavy duty series stainless steel roller chains operate based on the principle of transmitting power between rotating machinery parts. The chain is specifically designed to handle heavy loads in demanding environments.
As the chain moves around the sprockets, the rollers engage with the teeth of the sprocket, transmitting power and torque from the driving sprocket to the driven sprocket. The chain's links, pins, and bushings all work together to maintain the proper pitch and ensure smooth power transfer.
The performance characteristics of the SS28AH-3/SS140H-3 heavy duty series stainless steel roller chains make them ideal for use in high load and demanding applications. The chains are designed to handle shock loading, high-speed operation, and heavy loads while maintaining their strength and durability.
Proper maintenance and care are crucial for ensuring the longevity and optimal performance of heavy-duty stainless steel roller chains. Follow these steps to correctly maintain and care for your heavy-duty stainless steel roller chains:
By following these maintenance and care guidelines, you can extend the lifespan of your SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains and ensure their smooth operation.

Our SS28AH-3/SS140H-3 Heavy Duty Series Stainless Steel Roller Chains offer a number of outstanding advantages. Our chains are highly durable, with a strength that is 60%-70% that of carbon steel, far exceeding that of typical stainless steel chains. We offer chains made from 304 and 316L stainless steel, which are highly resistant to strong acids and corrosion, as well as 310S stainless steel, which is capable of withstanding extremely high temperatures.
Our chains have small gaps and high tightness, ensuring a precise fit. Our greatest advantage, however, is the exceptional quality of our chain plates. During the heat treatment process, our plates undergo controlled deformation or stress relief through pressure control during the cooling process, ensuring the dimensional accuracy and mechanical performance of our chains. Additionally, our chain plates undergo high-pressure processing to increase their durability. Our plates are uniformly thick, with shiny bands formed by two rounds of punching, ensuring a tight fit between tubes and shafts. All holes are precisely located in the center of the plate, with no deviations. Our plates have high flatness, ensuring optimal performance.

When selecting sprockets for your SS28AH-3/SS140H-3 heavy duty series stainless steel roller chains, there are a few important factors to consider. First, you'll need to determine the correct pitch diameter and bore size for your application. This will ensure that the sprocket properly fits your chain and is able to transfer power efficiently.
Next, consider the number of teeth on your sprocket. A higher number of teeth will result in a slower chain speed, while a lower number of teeth will increase the speed. You'll also need to determine the desired ratio between the sprocket and the driver. This will affect the torque and speed of your machinery.
At our company, we offer a wide selection of sprockets to fit your needs. From standard to custom designs, we can provide the right sprocket for any application. Our sprockets are made from high-quality materials to ensure long-lasting durability, even in harsh environments.
