The 12BSS-2 Duplex Short Pitch Stainless Steel Roller Chain is a fundamental element in a range of mechanical transmission systems. It is defined by its durability, strength, and resistance to corrosion. The stainless steel chain plays a vital role in industries including food processing, chemical processing, and medical equipment manufacturing, where it is essential for transmitting power and supporting heavy loads.
The structure of this duplex short pitch stainless steel roller chain comprises three main parts:
The chain plate forms the backbone of the chain, comprised of inner and outer plates connected via a pin.
The roller is the primary load-bearing component of the chain, consisting of the roller body and its axle. The roller body fits into the protrusions on both the inner and outer chain plates, while the roller axle fits onto the chain plate's pin.
The pin is a connecting element that links the chain plate and the roller together.

Our stainless steel chain is crafted from advanced materials, exhibiting high performance in various environments, from acidic and alkaline conditions to direct food contact. The chain is also excellent in areas where corrosion resistance is required, such as exposure to water and extreme temperatures. Furthermore, the chain possesses a tensile strength of approximately 65% that of standard carbon steel chains, offering superb reliability and durability.
Stainless steel roller chains play a crucial role in mechanical transmission, transferring power and bearing loads effectively. The engagement between the chain rollers and the sprocket teeth ensures a smooth, efficient transfer of power, making these chains an indispensable component in numerous industries.
The stainless steel roller chain proves essential across various industries, including food processing, chemical processing, and medical equipment manufacturing. Its corrosion-resistant nature makes it suitable for use in humid, corrosive environments.


Proper maintenance and care are critical for prolonging the service life of stainless steel roller chains. This includes routine cleaning, lubrication, and inspection to ensure optimal performance and prevent premature wear and tear.
Stainless Steel Sprockets serve as the backbone of a robust and durable chain system. Their corrosion-resistant nature ensures longevity, making them ideal for various applications. The precise engagement of the sprocket teeth with the links of the chain guarantees reliable power transmission. This symbiotic relationship enhances the overall performance, reducing wear and tear while maintaining a high level of efficiency.
